!!HURRY IM BEING TIMED 40PTS!!
Rudik [331]

The average rate of change in a function from a to b is

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


For the left function, from x = 4 to x = 5, the rate of change is


\frac{100-64}{5-4} = \frac{36}{1} = 36.


For the right function, the rate of change is


\frac{1024-256}{5-4} = \frac{768}{1} = 768


Using a ratio to compare the right function's growth rate with that of the left function, you get 768 \div 36 \approx 21.3.


The right function is growing approximately 21 times faster than the left function (over the interval from 4 to 5).

on the set of axes below, the vertices of triangle PQR have coordinates P (-6,7) Q (2,1) and R (-1,-3) what is the area of trian
VashaNatasha [74]

Answer:

Area of ΔPQR = 25 units

Step-by-step explanation:

We will use the following formula to calculate the area of triangle ΔPQR:

A = 1/2 | x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂) | = 1/2 |(-6(1+3) +2(-3-7) +(-1)((7-1)| =

A = 1/2 |-6 · 4 + 2 · (-10) + (-1) · 6| = 1/2 | -24-20-6| = 1/2 | -50| = 1/2 · 50 = 25

A = 25 units

God with you!!!
