Express the edge length of a cube as a function of the cube's diagonal length d. Then express the area and volume of the cube as a function of the diagonal length.

Step-by-step explanation:

d² = x² + x² + x²

d² = 3x²

d²/3 = x²

x = √(d²/3)

x = d√(1/3)

x = (d/3)√3

A = 6x²

A = 6((d/3)√3)²

A = 6(((d²/9)3)

A = 2d²

V = x³

V = ((d/3)√3)³

V = ((d³/27)3√3)

V  = (d³/9)√3

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
