Answer:
The answer is: πr² = 22/7×(2.1)² = 13.86 cm²
Answer:
7 x 10^7
Step-by-step explanation:
count the zeros
Part A
Y (x)=2700 (1+0.04)^x
Y (x)=2700 (1.04)^x
where x is the number of years
Part B
Y (12)=2,700×(1.04)^(12)=4,322.78
Round your answer to get 4323
Answer:
x = 6
Step-by-step explanation:
12 / 2
= 6
2 x 6
=12

Critical points is where the derivative (slope) is zero or does not exist. So to do this we have to find the derivative of our function:

So we apply chain rule:
=

Set our first derivative to zero and solve for x:
3(x^2 - 1) * 2x = 0
So we can see that (by plugging in) 0, -1 and 1 makes our solution true
So our critical value is x = 0, x = -1, x = 1
