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.

HELPPP IF YOU CAN DO THISSSS (BRAINLIST) thank youuu
grigory [225]

Answer:

a) $50,880

b) $48

c) 1060

Step-by-step explanation:

a)

-320x^2 + 1920x + 48000 = 0

This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)

x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3

The maximum revenue, y, is the value of the function evaluated at x = 3.

f(x) = -320x^2 + 1920x + 48000

f(-3) = -320(3)^2 + 1920(3) + 48000

f(-3) = 50,880

The maximum revenue is $50,880

b)

Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48

c)

$50,880/$48 = 1060
