Answer: 70 square centimeters.

Explanation: The area of a parallelogram is base times height.

Because the parallelograms are congruent, we can do 4*(3.5*5), which equals 70 square centimeters.

The linear function f(x) = 0.2x + 79 represents the average test score in your math class, where x is the number of the test tak
mario62 [17]

Using linear function:

A. f(2) = 79.4

B. g(2) = 84

C. Science class had the higher average after test 4.

<h3>How to Find the Equation of a Linear Function?</h3>

We are given the linear function for test score for Math class as, f(x) = 0.2x + 79.

Find the slope (m) and y-intercept (b) for function g(x) for science class.

Using (1, 86) and (2, 84):

Slope (m) = change in y/change in x = (86 - 84)/(1 - 2) = -2

Substitute m = -2 and (x, y) = (1, 86) into y = mx + b to find b:

86 = -2(1) + b

86 + 2 = b

88 = b

b = 88

Substitute m = -2 and b = 88 into g(x) = mx + b:

g(x) = -2x + 88

Part A: Substitute x = 2 into f(x) = 0.2x + 79

f(2) = 0.2(2) + 79 = 79.4

Part B: Substitute x = 2 into g(x) = -2x + 88

g(2) = -2(2) + 88 = 84

Part C: Substitute x = 4 into f(x) = 0.2x + 79 and g(x) = -2x + 88 respectively

f(4) = 0.2(4) + 79 = 79.8

g(4) = -2(4) + 88 = 80

Science class had the higher average after test 4.

In the summer a large pool evaporates water at 15% per day. If the pool starts out with 25,700 gallons of water, which function
JulijaS [17]

Answer:

y=25,700(0.85)^{x}

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

y=a(b)^{x}

where

y ----> represent the pool’s loss of water

x ----> the number of days

a is the initial value

a=25,700 gal

b ----> is the base

r=15%=15/100=0.15

b=(1-r)=1-0.15=0.85

The function is equal to

y=25,700(0.85)^{x}
