Answer:
1987.2
Step-by-step explanation:
We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the strength of students increased by 8% to 2160 then the original was 92%.

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
92(2160)=100(y)
198720=100y
y=1987.2
There are 1987.2 as the original strength of students.

The formula for the volume of a cylinder is area of the base times the height.
To find the area of the base you must multiply pi times 5 squared (3.14*25=78.5)
Then you must multiply that times the height (78.5*3), which equals 235.5 cubic centimeters
Answer:
12
Step-by-step explanation:
h'(x) = [f(x)*g(x)] '=f'(x )g(x) + f(x)g'(x)
h'(1) = [f(1)*g(1)] '=f '(1)g(1) + f(1)g'(1)
From the table f '(1)= -3, g(1)=2, f(1)= 3, g'(1) =6
h'(1) = f '(1)g(1) + f(1)g'(1) = -3*2 + 3*6= - 6+ 18 = 12
