hypotenuse = $\sqrt{25+144}$

hypotenuse = $\sqrt{169}$

hypotenuse = 13

Perimeter = 5+12+13

Perimeter = 30

Average Rate of Change: $\displaystyle \displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

g(x) = 4x

Interval [1, 5]

Step 2: Find Change

Substitute in function and points [Average Rate of Change]: $\displaystyle \displaystyle \frac{4(5) - 4(1)}{5 - 1}$
[Fraction] Multiply: $\displaystyle \displaystyle \frac{20 - 4}{5 - 1}$
[Fraction] Subtract: $\displaystyle \displaystyle \frac{16}{4}$
[Fraction] Divide: $\displaystyle 4$
