Answer:
Average rate of change = 3
Step-by-step explanation:
- We know that the average rate of change is basically a measure of the slope of the secant line in the closed interval [a, b].
here a = -3 and b = 4
⇒ Average rate of change = f(b) - f(a) / b - a
= (27 - 6) / (4 - (-3))
= 21 / 7
= 3
Therefore, Average rate of change = 3
The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.
The perimeter is 16.2. Let me know if you need me to show you how I got this
