1 answer:
We have two similar triangles, the one as a whole and the one inside of it. To calculate the height of the flagpole we can set up a proportion. First calculate the length of the base of the smaller triangle.
16.60 - 12.45 = 4.15m
The height is 1.65m, set up a proportion:
Cross multiply:
Divide 4.15 to both sides:
So the height of the flagpole is 6.6 meters tall.
16.60 - 12.45 = 4.15m
The height is 1.65m, set up a proportion:
Cross multiply:
Divide 4.15 to both sides:
So the height of the flagpole is 6.6 meters tall.

The amount of $7389.43 has to be invested at 5.9% interested continuously to have $15,000 after 12 years.
Step-by-step explanation:
The given is,
Future value, F = $15,000
Interest, i = 5.9%
( compounded continuously )
Period, t = 12 years
Step:1
Formula to calculate the present with compounded continuously,
...............(1)
Substitute the values in equation (1) to find the P value,
( ∵
)
( ∵
)
We change the P (Present value) into the left side,
≅ 7389.43
P = $ 7389.43
Result:
The amount of $7389.43 has to be invested at 5.9% interested continuously to have $15,000 after 12 years.
