This is a compound interest problem, therefore s(t) should be in the form:
where:
t = time in years
s(t) = the value of your item after t years
a = the initial value of your item
r = rate
Therefore, we already know that a = 245$.
Now, we can calculate r:
![r = \sqrt[t]{ \frac{s}{a} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%5Bt%5D%7B%20%5Cfrac%7Bs%7D%7Ba%7D%20%7D%20)
![r = \sqrt[5]{ \frac{560.50}{245} }](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B5%5D%7B%20%5Cfrac%7B560.50%7D%7B245%7D%20%7D%20)
= 1.18
Therefore, the correct answers are a = 245 and r = 1.18
where:
t = time in years
s(t) = the value of your item after t years
a = the initial value of your item
r = rate
Therefore, we already know that a = 245$.
Now, we can calculate r:
= 1.18
Therefore, the correct answers are a = 245 and r = 1.18
Answer:
Miles flown in 23.19 hours = 166968 miles
Step-by-step explanation:
Given that:
A satellite flies 55584 miles in 7.72 hours
We will find the unit rate first,
Unit rate =
Unit rate = 7200 miles per hour
Miles flown in 23.19 hours,
Miles flown = 7200 * 23.19
Miles flown = 166968 miles
Hence,
Miles flown in 23.19 hours = 166968 miles
