Answers

Answer 1

[tex]f(x) = x^{2} -5x + 12[/tex]

The graph of the function is a parabola true

____

The value of f(–10) = 82 → false

[tex]f(-10) = (-10)^{2} -5(-10) + 12 = 100+50+12 = 162 \neq 82\\[/tex]

The graph of the function opens down  → false The graph contains the point (20, –8) → false

[tex]f(20) = (20)^{2} -5(20) + 12 = 400-100+12 = 312 \neq - 8\\[/tex]

The graph contains the point (0, 0) → false

what is percentage ?

As a fraction of 100, a figure can be expressed as a percentage.  For instance, the decimal equivalent of 50% is 50/100 or 0.5. The comparison or representation of changes between two numbers is frequently done using percentages. For instance, a percentage increase or decline indicates how much something has changed from its starting point. Additionally, percentages are frequently used in daily contexts like interest rates, shopping discounts, and academic performance.

given

The formula below can be used to determine the percent reduction from 498 to 0:

(Original value - New value) / 100% of the original value equals the percent decline.

The initial number in this case was 498, and the updated value is 0.

Reduced percentage equals (498 - 0) / (498 x 100%)

How to find midsegment of a trapezoid?

The bases of a trapezoid have lengths of 6 feet and 10 feet. Let's find the length of the mid segment of the trapezoid.

A midsegment of a trapezoid is the line segment connecting the midpoints of the two non-parallel sides of a trapezoid.

The length of the midsegment of trapezoid is half the sum of the lengths of the two parallel sides

Hence,

mid segment = 1  /2 (6 + 10)

mid segment = 16 / 2

Answer:

The volume of the composite figure is 12,719 cm³ to the nearest whole number.

Step-by-step explanation:

The composite figure is composed of a cone and a half-sphere.

To calculate the volume of the figure, sum the volume of the cone and the volume of the half-sphere.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]     [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a half-sphere}\\\\$V=\dfrac{2}{3} \pi r^3$ \\\\ where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\\end{minipage}}[/tex]

Therefore, the equation for the volume of the composite figure is:

[tex]V=\dfrac{1}{3} \pi r^2 h+\dfrac{2}{3} \pi r^3[/tex]

From inspection of the given diagram:

d = 28 cmh = 34 cmπ ≈ 3.14

As the diameter of a circle is twice its radius, r = 14 cm.

Substitute the values of r, h and π into the equation and solve for V:

[tex]\begin{aligned}\implies V&=\dfrac{1}{3} \pi r^2 h+\dfrac{2}{3} \pi r^3\\\\&=\dfrac{1}{3} (3.14) (14)^2 (34)+\dfrac{2}{3} (3.14) (14)^3\\\\&=\dfrac{1}{3} (3.14) (196) (34)+\dfrac{2}{3} (3.14) (2744)\\\\&=6974.98666...+5744.10666...\\\\&=12719.09333...\\\\&=12719\;\sf cm^3\;\;(nearest\;whole\;number)\end{aligned}[/tex]

The shape of the distribution of the time to get an oil change is 15 minute oil change factory is unknown. However records indicate that the mean time is 16.9 and the standard deviation is 4.7 minutes Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical
Saturday, the oil-change facility will perform 40 oil changes between 10 A.M. and 12 P.M. Treating this as a random
sample, at what mean oil-change time would there be a 10% chance of being at or below? This will be the goal
established by the manager.
There would be a 10% chance of being at or below minutes.
(Round to one decimal place as needed.)

Answers

The mean oil-change time for which there is a 10% chance of being at or below is approximately 15.92 minutes.

What is the mean oil-change time?

We can start by using the Central Limit Theorem.

Data given:

The population mean is μ = 16.9 minutes

population standard deviation is σ = 4.7 minutes

sample size of n = 40 oil changes performed between 10 A.M. and 12 P.M.

The standard error of the mean (SE) is given by:

SE = σ / √n

SE = 4.7 / √40

SE = 0.743

To find the mean oil-change time for which there is a 10% chance of being at or below, we need to find the z-score associated with the 10th percentile of the standard normal distribution, which is -1.28 (using a standard normal distribution table or calculator).

We can use the formula for a z-score:

z = (x - μ) / SE

where x is the desired mean oil-change time.

Substituting the known values and solving for x, we get:

-1.28 = (x - 16.9) / 0.743

x = -1.28 * 0.743 + 16.9

x = 15.92

What is link between the diameter and radius of a circle?

A circle's diameter and radius are connected because the diameter is twice as long as the radius. Mathematically, this connection may be written as d = 2r, where d stands for the diameter and r for the radius. On the other hand, we can alternatively state that the radius is equal to half the diameter's length: r = d/2

The circumference of a circle can be found using the formula:

C = πd

Given that,

The kettle in Keith,s kitchen is 80% full. After 20% of the water in it has been poured out. There are 1152ml of water left. What volume of water does Keith’s kitchen kettle hold when it is full?

Answers

The volume of water that Keith's kitchen kettle holds when it is full is 1800 ml.

Assume that Keith's kitchen kettle has a "x" ml capacity when it is full.

The kettle is initially 80% full, which means it holds 0.8x ml of water, according to the problem.

20% of the water is poured out, leaving 80% of the original amount of water in the kettle, which is:

0.8x * 0.8 = 0.64x ml

We are informed that the 1152 ml of water that is left equates to:

0.64x = 1152

By multiplying both sides by 0.64, we obtain:

x = 1800

Consequently, Keith's cooking kettle has an 1800 ml capacity when it is full.

What is a sample?

A sample is characterised as a more manageable and compact version of a bigger group. A smaller population that possesses the traits of a bigger group. When the population size is too big to include all participants or observations in the test, a sample is utilised in statistical analysis.

The sample space for spinning the spinner two times can be found by listing all possible outcomes of the two spins.

Each spin has three possible outcomes, so the total number of outcomes for two spins is 3 x 3 = 9.

One way to list the sample space is to use a table where the rows and columns represent the outcomes of the first and second spins, respectively.

The entries in the table represent the ordered pairs of outcomes, with the first entry corresponding to the first spin and the second entry corresponding to the second spin.

Using this method, the sample space for spinning the spinner two times is -

Blue | Blue | (Blue, Blue) | Blue | Orange | (Blue, Orange) | Blue | Red | (Blue, Red)

Red | Blue | (Red, Blue) | Red | Orange | (Red, Orange) | Red | Red | (Red, Red)

Orange | Blue | (Orange, Blue) | Orange | Orange | (Orange, Orange) | Orange | Red | (Orange, Red)

Alternatively, we can list the outcomes as an unordered set of two elements, where the order of the elements does not matter.

In this case, the sample space for two spins would be -

{Blue, Orange} {Blue, Red} {Orange, Red}

{Blue, Blue} {Red, Blue} {Orange, Blue}

{Red, Red} {Orange, Orange}

The growth rate of the plant shown in the graph is 1/2 centimeter per week

Calculating the growth rate of the plant in the graph

From the question, we are to determine the growth rate of the plant

To determine the growth rate of the plant, we will determine the slope of the line

To determine the slope of the line passing through the points (1, 1/2) and (3, 1 1/2), we can use the slope formula:

Slope = (Change in y) / (Change in x)

We first calculate the change in y by subtracting the y-coordinate of the first point from the y-coordinate of the second point:

Δy = 1 1/2 - 1/2 = 1

Next, we calculate the change in x by subtracting the x-coordinate of the first point from the x-coordinate of the second point:

Δx = 3 - 1 = 2

Finally, we can calculate the slope by dividing the change in y by the change in x:

Slope = Δy / Δx = 1 / 2

The slope of the line is 1/2.

Hence, the growth rate is 1/2 centimeter per week

The greatest possible distance between two points on the walls in the room is 17 feet.

Step-by-step explanation:

The room can be modelled as a rectangular prism with the following dimensions:

width = 8 ftlength = 12 ftheight = 9 ft

The greatest possible distance between two points on the walls in the room is the line between diagonally opposite corners. This is marked as the blue line (x) on the attached 3D diagram.

This distance is the hypotenuse of a right triangle with a base of the diagonal of the floor and a height of the height of the room.

The diagonal of the floor (marked "y" on the attached diagram) is the hypotenuse of a right triangle with legs of the width and length of the room.  To calculate the diagonal of the floor, use Pythagoras Theorem.

Therefore, the diagonal of the floor (y) is √(208) feet in length.

We can now use Pythagoras Theorem again to find the length x.

Substitute a = y, b = 9 and c = x into the formula:

[tex]\implies y^2+9^2=x^2[/tex]

Substitute the found value of y and solve for x:

[tex]\implies (\sqrt{208})^2+9^2=x^2[/tex]

[tex]\implies 208+81=x^2[/tex]

[tex]\implies 289=x^2[/tex]

[tex]\implies x=\sqrt{289}[/tex]

[tex]\implies x=17 \sf \; ft[/tex]

Therefore, the greatest possible distance between two points on the walls in the room is 17 feet.

London deposits $100 into a savings account that pays a simplete ineterest rate of 3.4%. Chen deposits $200 into a savings account that pays a simple interest rate of 2.2%. Lodon says that she will earn more interest in one year because her interest rate is higher than Pablo's.

Answers

According to the given values London's statement is incorrect.

What is Simple Interest?

Simple interest is a type of interest that is calculated based on the principal amount of a loan or investment and the length of time for which the money is borrowed or invested. It is called "simple" because the interest is calculated only on the initial principal amount and does not take into account any interest that may have accrued in previous periods.

Let's calculate the interest earned by each person after one year:

London:

The amount deposited by London is $100. The simple interest rate is 3.4%. Therefore, the interest earned by London after one year is:

[tex]$$\text{Interest}[/tex] = [tex]\text{Principal} \times \text{Rate} \times \text{Time}[/tex] = [tex]$100 \times 3.4%[/tex] [tex]\times 1[/tex]= [tex]$3.40$$[/tex]

Chen:

The amount deposited by Chen is $200. The simple interest rate is 2.2%. Therefore, the interest earned by Chen after one year is:

[tex]$$\text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time}[/tex]= [tex]$200 \times 2.2%[/tex] [tex]\times 1[/tex] = [tex]$4.40$$[/tex]

As we can see, even though London's interest rate is higher than Chen's, Chen will earn more interest in one year because he deposited a larger amount of money.

Therefore, according to the given values London's statement is incorrect.

Solving Equation with Root and Power. Can someone please step by step explain how to solve this problem please?

Answers

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

First, square both sides.

[tex]\left(\sqrt{3+\dfrac{\left(4 + \sqrt{x+3} \, \right)^2}{6}}\, \right)^2= 3^2[/tex]

[tex]3+\dfrac{\left(4 + \sqrt{x+3} \, \right)^2}{6} = 9[/tex]

This eliminates the square root over the entire left side of the equation.

Next, multiply both sides by 6 to get rid of the fraction on the left side.

[tex]6\left(3+\dfrac{\left(4 + \sqrt{x+3} \, \right)^2}{6}\right) = 6( 9)[/tex]

[tex]6(3) + \left(4 + \sqrt{x+3} \, \right)^2 = 6(9)[/tex]

[tex]18 + \left(4 + \sqrt{x+3} \, \right)^2 = 54[/tex]

Then, subtract 18 from both sides to isolate the squared term.

[tex]18 + \left(4 + \sqrt{x+3} \, \right)^2 = 54\\\underline{-18 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \: } \ \ \ \ \ \underline{ - 18}[/tex]

[tex]\left(4 + \sqrt{x+3} \, \right)^2 = 36[/tex]

Now, we can square root both sides.

[tex]\sqrt{\left(4 + \sqrt{x+3} \, \right)^2} = \sqrt{36}[/tex]

[tex]4 + \sqrt{x+3} = \pm 6[/tex]

Remember to use apply the even root property, so that the right side (6) is positive or negative (indicated by the plus or minus sign).

Next, subtract 4 from both sides.

[tex]4 + \sqrt{x+3} = \pm 6 \\ \underline{-4\ \ \ \ \ \ \ \ \ \ \: } \ \ \ \ \ \underline{ - 4}[/tex]

[tex]\sqrt{x+3} = \pm 6 - 4[/tex]

Then, square both sides to get rid of the square root on the left side.

[tex]\left(\sqrt{x+3}\right)^2 = (\pm 6 - 4)^2[/tex]

[tex]x+3 = 2^2[/tex]    OR    [tex]x+3 = (-10)^2[/tex]

We can see that there are two resulting expressions, each of which we can solve individually.

[tex]x+3 = 4[/tex]    OR    [tex]x+3 = 100[/tex]

[tex]\boxed{x = 1}[/tex]                 [tex]\boxed{x\ne97}[/tex]

The reason that x = 97 is crossed out is because when we plug that x-value back into the original equation, it does not come out to be true. Therefore, 97 is an extraneous solution.

Also, see the attached image for another solution (that implores another method).

Answer:

  x = 1

Step-by-step explanation:

You want to solve for x:

  [tex]\sqrt{3+\dfrac{(4+\sqrt{x+3})^2}{6}}=3[/tex]

Solution

At any stage where there is a root, you isolate the radical and raise both sides of the equation to a power sufficient to eliminate the radical. Repeat as necessary.

Outer radical

The radical is already on one side of the equation by itself, so we simply square both sides:

  [tex]3+\dfrac{(4+\sqrt{x+3})^2}{6}=9\\\\(4+\sqrt{x+3})^2=6^2\qquad\text{subtract 3, multiply by 6}\\\\|4+\sqrt{x+3}|=6\qquad\text{take the square root}[/tex]

Inner radical

At this point, we note that the sum cannot be negative, so the absolute value bars are irrelevant. Isolating the radical and squaring both sides, we can finish the solution.

  [tex]4+\sqrt{x+3}=6\\\\\sqrt{x+3}=2\qquad\text{subtract 4}\\\\x+3=4\qquad\text{square both sides}\\\\\boxed{x=1}\qquad\text{subtract 3}[/tex]

This is the only solution, as the attached graph shows.

Additional comment

Generally, the square root symbol means the positive square root. That is, √z is usually considered to be non-negative.  This is why we use ±√z when we want both signs of the root.

In this problem, the only root we're taking as part of the solution is the root of a square. The possibility of a negative value for the term being squared is handled by using the absolute value brackets: √(z²) = |z|.

For solving these using a graphing calculator, we like to rewrite the equation to the form f(x)=0. That way, the solutions are the x-intercepts.

Answer:

1 buck

Step-by-step explanation:

Alright man im not a pro at this, so im not gonna have a professional explanation, but the final answer will be correct.

So listen up a dice has 6 sides labeled 1,2,3,4,5,6

3 of those are even

3 of those are odd

so you have a 50% chance of landing on an evan numbered side

and a 50% chance of landing on an odd-numbered side

So basically, if we play one round, there are 2 possibilities. We get even and win 2 bucks, or we get odd and lose a buck. We dont need to worry about probability as they are both 50%. Therfore, the value is 2-1 = 1 dollar. I found the value by subtracting the possbilities.
