Does someone mind helping me with this? Thank you!

The given two polygons are similar to one another ~

Sides of the given polygons are in ratio of :

$\qquad \sf \dashrightarrow \: 28 : 4$

to put in simple Ratio ~

$\qquad \sf \dashrightarrow \: 7: 1$

So, the sides of the larger polygon are :

4 × 7 = 28

6 × 7 = 42

3 × 7 = 21

4 × 7 = 28

7 × 7 = 49

3 × 7 = 21

3 × 7 = 21

4 × 7 = 28

Now, to find the Perimeter of larger polygon ~ add the side length of all sides :

$\qquad \sf \dashrightarrow \:p = 28 + 42 + 21 + 28 + 49 + 21 + 21 + 28$

$\qquad \sf \dashrightarrow \:238 \: \: units$

F(x) = x^2-3<br> What is the average rate of change on the interval [-5, 2] ?

Mumz [18]

Answer:

$(-3)$ .

Step-by-step explanation:

Over this interval, the change in the value of this function is:

$f(-5) - f(2) = 22 - 1 = 21$ .

The corresponding change in the value of $x$ :

$(-5) - 2 = -7$ .

The average rate of change of function $f$ over this interval is equal to the change in the function value divided by the corresponding change in $x$ :

$\begin{aligned}& (\text{average rate of change}) \\ =\; & \frac{(\text{change in function value})}{(\text{change in $x$})} \\ =\; & \frac{f(-5) - f(2)}{(-5) - 2} \\ =\; & \frac{22 - 1}{-7} \\ =\; & \frac{21}{-7} \\ =\; & -3\end{aligned}$ .
