The formula of a volume of a rectangle prism:

l - length
w - width
h - height
We have

Substitute:

<h3>Answer: V = (10n³ + 50n² + 20n + 100) in³</h3>
A. 8.53 units is the length of the straight which is perpendicular to the straight line CD
Answer:
t=1/30 h = 2 min
Step-by-step explanation:
d = vt
system of equations:
d = 13t
d - 2/5 = t -> d = t+2/5
Solve
13t = t +2/5
t = 1/30 h = 60 min / 30 = 2 min
we have
which is a cubic function.
and
.
from f(x) and g(x) we know that both are cubic and g(x) has shrink of 1 and up by 4 units in x axis .
