Answer:
Step-by-step explanation:
Subtract both sides from 35
Simplify:
Factor 
=0
Your answer will be z=57
and No solution
V=πr^2h/3=π·3^2·11.5/3≈108.38495 or 108.40 rounded
32 but make sure it’s emedicpend PAS
Total cost, C = 8x^2 + 12xz
volume, V = (x^2)*z = 10
C = 8x^2 + 12x*10/x^2
= 8x^2 + 120/x
dC/dx = 16x - 120/x^2 = 0
16x = 120/x^2
x^3 = 120/16
x = 1.957 ft
d^2C/dx^2 = 16 +240/x^3 = +ve for x = 1.957
so, C is minimum when
x = 1.957 ft z = 2.61 ft
Length of the base x is 1.957 ft and height of side z is 2.61 ft
The answer is 2:1 because at first your ratio would be 18:9 but if you divide that by 9 (for simplifying purposes) than its 2:1
