the height of a 0.5-liter orange juice box with a square base is a function of the width of its base,



where w is the width of the base in centimeters. find the width of the juice box if its height is 20 centimeters.

w =

w=5 cm

Step-by-step explanation:

Functions

We know the height (h) of a box is a function of the width of its base:

We are required to find the width of the box when the height is h=20 cm

To find w in terms of h we must isolate w from the equation above

Operating

Taking the square root

Replacing the value of h=20

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
