The volume of the given rectangular prism is: 729 m^3

Step-by-step explanation:

To find the volume of a rectangular prism, we will use the width, length and height.

From the given diagram:

Length = l = 9m

Width = w = 9m

Height = h = 9m

The formula for volume of rectangular prism is:

$V=l*w*h\\=9*9*9\\=729\ m^3$

The volume of the given rectangular prism is: 729 m^3

If f(x)=x^2−8x and g(x)=−12x^2 what is g(f(−4))?

Korolek [52]

Answer:

-27648

Step-by-step explanation:

In this problem, we are looking for the function of g in terms of the function f. Simply put, we just replace the variable x in the function g with f(-4).

Step 1, writing g(f(-4)):

$g(f(-4))=-12(f(x))^2$

Great! Let us substitute f(x) with the given expression.

Step 2, substituting and simplifying:

$\\g(f(-4))=-12(x^2-8x)^2\\g(f(-4))=-12((-4)^2-8*(-4))^2\\g(f(-4))=-12(16+32)^2\\g(f(-4))=-12*2304\\g(f(-4))=-27648$

g(f(-4) is $\fbox{-27648}$ .

I hope this helps! Let me know if you have any questions :)

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs

4vir4ik [10]

Since there are no negative values for x, the range starts when y=4 at x=0. This extends infinitely in the positive direction. Therefore, the range of the function is from 4 to positive infinity. In interval notation, that is [4,∞).

Write an equation of a line that passes through (5,

enyata [817]

Answer:

y = 1/5x - 11

Step-by-step explanation:

perpendicular to a line means we flip the slope to opposite of what it is

in other wrds, since your slope is -5, your new slope for the line perpendicular to it would be 1/5.

Now we just use the same equation to find the y-intercept, which is b.

y = mx + b; m is your slope and b is your y intercept.

use the points given; (5, -10).

-10 = 1/5(5) + b

-10 = 1 + b

-11 = b

now put your equation together since you have all the pieces

y = 1/5x - 11
