You need the compound interest formula solved for time:
Years = log (total / principal) / n * log (1 + rate / n)
Years = log (9,000 / 5,960.32) / 2 * log (1 + .042/2)
Years = log (
<span>
<span>
<span>
1.509986041</span></span></span>) / 2 * log (1.021)
Years = 0.1789729325 / 2 * 0.0090257420869
Years =

<span>
</span></span><span><span><span>0.1789729325 / 0.0180514842
</span>
</span>
</span>
<span><span><span>Years =
9.9145826746
</span>

Answer:
No
Step-by-step explanation:
The height, h of the tent attached below can be obtained using Pythagoras rule, as the shape forms a right angle triangle.
Length of base , = 24 / 2 = 12 feets
Hypotenus = 15 feets
The height, h = √(hypotenus² - Base²)
h = √15² - 12²
h = √225 -144
h = √81
h = 9 feet
Tent shouldn't be rented as it is below 10 feets

Answer:
$6 for a 1-minute call
Step-by-step explanation:
For duration "d" the costs of the plans are identical when ...
5 +1d = 1 +5d
4 = 4d . . . . . . . . add -1-1d to both sides
1 = d . . . . . . . . . divide by 4. Duration in minutes.
Then the cost for this 1-minute call is ...
5 + 1·1 = 6 . . . . dollars
Each plan will charge $6 for a 1-minute call.
