0.20×63 +0.05×97 +0.35×85 +0.40×77 = 78
The student's overall final score is 78.
__
The letter grade earned is between 70 and 80, so is a C.
€ = 7/9
7/9÷2 = .389
C = 2pi•r = 2•pi•18 = 36pi
WV = 7/9 (36pi) = .389 (36)pi = 14pi
So C) 14pi is the answer

Step-by-step explanation:
The rate of change is found by
rate of change = f(b) -f(a)
------------
b-a
We need to find the rate of change for the interval 7,9 and 4,6
We know b= 9 and a = 7
f(9) -f(7)
------------
9-7
3878-1852

We know b= 6 and a = 4
f(6) -f(4)
