Answer:
A
Step-by-step explanation:
The points are similar
X=12.35
b = (2 × area)/a
= 5.63636
c = √ a2 + √ b2
= √112 + √ 5.63636363636362
= √152.76859504132
= 12.35996
Answer:
The average rate of change of change over the interval is 3.
Step-by-step explanation:
Given/Known:
( f(b) - f(a) ) / (b - a)
b = 8
a = -1
Solve:
( ((8)^2-4(8)-2) - ((-1)^2-4(-1)-2) ) / (8 - (-1))
(30 - 3)/(9)
27/9
3
The average rate of change is 3.
