Answer:

- 3

Step-by-step explanation:

Differentiate f(x) using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given f(x) = $\frac{3}{x}$ = 3 $x^{-1}$ , then

f'(x) = - 3 $x^{-2}$ = - $\frac{3}{x^2}$

f'(1) = - $\frac{3}{1}$ = - 3

Because the triangles are similar the ratio of all the sides would be the same. So you need to find the ratio of the common sides and then use that ratio to find the unkown side.

In this picture sides FG = 52, FV would be the same side and is 24.

Dividing 24/52 = 0.461, so the unkown side WV would be 0.444 of it's common side HG.

HG = 39

39 * 0.461= 18.

The answer is C. 18

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.
