find the slope of the line that contains each pair of points (2,6) and (0,1)

Answers

Answer 1

5/2 is the slope of line .

What is slope, exactly?

Typically, a line's slope provides information about the steepness and direction of the line. Finding the difference between the coordinates of the locations will allow you to quickly compute the slope of a straight line connecting two points, (x1,y1) and (x2,y2).

                           The letter "m" is frequently used to signify slope. A line's steepness can be determined by its slope. In mathematics, slope is calculated as "rise over run" (change in y divided by change in x).

Answers

The probability that X is greater than 1 is less than or equal to 0.5, making the correct answer (C) 0.5.

Markov's inequality states that for a non-negative random variable X and a positive number a, the probability that X is greater than a is less than or equal to the expected value of X divided by a. In mathematical terms, this can be written as:

P(X > a) ≤ E(X) / a

In this case, X follows an exponential distribution with a mean of 1/2.0, or 0.5. Therefore, the expected value of X is 0.5. If we plug in the values for X and an into Markov's inequality, we get:

P(X > 1) ≤ 0.5 / 1

Let's represent the vοlume οf jug A by x and the vοlume οf jug B by y.

We knοw that the cοmbined vοlume οf the twο jugs is 800 ml:

x + y = 800 (equatiοn 1)

We alsο knοw that after pοuring water frοm jug A tο jug B, there is 200 ml οf water remaining in jug A. This means that jug B cοntains x ml οf water:

y = x (equatiοn 2)

We can substitute equatiοn 2 intο equatiοn 1 tο eliminate y:

x + y = 800

x + x = 800

2x = 800

x = 400

Nοw that we knοw that the vοlume οf jug A is 400 ml, we can use equatiοn 2 tο find the vοlume οf jug B:

y = x

y = 400

Therefοre, the vοlume οf jug B is alsο 400 ml.

Answers

Question Number 5.

The first and second numbers in the exponential sequence are 10 and 5, respectively.

How do we solve this?

In the exponential sequence given by a, b, c, d, ..., where a and b are the first two numbers. We know that the third number is given by b * c/a, and the fourth number is given by c * d/b.

the third number = 100

the fourth number = 500,

So b * c/a = 100

c * d/b = 500

rearranging the first equation :

c = 100a/b

Substituting this into the second equation, we then have

d = 500b/a

The sequence is then written as a, b, 100a/b, 500b/a, ...

We then proceed to  find a and b,

a, b, 100a/b, 500b/a, ...

a, b, 100a/b, 500b/a, ... = a, b, 100a/b, 500b/a, ...

100a/b = 100

500b/a = 500

Solving for a and b, we have:

a = 10

b = 5

In conclusion, the first and second numbers in the exponential sequence  are 10 and 5.

Using remainder theorem, find the value of k if on dividing 2x3+3x2−kx+5 by x−2, leaves a remainder 7

Answers

The value of k is 13.

Using the remainder theorem, we can find the value of k by substituting the value of x in the given polynomial equation with the value that makes the divisor equal to zero. In this case, the divisor is x-2, so the value of x that makes it equal to zero is x=2.

Substituting x=2 into the polynomial equation, we get:

2(2)^3 + 3(2)^2 - k(2) + 5 = 7

Simplifying the equation, we get:

16 + 12 - 2k + 5 = 7

33 - 2k = 7

Alexia took out a 12-year loan for $72,000 to renovate her home. If her monthly payments are $680, what is the interest rate?

Answers

Answer:

Finding the total accrued amount is necessary before we can determine the interest rate.

Simply multiplying the monthly payment by the number of months in a 12-year period will give us the accrued amount.

144 months in 12 years.

$680 x Monthly Payment

A = 680 * 144

A = $97920

We can use the following formula now that we know the total accrued sum:

A= 97920

P = 72000

t= 12

Let's replace them with our values now.

The percentage value is then obtained by multiplying the r value by 100.

0.03 x 100 = 3%

The interest rate for Alexia is 3%.

Answers

It is possible for each of the six quadratic equations to have at least one real root.

This is because the discriminant of a quadratic equation determines the nature of its roots. The discriminant is given by the formula: D = b² - 4ac.

If D > 0, the equation has two distinct real roots.
If D = 0, the equation has one real root (a double root).
If D < 0, the equation has no real roots (two complex roots).

In each of the six equations, the coefficients a, b, and c are non-zero real numbers. This means that the discriminant can be positive, zero, or negative, depending on the values of a, b, and c. Therefore, it is possible for each of the six equations to have at least one real root.

For example, consider the equation ax² + bx + c = 0. If b² > 4ac, then the equation has two distinct real roots. If b² = 4ac, then the equation has one real root (a double root). If b² < 4ac, then the equation has no real roots (two complex roots).

Similarly, the other five equations can also have at least one real root, depending on the values of the coefficients a, b, and c.

There are two solutions to the equation 1/(1 - x²) = -|3x - 2| + 5.

What is Equation?

An equation is a statement that shows that two mathematical expressions are equal to each other. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponents.

We can start by considering the case where the expression inside the absolute value is non-negative, i.e., 3x - 2 ≥ 0, which implies x ≥ 2/3. In this case, the equation becomes:

1/(1 - x²) = 3x - 2 + 5

1/(1 - x) = 3x + 3

Multiplying both sides by 1 - x², we get:

1 = (3x + 3)(1 - x²)

3x³ + x² - 3x - 2 = 0

This equation has one real root.

The root is approximately x = 0.727.

Next, we consider the case where the expression inside the absolute value is negative, i.e., 3x - 2 < 0, which implies x < 2/3. In this case, the equation becomes:

1/(1 - x²) = -(3x - 2) + 5

Simplifying this equation, we get:

1/(1 - x) = -3x + 3

1 = (-3x + 3)(1 - x²)

3x³ - x² - 3x + 2 = 0

This equation also has one real root, which we can find using the same methods as before. The root is approximately x = -0.727. \

Therefore, there are two solutions to the equation 1/(1 - x²) = -|3x - 2| + 5.

"Find the total price: Total bill: $45.65 Tip: 22% Tax: 5%"

Answers

Answer:

To find the total price, we need to add the tip and tax to the total bill amount.

First, we need to find the amount of the tip. To do this, we will multiply the total bill by 22% (or 0.22):

$45.65 x 0.22 = $10.04

This means the tip amount is $10.04.

Next, we need to find the amount of tax. To do this, we will multiply the total bill by 5% (or 0.05):

$45.65 x 0.05 = $2.28

This means the tax amount is $2.28.

Finally, we can find the total price by adding the total bill, tip, and tax together:

$45.65 + $10.04 + $2.28 = $57.97

Therefore, the total price is $57.97.

What is an equation to model the relationship between the height, in centimeters, and the age, in years, of this child?

We may use linear regression to construct an equation that represents the link between this child's height and age. The line of best fit for the supplied data is determined by linear regression, which can be written as:

Age (years) + b * m * Height (cm)

where m denotes the line's slope and b its y-intercept.

The equation that most closely matches the above data can be determined using a calculator or spreadsheet software as follows:

Age (years) + 72.66 Height (cm) = 6.087

Points A and B have coordinates (-5, 16) and (3,12) respectively.
C is the point that lies of the way along AB. Find the coordinates of C.

Answers

Answer:

the coordinates of point C are approximately (0.56, 17.72)

Step by step Explanation:

To find the coordinates of point C, we need to find its distance from point A as a fraction of the distance between points A and B, and then use that fraction to find the coordinates of C.

Let's call the distance between points A and B "d". We can find the distance using the distance formula:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) and (x₂, y₂) are the coordinates of points A and B, respectively. Plugging in the values, we get:

d = √[(3 - (-5))² + (12 - 16)²] = √64 + 16 = √80

Now, let's call the fraction of the distance from A to B that C lies on "f". We know that C is closer to A than to B, so 0 ≤ f ≤ 1. We can find f using the formula:

f = AC/AB

where AC is the distance from A to C. We can use the distance formula again to find AC:

AC = √[(x - (-5))² + (y - 16)²]

where (x, y) are the coordinates of point C. We also know that C is on the line segment AB, so its x-coordinate must satisfy:

(x - (-5))/(3 - (-5)) = f

Simplifying, we get:

(x + 5)/8 = f

Solving for x, we get:

x = 8f - 5

Similarly, we can use the y-coordinate of C to form another equation:

(y - 16)/(12 - 16) = f

Simplifying and solving for y, we get:

y = 4(1 - f) + 16 = 20 - 4f

Now we have expressions for x and y in terms of f. We can substitute these into the expression for AC:

AC = √[(8f - 5 - (-5))² + (20 - 4f - 16)²] = √[64f² - 64f + 100]

Finally, we can plug in our expressions for AC and AB to solve for f:

f = AC/AB = √[64f² - 64f + 100]/√80

Squaring both sides and simplifying, we get a quadratic equation:

64f² - 64f + 100 = 80f²

16f² + 64f - 100 = 0

Dividing both sides by 4 and using the quadratic formula, we get:

f = (-64 ± √(64² - 4(16)(-100))) / 2(16)

f ≈ -0.32 or f ≈ 1.57

Since 0 ≤ f ≤ 1, the valid solution is:

f ≈ 0.57

Now we can use this value to find the coordinates of C:

x = 8f - 5 ≈ 0.56

y = 20 - 4f ≈ 17.72

Therefore, the coordinates of point C are approximately (0.56, 17.72)

Felipe makes a bracelet with 30 beads. The table shows the number of beads of
each color on the bracelet. Write 3 ratios to represent the number of beads (part-
part, part-part, and part-whole)

Answers

Other fractions could represent the part of the beads on the bracelet that will be green are : 1/3, 2/6, 3/9, 4/12.

What is fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

here, we have,

The maximum number of beads the bracelet can have  = 12 beads

The fraction of green beads in the bracelet = 1/3

⇒ 1 bead in every 3 bead is GREEN.

⇒The minimum number of total beads = Number of (green+ Other) bead                                                           = 2 + 1  = 3

Now, the possible number of total beads the bracelet can have is

3, 4, 5 , 6, 7, 8, 9 ,10, 11 and 12.

If there are total 3 beads, the fraction representing the green bead  = 1/3

If there are total 6( =3 +3) beads, the fraction representing the green bead  

= 1 green bead in first 3 beads +  1  green bead in next 3 beads

=   2 green beads in total 6 beads

=   2/6

If there are total 9( = 3 +3 +3) beads, the fraction representing the green bead  = 3/9

If there are total 12( = 3 +  3 +3 +3) beads, the fraction representing the green bead  = 4/12

Hence, other fractions could represent the part of the beads on the bracelet that will be green are :1/3, 2/6, 3/9, 4/12.

The value of the line segment AB of the trapezoid ABCD will be 25.9 units.

What is a trapezoid?

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.

The sum of the parallel sides of the trapezoid is equal to twice the line segment that divides the other two sides in the ratio of 1: 1.

Then the equation is given as,

MN = (AB + CD) / 2

18.7 = (AB + 11.5) / 2

37.4 = AB + 11.5

AB = 25.9 units

The value of the line segment AB of the trapezoid ABCD will be 25.9 units.

Write the given expression as a single trigonometric function. tan(3pi/7) - tan(2pi/5)/ 1+tan(3pi/7) tan(2pi/5)

Answers

On sοlving the given trigοnοmetric expressiοn using the trigοnοmetric identity, we fοund that it is equal tο tan (π/35).

What is an expressiοn?

Mathematical expressiοns cοnsist οf at least twο numbers οr variables, at least οne maths οperatiοn, and a statement. It's pοssible tο multiply, divide, add, οr subtract with this mathematical οperatiοn. A finite cοmbinatiοn οf symbοls that are well-fοrmed in accοrdance with cοntext-dependent principles is referred tο as an expressiοn οr mathematical expressiοn.

There are twο sοrts οf expressiοns in mathematics: numerical expressiοns, which οnly cοntain numbers, and algebraic expressiοns, which alsο include variables. Expressiοns can be categοrised as arithmetic/numerical expressiοns, fractiοnal expressiοns, οr algebraic expressiοns depending οn the terms they cοntain.

The given trigοnοmetric expressiοn is:

[tex]\frac{tan (3\pi /7) - tan (2\pi /5)}{1+tan (3\pi /7) tan (2\pi /5)}[/tex]

tan (a-b) = sin(a-b)  / cοs (a-b)

    = (sin a cοs b - cοs a sin b) / (cοs a cοs b + sin a sin b)

  Dividing the numeratοr and denοminatοr by (cοs a cοs b), we get,

tan (a-b) = (tan (a) - tan (b)) / (1+tan a tan b)

This expressiοn is similar tο the given expressiοn.

Cοmparing,

a = 3π/7

b = 2π/5

[tex]\frac{tan (3\pi /7) - tan (2\pi /5)}{1+tan (3\pi /7) tan (2\pi /5)}[/tex]  = tan( 3π/7 - 2π/5) = tan (π/35)

Therefοre on solving the given trigonοmetric expression using the trigonοmetric identity, we found that it is equal tο tan (π/35).
