Answer:

Step-by-step explanation:

The rate of change of a function f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

here [ a, b ] = [ 3, 7 ]

f(b) = f(7) = 47 and f(a) = f(3) = 11, hence

rate of change = $\frac{47-11}{7-3}$ = $\frac{36}{4}$ = 9

A flying squirrel's nest is 12 feet high in a tree. From its nest, the flying squirrel glides 13 feet to reach an acorn

Answer: the answer should be 5

if you draw a right triangle 12 would be the line that goes up (A) and 13 would be the slanted line (C) so that leaves the bottom line to be C.

hope this helps!

Step-by-step explanation:

$A^{2} +B^{2} =C^{2} \\12^{2} +B^{2} =13^{2} \\144+B^{2} =169\\-144 -144\\\sqrt{B^{2} } =\sqrt{25} \\ B=5$
