The volume of a cubic shaped water tank is 42875 m 3 , then the height of the water tank is ________m
Andrei [34K]

Answer:

The height of this cube-shaped water tank is 35 m.

Step-by-step explanation:

The formula for the volume of a cube of side length s is V = s^3.

Here V = s^3 = 42,875 m^3.

Taking the cube root of both sides, we obtain the side length, s:

s = ∛(42,875 m^3) = 35 m

The height of this cube-shaped water tank is 35 m.

Write an equation in standard form of the parabola that has the same shape as the graph of f(x)=5x^2or g(x)=-5x^2, but with a gi
pickupchik [31]
F(x)=5x^2 Has minimum (0,0)

g(x) = f(x) + 2 Shifts the graph two units up, then the minimum is 2+0=2.

h(x) = g(x+4) Shifts the graph four units left,  then the minimum is at 0-4 = -4.

Then h(x) = 5(x+4)^2 + 2 has the minimum (-4,2)

And p(x) = -5(x+4)^2 + 2 has the maximum (-4,2)
