Answer:
The height of the pole is 105ft,
Step-by-step explanation:
Let us call the height of the pole, then we know that the distance from the bottom of the pole to the anchor point is 49, or it is
.
The wire length is 14 ft longer than height
, hence
.
Thus we get a right triangle with hypotenuse , perpendicular
, and base
; therefore, the Pythagorean theorem gives
which upon expanding we get:
further simplification gives
,
which is a quadratic equation with solutions
Since the first solution will give the triangle base length of
which is negative; therefore, we disregard it and pick the solution
.
Hence, the height of the pole is 105ft.
Answer:
Step-by-step explanation:
Use the formula
where P is the initial investment, r is the interest rate in decimal form, and t is the time in years. Filling in what we are given:
and simplifying a bit:
and a bit more:
A(t) = 5000(1.340095641) so
A(t) = 6700.48
