Answer:

D. 25%

Step-by-step explanation:

Each day, Julia's sales are 1.25 times the previous day's sales. That is, 25% more than the day before. Julia's sales are increasing 25% per day.

ANSWER:

The correct answer is D.25%

STEP-BY-STEP EXPLANATION:

f(x) = 2 * (1.25)^x

This is in the form

y = a b^x

where b is 1 plus the growth rate

b = 1.25 = 1+growth rate

1.25 = 1 + growth rate

.25 = growth rate

25% = growth rate

The distance between points (3, 7) and (x₁, y ) is the square root of (x₁ - 3)² + (y₁ - 7)².

nasty-shy [4]

Based on the distance formula, the distance between points (3, 7) and (x1, y) is: $\sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}$ . SO, it is TRUE.

<h3>What is the Distance Formula?</h3>

The distance formula which can be applied to find the distance between two coordinate points is: $d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$ .

Given the points:

(x1, y1)

(3, 7) = (x2, y2)

Substitute

$d = \sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}$

Therefore, the statement that says the distance between points (3, 7) and (x1, y) = $\sqrt{(x_1 - 3)^2 + (y_1 - 7)^2}$ , is TRUE.

Suppose you are going to graph the data in the table below. What data should be represented on each axis, and what would be the

vlabodo [156]

The given table is representing Profits for the given years. The independent variable is represented on x axis and on y axis dependent variable is taken .Years of increment is the independent variable and profit is the dependent variable .Year is represented on the x axis while profit will be represented on y axis. The appropriate profit in increments is $50,000

Among all the given options Option a)x-axis: years in increments of 1; y-axis: profit in increments of $50,000 is the correct answer.

Oksi-84 [34.3K]

Answer:

9x/4= -9

Mutiply by 4 for both sides.

4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36

9x= -36

Divide by 9 for both sides

9x/9= -36/9

x= -4

The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1?

gulaghasi [49]

Answer:

The average rate of change of the function is: 0

Step-by-step explanation:

The function y = f(x) is graphed below.

From the graph it is clear that:

at x = -8, the value of f(-8) = -10

at x = -1, the value of f(-1) = -10

We have to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.

at x₁ = -8, f(x₁) = f(-8) = -10

at x₂ = -1, f(x₂) = f(-1) = -10

Using the formula to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

= [f(-1) - f(-8) ] / [-1-(-8)]

= [-10 - (-10)] / [-1+8]

= [-10 + 10] / 7

= 0 / 7

= 0

Therefore, the average rate of change of the function is: 0
