Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5
f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559
g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72
h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337
<h2>587</h2>
Step-by-step explanation:
A lead cube of side
is used to make spherical pellets of diameter
.
As the volume of lead is conserved, the volume of raw material equals the volume of finished products.

Let us assume that
cubes are produced. Volume of a cube of side
is
. The volume of a sphere of diameter
is
.

n is rounded off to 587.
∴ 587 spherical pellets can be made.
30cm cubed the formula is v=bh
