Step-by-step explanation:
V = 1/3s^2h; where V is the volume, s is the side length of the square base, and h is the height.
s/h = 6/10 = 3/5
s = 3h/5
V = 1/3(3h/5)^2 h = 1/3(9h^2/25)h = 3h^3/25
dV/dt = 9h^2/25 dh/dt = 0.2 = 1/5
dh/dt = 5/(9h^2)
When h = 2
dh/dt = 5/(9(2)^2) = 5/(9 * 4) = 5/36 = 0.1389 inches per seconds.

Find the gradient of the line that is perpendicular to the line 2y=3+5x
Answer:
100 bicycles
Step-by-step explanation:
If C(x)= 0.2x²-0.4x+6.636
The general form of a quadratic expression is given as: ax²+bx+c
Therefore from C(x),
a=0.2, b=-0.4, c=6.636.
C(x) is a parabola with its "a" coefficient 0.2 being positive so the curve opens upward indicating that the vertex is a minimum.
We simply need to find the vertex of:
C(x)= 0.2x²-0.4x+6.636
This occurs when:
x = -b/(2a)
x = -(-0.4)/(2*0.2)
x = (0.4)/(0.4)
x = 1
Since x=1 at the vertex, the company should build 100 bicycles to minimize the average cost per bicycle.
