4 x 22 =?
the question mark is how old they'll be.
Answer:
D. 405
Step-by-step explanation:
First, you find the area of the swimming pool without the water. That is 9 x 9 = 81. Then you multiply the area (without water) by 5 to find the area with the water.
Sequence: -4, 8, -16
rate of increase: -16/8 = -2
If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n.
The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms.
An = -4(-2)^(n-1)
Solving for the 5th term A5, use n = 5
A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64
So the answer is B.
