Answers

Answer 1

For the inequality |x| + 3 > 7, the points which are on its graph is -5 and 7.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

To solve the inequality |x| + 3 > 7, we need to isolate the absolute value by subtracting 3 from both sides, and then split it into two cases -

|x| > 4 and -(|x|) > 4 (by multiplying both sides by -1)

Simplifying the second inequality, we get -

|x| < -4

But this is impossible, because the absolute value of any number is always non-negative.

Therefore, the second inequality has no solutions.

For the first inequality, we have -

|x| > 4

This means that x is either less than -4 or greater than 4.

Therefore, the points on the graph that satisfy the inequality are -

-5 and any value less than -4

Any value greater than 4

So the points on the graph that satisfy the inequality are -

-5 and any value less than -4 or greater than 4.

Therefore, the correct options are -

-5 and 7.

How to determine the table of values and graph

From the question, we have the following parameters that can be used in our computation:

y < |4x + 1| - 3

To create a table of values for y < |4x + 1| - 3, we can choose different values of x and substitute them into the expression to find the corresponding values of y.

Let's choose some values of x: -2, -1, 0, 1, 2.

When x = -2, we have:

y < |4(-2) + 1| - 3

y < 4

When x = -1, we have:

y < |4(-1) + 1| - 3

y < 0

When x = 0, we have:

y < |4(0) + 1| - 3

y < |1| - 3

Use the image to determine the direction and angle of rotation.



90° clockwise rotation
270° clockwise rotation
90° counterclockwise rotation
180° counterclockwise rotation

Answers

After comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

What is meant by the rotation of figures?

A transformation known as a rotation involves turning the figure either clockwise or counterclockwise. The centre of rotation is the fixed location where the rotation occurs. The term "angle of rotation" refers to the amount of rotation. A figure can be rotated 90 degrees, or a quarter turn, in either a clockwise or counterclockwise direction. You have rotated the figure 180 degrees when you have spun it exactly halfway. The figurine may be rotated 360° by turning it all the way around. A counterclockwise turn has a positive magnitude because a clockwise rotation indicates a negative magnitude. Rotational symmetry exists in every regular polygon. When an object is rotated around its centre, it retains its original appearance. The object is then referred regarded as having rotational symmetry.

Let's write the coordinates of the original figure,

A = (1, -5)

B = (6, -2)

C = (6, -5)

D = (1, -8)

Now, if we rotate it 90 degrees counterclockwise, the coordinates are:

A' = ( 5, 1)

B' = (2, 6)

C' = (5, 6)

D' = (8, 1)

Now if we rotate it again 90 degrees counterclockwise, the coordinates are:

A'' = ( -1, 5)

B'' = (-6, 2)

C'' = (-6, 5)

D'' = (-1, 8)

Now from the figure, let's write the coordinates.

A' = ( -1, 5)

B' =  (-6, 2)

C' = (-6, 5)

D' =  (-1, 8)

This is the same as the coordinates of the second 90 degrees counterclockwise rotation.

Since we did two 90 degrees rotations, we can say we did a total of 180° counterclockwise rotation.

Therefore after comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

At a carnival game, it cost Taylor $6 to toss 63 rings. Fill out a table of equivalent ratios and plot the points on the coordinate axes provided.

Answers

Graph is the collection of all points whose coordinates satisfy a given relation (such as a function).

What is coordinates?

Coordinates of a point in a 2D plane, also known as cartesian coordinates, are two numbers or sometimes a combination of a letter and a number that tell us the exact location of a specific point on a grid. Here, the grid is known as a coordinate plane.

Let tosses be x and and dollars be y

Then we have, (x, y) as (63, 6)

So if in 6 dollars you get 63 tosses then 1 dollar you get = 63/6 = 10.5 tosses.

Then in 2 dollars we have = 10.5 × 2 = 21 tosses

As 21 tosses = 2 dollars

Then 42 tosses = 2 × 2 = 4 dollars

Thus, we have the table:

[tex]\boxed{\begin{array}{cc}\underline{\text{Tosses}}&\underline{\text{dollars}}&\\ \boxed{10.5}&2&\\42&\boxed4&\\63&6&\end{array}}[/tex]

To graph the given points, just correspond x as tosses and y as dollars.

7-5 skills practice parts of similar triangles

Answers

The answer is (1) x = 22.5; (2) x = 16.7; (3) x = 13.5; (4) x = 16.8; (5) x = 24.5; (6) x = 16.15; (7.a) height of the image on film is 11.2mm; (7.b) distance between camera and her friend is 1,875mm.

(1) We can see that in the given figure all three corresponding angles are congruent and all three corresponding sides are in equal proportion so, these are similar triangles.

As per properties of similar triangle:

Three pairs of corresponding sides are proportional i.e. Two pairs of corresponding sides are proportional and the corresponding angles between them are equal.

                        Therefore, [tex]\frac{32}{24} =\frac{30}{x}[/tex],

then by cross multiplying them, we get,

                                        32x = 720

                                            x = 720/32

                                           x = 22.5

(2) As, this is already given that these are similar triangle and by applying the properties of similar triangle we get,

                                           [tex]\frac{39}{26} =\frac{25}{x}[/tex]

                                         39x = 650

                                             x = [tex]16\frac{2}{3}[/tex]

                                            x = 16.7

(3) As these are similar triangle again we can say that,

                                        [tex]\frac{2x+1}{x+4} =\frac{40}{25}[/tex]

                                 40(x + 4) = 25(2x + 1)

                                40x + 160 = 50x + 25

                                          40x = 50x - 135

                                          -10x = -135

                 (by cancelling (-) sign from both sides we get,

                                              x = 135/10

                                             x = 13.5

(4) By applying similar triangle's property, we can get

                                           [tex]\frac{20}{30} =\frac{28-x}{x}[/tex]

                                         20x = 840 - 30x

                                         50x = 840

                                             x = 840/50

                                             x = 16.8

                                            18x = 441

                                                x = 441/18

                                          6x = 96.6

                                            x = 96.6/6

                                            x = 16.15

(7.a) First we have to change 3 m and 140 cm into mm(millimeters).

So, 1m = 1000 mm

     3m = 3000mm.

And 1cm = 10 mm

   140cm = 1400 mm.

Then to find the height of the image on the film, we have to solve:

                                          [tex]\frac{24}{3000} =\frac{x}{1400}[/tex]

             by cross multiplication we get,

                                      3000x = 33,600

                                               x = 33,600/3000

                                              x = 11.2 mm

the height of the image on the film is 11.2millimeters.

(7.b) For this also, we have to find x by solving the equation:

                                            [tex]\frac{24}{3000} =\frac{15}{x}[/tex]

                                            24x = 45,000

                                                x = 45,000/24

                                              x = 1,875 mm

Answers

The solutions to the equation (w-2)^(2)-54=0 are w = 2, w = 9, and w = -6.

The equation (w-2)2 - 54 = 0 can be solved by factoring.


Let's start by writing the equation as: (w-2)(w-2) - 54 = 0

We can factor out (w-2) to get: (w-2)(w2 - 4w - 54) = 0

Now we can factor the second part of the equation, by splitting the middle term (4w) to get: (w-2)(w-9)(w+6) = 0

Now we have three equations, which we can solve separately:


   

w - 2 = 0 → w = 2


   

w - 9 = 0 → w = 9


   

w + 6 = 0 → w = -6

Therefore, the solutions to the equation (w-2)2 - 54 = 0 are w = 2, w = 9, and w = -6.

Assume that y = f(x) is a rational function satisfying the following constraints: i. There is a x-intercept at x = 0, and the local approximation here is given by y = ii. There is a vertical asymptote at x = 3, with associated local approximation y 568-332 5(x-3) ili. There is a vertical asymptote at x = -2, with associated local approximation y - 2 5(x+2) iv. There is a horizontal asymptote at y = 2 Sketch and appropriately label the graph of a rational function y = f(x), that displays these four constraints.

Answers

The graph of the rational function y = f(x) is represented by the blue line on the graph above. The x-intercept is the point at which the function crosses the x-axis and is labeled (0, 0).

The vertical asymptote at x = 3 is the red line. The local approximation for the vertical asymptote at x = 3 is represented by the black line and is given by y = 568 - 332(x - 3). Similarly, the vertical asymptote at x = -2 is the purple line and the associated local approximation is given by y = -2(x + 2). Finally, the horizontal asymptote at y = 2 is the orange line.

To illustrate the graph, assume the function f(x) is the following: f(x) = (x + 2)(x - 3) / (x + 5). This function is a rational function, as it is the ratio of two polynomials, and it has the given constraints.


To graph the rational function, we begin by finding the x-intercept, which is (0, 0). Then, we look at the vertical asymptote. At x = 3, the local approximation is given by y = 568 - 332(x - 3). We solve the equation y = 568 - 332(x - 3) for x, and get x = 3, thus we mark this point on the graph as the vertical asymptote. We do the same for the vertical asymptote at x = -2 and mark this point on the graph. Finally, we draw the line for the horizontal asymptote at y = 2. This gives us the complete graph of the rational function y = f(x).


In conclusion, the graph of the rational function y = f(x) that displays the four constraints can be sketched and labeled as shown in the figure above.

Find the balance of a savings account after 212 years if the simple interest earned each quarter is 0. 35% and the principal is $450

Answers

A $450 principal and a simple interest rate of 0.35% each quarter for 212 years would result in a savings account balance of $3768.

Amount and simple interest

We can use the formula for simple interest to solve this problem:

Simple Interest = Principal x Rate x Time

where Rate is the interest rate as a decimal, and Time is the time in years.

The quarterly interest rate is 0.35% / 4 = 0.00875, and the time is 212 years, or 848 quarters.

Plugging in these values, we get:

Simple Interest = $450 x 0.00875 x 848 = $3318

Therefore, the balance of the savings account after 212 years would be:

Balance = Principal + Simple Interest = $450 + $3318 = $3768

On an analog clock, the hour hand rotates 30 degrees as the second hand rotates 21,600 degrees. Which equation correctly relates the variables defined below?

h: angular motion of the hour hand, in degrees

s: angular motion of the second hand, in degrees

Answers

Step-by-step explanation:

the ratio is 30/21600 = 3/2160 = 1/720

that means for every degree the hour hand moves, the second hand does 2 full rotations (2×360°).

h = s×30/21600 = s/720

FYI :

as there are 12 hours on a clock, every hour means 360/12 = 30° rotation for the hour hand.

so, for each hour the second hand moves 21600°.

that means 21600/360 = 60 full rotations.

that means one rotation of the second hand is 1 minute.

so, the second hand is truly a second hand (counting the seconds).

60 seconds in a minute (a full rotation by the second hand), that means each second corresponds to 360/60 = 6° rotation of the second hand.

Answers

We can conclude that the students did not have any time left to work on homework.

The duration of Mr. K's math class is 1 and 1/4 hours, or 5/4 hours.

We need to determine how much time is left for the kids to do their assignment after working on problems on the board for 55 minutes and 11/12 hours. To achieve this, we must take the time spent solving issues out of the overall class time:

Total class time = 5/4 hours

Time spent on working problems = 55 minutes + 11/12 hours

= (55/60) hours + (11/12) hours

= (11/12 + 55/60) hours

= (11/12 + 11/12) hours

= (22/12) hours

= (11/6) hours

Overall class time minus the amount of time spent solving problems equals the amount of time remaining for homework.

= 5/4 hours - 11/6 hours

= (15/12) hours - (22/12) hours

= (-7/12) hours

We can infer that the kids ran out of time to finish their homework because the response is illogical because we cannot have negative time.

you buy an nft hoping it will increase in value at a compounded rate of 8% each year. if you pay $500 for the nft now. how much do you expect it to be worth in 20 years?

Answers

Using cοmpοund interest , the tοtal wοrth after 20 years is $2,330.48.

What is cοmpοund interest?

The interest that is calculated using bοth the principal and the interest that has accrued during the previοus periοd is called cοmpοund interest. It differs frοm simple interest in that the principal is nοt taken intο accοunt when determining the interest fοr the subsequent periοd with simple interest.

Here the principal P= $500

Rate οf interest r = 8%

Number οf years = 20 years,

Nοw using cοmpοund interest fοrmula then,

=> Total amount = [tex]P(1+\frac{r}{100})^t[/tex]

=> A = [tex]500(1+\frac{8}{100})^{20}[/tex]

=> A = [tex]500(1+0.08)^{20}[/tex]

=> A = [tex]500(1.08)^{20}[/tex]

=>A = $2,330.48

Hence after 20 years , nft's total worth is $2,330.48.

In a Poisson distribution with µ = 7
a. What is the probability that x = 10?
b. What is the probability that x > 5?

Answers


a. The probability that x=10 in a Poisson distribution with µ = 7 is 0.0942.
b. The probability that x > 5 in a Poisson distribution with µ = 7 is 0.4790.

A discontinuous probability distribution is a Poisson distribution. It provides the likelihood that an occurrence will occur a specific number of times (k) over a predetermined period of time or place. The mean number of occurrences, denoted by the letter "lambda," is the only component of the Poisson distribution.

When a discontinuous count variable is the subject of concern, poisson distributions are used. Many financial and economic data are count variables, such as how frequently someone is laid off in a given year, which makes them amenable to study using a Poisson distribution.

Amna needs to make a total of 95 deliveries this week. So far she has completed 57 of them. What percentage of her total deliveries has Amna completed

Answers

If Anna has 95 deliveries to make and has delivered 57, she has completed 60% of the total deliveries.

To find the percentage of deliveries that Amna has completed, we can use the formula:

percentage = (part/whole) × 100

So in this case, the part is the number of deliveries Amna has completed, which is 57, and the whole is the total number of deliveries she needs to make, which is 95. Plugging these values into the formula, we get:

percentage = (57/95) × 100 %

percentage = 0.6 × 100 %

percentage = 60 %

Therefore, Amna has completed 60% of her total deliveries.

Determine if the expression -a^(2)+b^(4)-7a^(3) is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.

Answers

The expression -a^(2)+b^(4)-7a^(3) is a polynomial.

A polynomial is a mathematical expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. The given expression satisfies all these conditions, and therefore, it is a polynomial.

The type of the polynomial is determined by the number of terms it has. In this case, the polynomial has 3 terms, so it is a trinomial.The degree of a polynomial is the highest exponent of the variable. In this case, the highest exponent is 4 (in the term b^(4)), so the degree of the polynomial is 4. Therefore, the expression -a^(2)+b^(4)-7a^(3) is a trinomial of degree 4.

Hi urgent I need help today is my birthday all I ask is for anyone to help me with mark h questions the subject is algebra two mode, median and mean please this is serious and a cry for help if your interested please let me know also please feel free to ask for time zone and anything else thank you
Brainly will be issued as well

Answers

Answer:

Step-by-step explanation:

I am definitely willing to help anyone with algebra!

It seems you need explanations on mode, median and mean. First, let's remember that these terms are related to data sets.

Example: I have a list of grades in Algebra 2, which list off as 94, 94, 95, 96, 98, 99, 99, 99, 99, 100.

I want the mode, median and mean. The mode is the number that appears the most in a data set, the median is the number in the exact middle of a data set, and the mean is the average value of the data set.

Mode: The number that appears most in this list of grades is 99. My mode is 99, and usually people use this to represent the whole of a data set, especially when the mode appears in the majority of the data set, at least 80% of the data set.

Median: My median is basically the number in the middle of the list. Since I have an even number of 10 grades, I need to find the two numbers closest to the middle, which is 98 and 99, the fifth and sixth term. I find the average of these two numbers- (98+99)/2 = 98.5. This is my median grade. This is usually used to represent data sets when describing demographics.

Mean: This is the average of the whole data set, which means we add up all the numbers and divide them by the number of items there are. Since we have ten grades in the data set, I add (94+94+95+96+98+99+99+99+99+100)/10 = 97.3

This is my mean, which represents my average grade. The mean is used a lot when teachers create our report cards! Hope this helps, but if you need anything else, feel free to comment back on this.

25 Points Use Bisection Method to locate the root of f(x) = x/3 + In(x) - 1 on a closed interval [1,2]. Use 17 iterations to extract the root.

Answers

The Bisection Method is a numerical method used to find the roots of a function within a given interval. It works by repeatedly dividing the interval in half and checking which half contains the root until the desired level of accuracy is achieved. In this case, we are using 17 iterations to extract the root of the function f(x) = x/3 + In(x) - 1 on the closed interval [1,2].

To locate the root of f(x) = x/3 + In(x) - 1 on a closed interval [1,2] using the Bisection Method with 17 iterations, we will follow the steps below:

1. Define the function f(x) = x/3 + In(x) - 1
2. Set the initial values for the interval: a = 1 and b = 2
3. Start the iteration process by finding the midpoint of the interval: c = (a+b)/2
4. Evaluate the function at the midpoint: f(c) = f((a+b)/2)
5. Determine if the root lies in the left or right half of the interval by checking the sign of f(c)
6. If f(c) is positive, then the root lies in the left half of the interval, so we set b = c and repeat the process from step 3.
7. If f(c) is negative, then the root lies in the right half of the interval, so we set a = c and repeat the process from step 3.
8. Continue the iteration process until we have completed 17 iterations.

After 17 iterations, we will have narrowed down the interval to a very small range and the midpoint of this interval will be an approximation of the root of the function.

2x3+3x2-12x+5 criterio de la primera derivada

Answers

Answer:

To apply the first derivative test to the function f(x) = 2x^3 + 3x^2 - 12x + 5, we need to find its derivative:

f'(x) = 6x^2 + 6x - 12

Then, we need to find the critical points by solving for f'(x) = 0:

6x^2 + 6x - 12 = 0

Dividing both sides by 6, we get:

x^2 + x - 2 = 0

Factoring the left side, we get:

(x + 2)(x - 1) = 0

So the critical points are x = -2 and x = 1.

To determine the intervals where f(x) is increasing and decreasing, we need to evaluate f'(x) on each side of the critical points. We can use a sign chart to do this:

x     |  -2  |  1  |

------|-----|----|

f'(x) | -12 |  0 |

Since f'(x) is negative to the left of x = -2 and positive to the right of x = -2, the function is decreasing to the left of x = -2 and increasing to the right of x = -2. Since f'(x) changes sign at x = 1, there is a local minimum at x = 1.

Therefore, using the first derivative test, we can conclude that the function has a local minimum at x = 1.

Answers

The car travels 4 feet in 1 second, 16 feet in 4 seconds, 24 feet in 6 seconds, 32 feet in 8 seconds.

Describe Distance?

Distance is a measure of the amount of space between two objects or points. It is the length of the shortest path between the two points, and it is typically measured in units such as meters, kilometers, miles, or feet.

In mathematics, distance is often calculated using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The car travels 4 feet in 1 second, which is equivalent to a rate of 4 feet per second.

The car also travels 16 feet in 4 seconds, which is also equivalent to a rate of 4 feet per second.

Similarly, the car travels 24 feet in 6 seconds, 32 feet in 8 seconds, and so on, all at a constant rate of 4 feet per second.

A watch was bought for 2,700 including 8% VAT. Find its price before the VAT was added.

Answers

Answer:

Let's assume that the price before adding the VAT is x.

We know that the VAT rate is 8%, which means that the VAT amount is 8% of x, or 0.08x.

The total price including VAT is the sum of the price before VAT and the VAT amount, so we can write:

Total price = price before VAT + VAT amount

or

2,700 = x + 0.08x

Simplifying this equation, we can combine like terms on the right-hand side to get:

2,700 = 1.08x

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 1.08:

x = 2,700 / 1.08

x = 2,500

Therefore, the price before VAT was added is 2,500.
