Write and expression you can use to find the value of the cube then find the value if y=9 feet

V = s^3

V = 729 ft^3 when the side length is 9 ft

Step-by-step explanation:

The volume of a cube is given by

V = s^3  where s is the length of a side

Assuming you mean the side length is 9 ft

V = 9^3

V = 9*9*9

V =729 ft^3

A. 79.4B. 84C. Science class

Step-by-step explanation:

Average test score in math class

f(x) = 0.2x + 79

Average test score in science class

As per table the rate of change is -2, therefore g(x) is

g(x) = -2x + 88, becauseg(1) = -2 + 88 = 86

Part A: Determine the test average for your math class after completing test 2.

f(2) = 0.2*2 + 79 = 0.4 + 79 = 79.4

Part B: Determine the test average for your science class after completing test 2

g(2) = 84 given in the table

Part C: Which class had a higher average after completing test 4?  

f(4) = 0.2*4 + 79 = 0.8+ 79 = 79.8g(4) = -2*4 + 88 = - 8 + 88 = 80

Science class had higher class
