Answer:265.25
Step-by-step explanation:
Given
Volume of box
height is 3 times the width
let height, length and breadth be H, L & B
4=B^2\times L[/tex]
Cost of side walls $ 
Cost of base $ 
Cost of side walls
Cost of base 
Total cost 
differentiate C w.r.t B to get minimum cost
L=2.19 m
C=$ 265.25
Problem 3
This is not an exponential function. If you were to graph this out, you would see a parabola forming. Or at the very least, a parabolic-like curve forms. An exponential curve only increases or only decreases for the entire domain. However, in this case, we have an increasing portion, and then it decreases.

Problem 4
This is an exponential function. Each time x increases by 1, y is multiplied by 4. The equation that models these points is y = 4^x. Note how the function is strictly increasing and there are no decreasing portions mixed in.
Radius is half of diameter so the diameter would be so 1.5 and 6. And circumference is 2(pi)(radius). So that's around 9.4 for the first question and 38 for the second
Answer:
90%
Step-by-step explanation:
18 divided by 20 = .9 witch means 90% of 1
