Time taken to reach a person located 5m from the source is 0.2s
<u>Explanation:</u>
Given:
Frequency, f = 10Hz
Wavelength, λ = 2.5m
Distance, d = 5m
Time, t = ?
We know:
velocity = f X λ
v = 10 X 2.5
v = 25 m/s
We know:
Distance = speed X time
On substituting the value we get:
5 = 25 X t
t = 0.2 seconds
Therefore, time taken to reach a person located 5m from the source is 0.2s

Step-by-step explanation:
Answer:
The answer is (B) $1,307
Step-by-step explanation:
First you would plug the $5000, 5 Years and 8% Interest(Compound) into your Formula - A=P(1+r)t
A=5000(1+.08)5
Which the interest is $2346.64
<u>__ _________________________________________________</u>
Next you would plug $5000, 3 Years and 6.5% Interest(Compound) Into your Formula - A=P(1=r)t
A=5000(1+.065)3
Which the future value is $1039.75
<u>__ _________________________________________________</u>
Finally you would subtract $2346.64 by $1039.75 and then round the difference to the nearest dollar.
