I REALLY NEED HELP WORTH 10 POINTS URGENT!!!!!

Answer:

(f\circ g)(4)=31

Step-by-step explanation:

<u>Composite Function</u>

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

(f\circ g)(x)=f(g(x))

For practical purposes, it can be found by substituting g into f.

We have:

f(x)=3x+1

g(x)=x^2-6

Computing the composite function:

(f\circ g)(x)=f(g(x))=3(x^2-6)+1

Operating:

(f\circ g)(x)=3x^2-18+1

Operating:

(f\circ g)(x)=3x^2-17

Now evaluate for x=4

(f\circ g)(4)=3(4)^2-17=48-17

\boxed{(f\circ g)(4)=31}

The length of s is 2/3 the length of t. If s has an area of 368 cm squared find the perimeter of the figure
ser-zykov [4K]
s = \frac{2}{3}t&#10;\\\ \frac{2}{3}t*t = \frac{2}{3}t^2&#10;\\\ \frac{2}{3}t^2 = 368&#10;\\\ t^2 = \frac {3}{2}368&#10;\\\ t^2 = 552&#10;\\\ t \approx 23.5&#10;\\\ s \approx 15.6&#10;\\\ P \approx 78.2
