The average rate of change from x=8 to x=5 can be calculated as:

\frac{f(8)-f(5)}{8-5}

f(8) = 0
f(5) = 4

Using the values we get:

\frac{0-4}{8-5} \\  \\ 
 -\frac{4}{3}

So, first option gives the correct average rate of change from x=8 to x =5 for the given function.

Question 1:

We have a 45-45-90 right triangle with the hypotenuse being the length from one corner to the opposite corner.

Multiply 30 ft with the square root of 2 and use a calculator to help give you numerical value to get your answer.

30 \sqrt{2} \approx 42

Your answer is the second choice.

Question 2:

The equilateral triangle can be divided into 2 30-60-90 triangles with the longer leg being the altitude. To get half of the side length of the right triangle, divide the altitude by the square root of 3.

\dfrac{15}{ \sqrt{3} }=\dfrac{15 \sqrt{3} }{3}=5 \sqrt{3}

The full side length is double of that, which is 10 \sqrt {3}.

Multiply that by 3 to get the full perimeter.
10 \sqrt{3}*3=30 \sqrt{3}

Your answer is the third choice. Hope this helps! :)
