B) 185.78
C) 1300.48
D) 1310.72
For x = 10, f(x) = f(10) = 0.01(2)^10 = 10.24
For x = 17, f(x) = f(17) = 0.01(2)^17 = 1310.72
Now using formula for the calculation of average rate of change of f(x).
(f(b) – f(a)) / b – a = (f(17) – f(10)) / 17 – 10 = (1310.72 -10.24) / 7 = 185.78
So option “B” is correct.Answer:
the answer is b
Step-by-step explanation:

the use of the plane varies directly with the square root
of the time the plane is used. If a lesson plus 16 minutes
of plane usage costs $90, what is the total amount
charged for a lesson having 36 minutes of plane usage?
The total amount charged for a lesson having 36 minutes of plane usage is $110.
Given that, a flight instructor charges $50 per lesson, plus an additional fee for the use of his plane.
The charge for the use of the plane varies directly with the square root of the time the plane is used.
x∝√y
x=k√y
Here, 90 = 50 + k√16
k = (90-50)/4
k = 40/ 4
k = 10
For 36 minutes, total charge
Total amount charged = 50 +10√36
Total amount charged = 50 + 10×6
Total amount charged = 50+60
= $110
Therefore, the total amount charged for a lesson having 36 minutes of plane usage is $110.

Answer:
(-2, -2)
Step-by-step explanation:
Compare the two functions ...
f(x) = -|x +2| -2
f(x) = a·g(x -h) +k
where f(x) is a translation and scaling of function g(x). Here, you have ...
g(x) = |x|
The scale factor is a = -1.
The horizontal shift is h = -2.
The vertical shift is k = -2.
_____
The original vertex at (0, 0) has been shifted by (h, k) to ...
(0, 0) + (h, k) = (0, 0) + (-2, -2) = (-2, -2).
Answer:
(-2,-2)
