Step-by-step explanation:

f(g(10))

This is called a composite function. It's when you plug one function into another.

First, find g(10):

g(x) = √(x-9)

g(10) = √(10-9)

g(10) = √1

g(10) = 1

Then plug that into f(x):

f(x) = -9x - 9

f(g(10)) = -9 g(10) - 9

f(g(10)) = -9 (1) - 9

f(g(10)) = -9 - 9

f(g(10)) = -18

The base area of a triangular pyramid is 22 square yards and the height of the pyramid is 15 yards. What is the volume of the tr

Vaselesa [24]

Answer:

110 yd cubed

Step-by-step explanation:

The volume of a triangular pyramid is denoted by: $V=\frac{1}{3} Bh$ , where B is the base area and h is the height. We already know here that B = 22 and h = 15, so we can just plug in these values:

$V=\frac{1}{3} *22*15=110$

Thus, the volume is 110 yards cubed.

Hope this helps!
