Answer:
Step-by-step explanation:
Substitute x = 2 into both h(x) and f(x)
h(2) = = 1 ⇒ (h(2))² = 1
f(2) = 2 + 2 = 4
Hence
when x = 2
=
Well, it can be easily done by differentiating function of area with respect to one of either height or radii/diameter (if calculus is enabled).say:A=pi*r^2 + 2pi*r*hV=pi*r^2*h or h=V/(pi*r^2)thenA=pi*r^2 + 2pi*r*V/(pi*r^2)to minimize surface area, we make dA/dr = 0try to do the rest, you'll find 2r = h
Answer:
Edge length of the cube = 27 m
Dimensions of the box is length = 135 m, width = 81 m, height = 27 m
Step-by-step explanation:
The box contains 15 identical cubes therefore, we have
Edge length of cube = Side, s, of cube
15 × s³ = 295245 m³
∴ s³ = 295245/15 = 19683 m³
s = ∛19683 = 27 m
Hence the edge length of the cube = 27 m
The dimension of the box is length = 5 × 27 = 135 m
Width = 3 × 27 = 81 m
height = 27 m.
