Given f of x is equal to the quantity x plus 3 end quantity over the quantity x squared minus x minus 12 end quantity and g(x) =

Westkost [7]

From the given f(x) and g(x), the value of (g-f)(2)=1

Given :

The functions are

$f(x)=\frac{x+3}{x^2-x-12} \\g(x)=log_4(x)$

Lets evaluate (g-f)(2)

$(g-f)(2)=g(2)-f(2)$

To find out g(2), replace 2 for x in g(x) and then replace 2 for x in f(x)

$f(x)=\frac{x+3}{x^2-x-12} \\g(x)=log_4(x)\\x=2\\f(2)=\frac{2+3}{2^2-2-12}=\frac{5}{-10}=-\frac{1}{2} \\\\g(2)=log_4(2)=\frac{1}{2}$

Now we find g(2)-f(2)

$(g-f)(2)=g(2)-f(2)=\frac{1}{2}-\frac{-1}{2} =1$

Now evaluate. Substitute −2 for x in the composition f(g(x)) = 4x6 + 4x3 + 1, then simplify. f(g(−2)) =

Viktor [21]

F(g(-2))=4(-2)^6+4(-2)^3+1
f(g(-2))=4(64)+4(-8)+1
f(g(-2))=256-32+1
f(g(-2))=224+1
f(g(-2))=225

A carpenter needs to cut four sections, each 3–feet 8–inches long, from a piece of molding. If the board is only sold by the foo

KIM [24]

Alright, lets get started.

The length of each section what carpenter needs to cut is 3 feet and 8 inches.

Converting 3 feet and 8 inches into feet only, we know, $12 inches = 1 feet$

So, 3 feet 8 inches = $3 +\frac{8}{12} =3 +\frac{2}{3} =\frac{11}{3}$ feet

It means length of each section = $\frac{11}{3}$ feet

Carpenter needs to cut 4 sections, so length of 4 sections will be = $4*\frac{11}{3}=\frac{44}{3}=14\frac{2}{3} feet$

2/3 feet means 8 inches so she needs board 14 feet 8 inches

Board is only sold by the feet only so, she has to puchase 15 feet board. : Answer

Hope it will help :)

Please answer ASAP! I will give Brainliest! A picture of the options are shown if the words don't make sense to you. <3

Sedbober [7]

I'm assuming that by "variable" it more means "non-linear".

<h3>In this case, the correct option would be B.</h3>

Graphs A, C, and D are all linear, straight lines. B, however, is a curved line, which means there is an exponent involved.
