What is the volume of the regular pyramid?

ad-work [718]

Answer:

C

Step-by-step explanation:

The volume of the regular pyramid is $V=\dfrac{1}{3}A_{base}H.$

The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to

$A_{base}=6\cdot \dfrac{1}{2}\cdot 12\cdot 10.4=374.4\ cm^2.$

Hence, the volume of the pyramid is

$V=\dfrac{1}{3}\cdot 374.4\cdot 36=4,492.8\ cm^3.$

Given the function f(x) = -5x + 1 + 3, for what values of x is f(x) = -12?

irina1246 [14]

Answer:

$x=\frac{16}{5}$

Step-by-step explanation:

The given function is

$f(x) = -5x +1+3$

Which can be rewritten also as

$f(x) = -5x +4$

We want to find the values of x for which

$f(x) = -12$

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

$-12 = -5x + 4\\-16 = -5x\\x=\frac{-16}{-5}=\frac{16}{5}$
