Answer:
The rate of interest is 9.5092%
Step-by-step explanation:
Given as :
The investment amount = p = $857
The Amount after 6 years = A = $1268.36
The time period = t = 6 years
Let The rate of interest = r%
<u>Now, From Compound Interest method </u>
Amount = Principle × 
Or, A = p × 
Or, $1268.36 = $857 × 
Or,
= 
Or, 1.48 = 
Taking power
both side
So,
= 
Or, 10.5092 = 1 + 
Or, 10.5092 - 1 = 
Or, 9.5092 = 
∴ r % = 9.5092
So , The rate of interest = r = 9.5092 %
Hence, The rate of interest is 9.5092% Answer
Answer:
98,100
Step-by-step explanation:
The distance the tip travels is
2π·(40 m) = 80π m
Then its speed is
(80π m)/(10 s) = 8π m/2 ≈ 25.1 m/s
