Average rate of change of the function $=\frac{75}{2}$

Solution:

Given function: $f(x)=5(2)^{x}$ from x = 1 to x = 5

Substitute x = 1 and x = 5 in f(x).

$f(1)=5(2)^{1}=10$

$f(5)=5(2)^{5}=160$

Let us find the average rate of change of the function.

Average rate of change

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

Here a = 1 and b = 5.

$$=\frac{f(5)-f(1)}{5-1}$

Substitute f(5) and f(1).

$$=\frac{160-10}{4}$

$$=\frac{150}{4}$

$$=\frac{75}{2}$

Average rate of change of the function $=\frac{75}{2}$

Use the figure above for exercises 1 and 2 <br> 1) what does = ?<br> 2) m

A straight line is 180°. The angles of QRT (2x + 33) and TRS (5x - 21) make up the 180° angle. So you can do:

∠QRT + ∠TRS = 180°

(2x + 33) + (5x - 21) = 180°

2x + 33 + 5x - 21 = 180 Combine like terms

7x + 12 = 180 Subtract 12 on both sides

7x = 168 Divide 7 on both sides

x = 24

Now that you found x, you can find the angles of QRT and TRS.

m∠QRT = 2x + 33

= 2(24) + 33

= 48 + 33

∠QRT = 81°

m∠TRS = 5x - 21

= 5(24) - 21

= 120 - 21

∠TRS = 99°

Product of 32x25 and what is the strategy?

vichka [17]

32 x 25 = 800. One strategy you can use is by adding 32 25 times, or adding 25 32 times.
Hope this helps!
