Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
Answer:
3602
Step-by-step explanation:
Formula = Population after n years = 2000( 1.04)^n
15 years the population will be 2000(1.04)^15
=3602.
The ratio of length to width would change slightly, before adding on to the dimensions, the ratio is 6 : 2.5 with the added dimensions, the ratio would change to 8 : 4.5 with simple math you can see that 2.5 is less then half of 6 while 4.5 is more then half of 8
