4. An investment account pays 4.6%
1 answer:
Answer:
Step-by-step explanation:
Use the formula
where A(t) is the amount after all the compounding is done, P is the initial investment, r is the interest rate as a decimal, n is the number of times the investment is compounded each year, and t is time in years. For us,
P = 6050
r = .046
n = 4
t = 6
A(t) = ?
Filling in our given info:
which simplifies to
which simplifies a bit more to
and
A(t) = 6050(1.31577397) so
A(t) = $7960.43
which is choice C

Since s and t are complimentary, that means ∠s + ∠t = 90
From the picture, we also know that ∠t + ∠LGM = 90
Set them equal to each other:
∠s + ∠t = ∠t + ∠LGM, solve:
∠s = ∠LGM
Now using the fact that tangent = opposite/adjacent:
tan (∠s) =
tan (∠s) =
Set them equal to each other to get:
=
Solve:
Part B:
Using tan (∠s) =
We get: meters
