<h3>Answer:  176.6</h3>

Work Shown:

b^2 = a^2 + c^2 - 2*a*c*\cos(B)\\\\b^2 = 150^2 + 30^2 - 2*150*30*\cos(150)\\\\b^2 \approx 31194.22863406\\\\b \approx \sqrt{31194.22863406}\\\\b \approx 176.618879608211\\\\b \approx 176.6\\\\

HELP PLEASE LOTS OF POINTS!!
Paladinen [302]

Answer:

<em>Thus, f and g are inverse functions</em>

Step-by-step explanation:

<u>Inverse Functions</u>

If two functions f(x) and g(x) are inverses, then it follows that:

f\circ g(x)=x

Or:

g\circ  f(x)=x

We are given

\displaystyle f(x)=\frac{1}{4}x-6

g(x)=4x+24

Let's test if they are inverse functions:

f\circ g(x)=\frac{1}{4}(4x+24)-6

Simplifying:

f\circ g(x)=x+6-6=x

Now find:

\displaystyle g\circ f(x)=4\left(\frac{1}{4}x-6\right)+24

Operating:

\displaystyle g\circ f(x)=x-24+24=x

Thus, f and g are inverse functions
