Answer:
8%
Step-by-step explanation:
The amount repaid is ...
A = P(1 +rt)
Filling in the given values, we can find r.
(18·28) = 450(1 +r(18/12)) . . . . . t is in years
504 = 450 + 675t
54/675 = 0.08 = 8%
The simple interest rate on the loan is 8%.
The formula for angular frequency is:
ω = velocity/radius
Since we are given distance(8.0m) and time(11 seconds) , we can also express the formula as:
ω = distance/(radius)(time)
Substituting the given values:
8.0m/(0.241m)(11s)
Which would give us the answer of 3.03 seconds.
Hope this answer helps.
