Answer:
p(0) = 800
p(8) = 997
Step-by-step explanation:
p(t) = 800 * (1.028)^t
The current price is when t=0
p(0) = 800 * (1.028)^0
= 800(1)
= 800
The price in 8 years
p(8) = 800 * (1.028)^8
=997.7802522414861936754688
To the nearest dollar
= 998
Answer:
Step-by-step explanation:
I'm goig to assume that the formula we need here is the following:
![A(t)=P(1+\frac{r}{n})^{(n)(t)](https://tex.z-dn.net/?f=A%28t%29%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7B%28n%29%28t%29)
where A(t) is the amount in the account after the compounding is done, n is the number of times per year the compounding occurs, r is the rate in decimal form, and t is the time in years. Filling in accordingly,
and simplifying a bit,
and simplifying a bit more,
A(t) = 90000(1.343916379) so
the amount in the account after 5 years is
A(t) = 120,952.47
Divide 7 by 8 then multiply what you get by 100.
Answer:
A
Step-by-step explanation:
=16x²-25
=(4x)²-(5)²
Using formula a²-b²=(a+b)(a-b)
=(4x+5)(4x-5)
A is increasing , b is maximum , c is decreasing, and d is minimum
