12.726 is the correct answer if I am correct, because you round the number if it is five or more! Hope I helped
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
Answer:
if you meant y^8*y^2 then y^10 if you meant 8y*2y then 16y^2
Answer:
-1/6
Step-by-step explanation:
find a common denominator. the easiest way to do that is multiply them together. 3x2 is 6
so what do you multiply 2 by to get to 6? 3.
so you multiply 1/2 by 3/3 (which is a fancy 1) to get 3/6
same for the other side multiply by 2/2 to get 4/6
3/6- 4/6 = -1/6
