Step-by-step explanation:

a) The volume of the prism is

V = (n^2 - 1)×(n^2 - 1)×(5n)

\:\:\:\:= (n^4 - 2n^2 + 1)(5n)

\:\:\:\:=5n^5 - 10n^3 + 5n

b) If the dimensions L of the prism are tripled, the new volume will be

V' = (3L)^3 = 27L^3 = 27V

so it will increase by a factor of 27.

castortr0y [4]

Answer:

The answer is option 2.

Step-by-step explanation:

In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.

For example,

d = 0.5 + 5t

Let t = 1,

d = 0.5 + 5(1)

d = 5.5 \: miles

Let t = 5,

d = 0.5 + 5(5)

d = 25.5 \: miles

Therfore, as time increases, distance will also increase.
