Step-by-step explanation:

d = 2r => r = d/2 = 16in/2 = 8 inches

V = Ab×h

= π·r²×h

= 3.14·(8in)²×5in

= 1004

If f'(x) is (x-4)(4-2x) , what is f(x)?
butalik [34]
We can apply some rules backwards

first
f'(x)=
(x-4)(-2x+4)
-2x^2+12x-16

we know that
f'(rx^n)=rnx^{n-1}
so therefor maybe
-2x^2=rnx^{n-1}
2=n-1
n=3
rn=-2
3r=-2
r=-2/3

one is
\frac{-2}{3}x^3
second part

12x
12x=rnx^{n-1}
x^1, 1=n-1
n=2
rn=12
2r=12
r=6
6x^2 is the second bit

last part
-16
-16x^0=rnx^{n-1}
0=n-1
n=1

rn=-16
1r=-16
r=-16

-16x^1

so therfor f(x)=\frac{-2}{3}x^3+6x^2-16x

Suppose a study of population 400,000 has been growing at rate of 7% per year if this rate continues find the population of this
inessss [21]

Answer:

680,000

Step-by-step explanation:

Population before growing rate: 400,000

Growing rate: 7%

Duration: 10 years

___

First, you will have to calculate how much does the population increase each year with the said rate, so you will have to multiply the rate by the population to determine that amount.

400,000 x 7/100 = 28,000

So the population increases by 28,000 each year, now you will have to multiply that amount by the amount of years to determine how much the amount of increase.

28,000 x 10 = 280,000

This means that the population has increased by 280,000 in these 10 years. Finally, you will have to add that number to the population amount to get the answer.

400,000 + 280,000 = 680,000
