Answer:
Step-by-step explanation:
<u>If I got it right, we have:</u>
- Formula Pf = P0*e^(rt)
- Pf = 75709
- P0 = 1349
- r = 25% = 0.25
- t = ?
<u>Substitute the given values and solve for t:</u>
- 75709 = 1349*e^(0.25t)
- e^(0.25t) = 75709/1349
- e^(0.25t) = 56.1223
- ln e^(0.25t) = ln 56.1223
- 0.25t = 4.03
- t = 4.03/0.25
- t = 16.12 hr

Answer:
c = 4
See explanation
Step-by-step explanation:
Given:
4c = 3c - 4
Your calculation:
4c = 3c + 4
4c = 4 - 3c
4c = 1c
c = 4/1
c= 4
Correct calculation:
4c = 3c + 4
Collect like terms by subtracting 3c from both sides
4c - 3c = 3c + 4 - 3c
c = 4
Check:
4c = 3c + 4
4(4) = 3(4) + 4
16 = 12 + 4
16 = 16
Therefore,
Your final answer is correct but your method of calculation is not correct
Answer:
<u>104 feet</u>
Step-by-step explanation:
- To get the height of the lighthouse, we need to take the sine function of the angle
- sin4° = 0.07
- sin4° = h/1480
- ⇒ h/1480 = 0.07
- ⇒ h = 1480 x 0.07
- ⇒ h = 103.6
- ⇒ h = <u>104 feet</u>
