Answer:
time is 6.76 years
Step-by-step explanation:
given data
amount = $150
payment = $100
rate r = 6% = 0.06
to find out
time period t
solution
we know it is compounding continuous
so we will apply here formula that is
amount = payment ×
..........1
put here all value we get
amount = payment ×
150 = 100 ×
take ln both side
ln 1.5 =
0.40546 = 0.06t
t = 0.40546 / 0.06
t = 6.76
so time is 6.76 years
Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
