Answer:

The rate of change of section A is 3 and rate of change of section B is 48.

Step-by-step explanation:

The given function is

[tex]h(x)=4^x[/tex]

Formula for average rate:

[tex]m=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

Section A is from x = 0 to x = 1, the average rate of change of section A is

[tex]m_1=\frac{h(1)-h(0)}{1-0}=\frac{4-1}{1}=3[/tex]

Section B is from x = 2 to x = 3, the average rate of change of section B is

[tex]m_2=\frac{h(3)-h(2)}{3-2}=\frac{64-16}{1}=48[/tex]

Therefore rate of change of section A is 3 and rate of change of section B is 48.

[tex]m_1\times k=m_2[/tex]

[tex]3\times k=48[/tex]

[tex]k=12[/tex]

Therefore average rate of change of Section B is 12 times of Section A.

The given function is an exponential function and rate of change is not constant.

Answer:

Option C It will cost $42 for 28 binders

Step-by-step explanation:

Mrs. Santos determined that 15 binders would cost = $22.50

Therefore, 1 binder would cost = $1.50

Now we calculate each statement :

a. 18 binders will cost $12

= 18 × $1.50 = $27.00 (not correct)

b. 30 binders will cost $20

= 30 × $1.50 = $60.00 (not correct)

c. 28 binders will cost $42

28 × $1.50 = $42.00 (Correct)

d. 48 binders will cost $48

48 × $1.50 = $72.00 (not correct)

Option C It will cost $42 for 28 binders would be correct.

If the graph has 1/3 length…

At least 20 minutes late: this would mean 20 minutes late or more.

20 or more minutes goes from 20 to 30. So that is a difference of 30 – 20 = 10. The distance of your rectangle is 10.

Length * width = (1/30) * 10 = 1/3 or 0.3333. The probability the friend is at least 20 minutes late is 0.3333.

Answer:

-5p-3

Step-by-step explanation:

use the distributive property

The measure of the third angle is 50 degrees for the given triangle. The correct answer would be an option (A).

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.

Let x be the measure of the third angle.

As we know that the sum of interior angles in the triangle is always 180 degrees.

So, as per the given question, we have

30° + 100° + x = 180°

130° + x = 180°

x = 180° - 130°

Apply the subtraction operation, and we get

x = 50°

Thus, the measure of the third angle is 50 degrees.

The  quotient of −4 1/2 ÷ (−2 2/3) would be equal to  1 1/16 as a mixed number, in simplified form.

Quotients are the number that is obtained by dividing one number by another number. We can use the fact that division can be taken as multiplication but with the denominator's multiplicative inverse.

Thus,

[tex]\dfrac{a}{\frac{b}{c}} = a \times \dfrac{1}{\frac{b}{c} } = a \times \dfrac{c}{b} = \dfrac{a \times c}{b}[/tex]

We have been given that [tex]-4 \dfrac{1}{2}[/tex]  ÷ (-[tex]2 \dfrac{2}{3}[/tex])

But first convert the mixed fraction into simple fraction

[tex]-4 \dfrac{1}{2}[/tex]  = -9/2

(-[tex]2 \dfrac{2}{3}[/tex]) = -8/3

Thus, we have to divide the terms;

[tex]-4 \dfrac{1}{2}[/tex]  ÷ (-[tex]2 \dfrac{2}{3}[/tex])

-9/2 ÷  -8/3

-9/2 x -3/8

The area of the living room is approximately 238 square feet.

To find the area of the living room, we need to multiply its length by its width.

First, let's convert the dimensions from feet and inches to feet. We have:

Length: 12 feet + 4 inches = 12 + 4/12 = 12.33 feet

Width: 19 feet + 4 inches = 19 + 4/12 = 19.33 feet

Now, we can multiply the length and width to find the area:

Area = length × width = 12.33 feet × 19.33 feet = 238.1289 square feet

Rounding to the nearest whole square foot, the area of the living room is approximately 238 square feet.

Please help me with this problem.

The diagram shows the floor plan of a one-bedroom apartment. Find the area of the living room in square feet. Round to nearest square foot.

The dimensions of living room are 12' 4" x 19' 4"

On rounding off to nearest feet we get the area of the living room as 238 ft²

In the figure it is given that the dimensions of the living room are 12' 4" x 19' 4". This means that the dimensions are:

12 ft 4 in x 19 ft 4 in

To get the area in feet, we need to convert the dimensions into feet. This can be done by using the conversion factor that 1 foot = 12 inch

So, 12 ft 4 in can be converted into feet as follows:

[tex]12\ \text{ft}\ 4\ \text{in} = 12\ \text{ft}\ + \frac{4}{12}\ \text{ft} = 12.333\ \text{ft}[/tex]

19 ft 4 in can be converted into feet as follows:

[tex]19\ \text{ft}\ 4\ \text{in} = 19\ \text{ft}\ + \frac{4}{12}\ \text{ft} = 19.333\ \text{ft}[/tex]

Now to calculate the area we multiply the dimensions of the living room (as the living room is a rectangle and area of rectangle is product of its length and breadth):

[tex]area = 12.333 \times 19.333 =238.433889[/tex] ft²

On rounding of to nearest feet we get the area as 238 ft². So, the area of the living room is 238 ft²

Answer:

Step-by-step explanation:

Given is a scatter plot and the regression line using least squares.

We are required to find out how many more goals a player will score for every additional hour of practice.

In other words, we are to find the slope of the regression line.

By taking two points on the line we can find slope of the line.

(1.5,2) and (6.5,6) are points on the line

Find slope using two point formula

Slope = [tex]\frac{y2-y1}{x2-x1} =\frac{6-2}{6.5-1.5} \\=\frac{4}{5}[/tex]

near slope is 3/4

Hence answer is option b.

On average, the goals a player scores for every additional hour of practice will be 3/4.

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
