We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.
Answer:
It should be A
Step-by-step explanation:
This is because when we insert 3 into x we would get:
y = -2
By looking at the pics only one looks setting to the formula
Answer:
approx. 905 in³
Step-by-step explanation:
The height is half its radius, and therefore the height is (1/2)(12 in), where 12 in represents half the diameter (24 in).
The formula for the volume of a cylinder of radius r and height h is
V = (1/3)(πr²)(h). Using the values r = 12 in, h = (1/2)(12 in), we get:
V= (1/3)π(12 in)²(6 in), or
V = (1/3)(144 in²)(6 in), or
V = 288π in³, or approx. 905 in³
Answer:
5
Step-by-step explanation:
(y2-y1)/(x2-x1), when you plug the numbers into the formula, you should get 5
