So we can make this a triangle: the angle is 40° and the bottom side is 360. Therefore, we want to find the side opposite to the angle, where we use tangent, which is opposite (what we are trying to find)/ adjacent (which is 360 ft).

tan(40°)=x/360

x=360tan(40°) ≈ 302.07. Therefore, the answer is about 302 ft

Answer:

The value of account after 8 years is $8580

Step-by-step explanation:

Given in question as :

The principal that invested in an account = $6,000

The annual interest rate compounded quarterly = 4.5%

Time period = 8 years

Now from compound Interest method for quarterly .

Amount = Principal $( 1 + \frac{Rate}{4 \times 100})^{4 \times Time}$

Or,Amount = $6,000 $( 1 + \frac{4.5}{4 \times 100})^{4 \times 8}$

Or, Amount = $6,000 (1.430)

∴ Amount = $8580

Calculate the a) future value of the annuity due, and b) total interest earned. (From Example 2)

vredina [299]

Answer:

value: $66,184.15
interest: $6,184.15

Step-by-step explanation:

The future value can be computed using the formula for an annuity due. It can also be found using any of a variety of calculators, apps, or spreadsheets.

<h3>formula</h3>

The formula for the value of an annuity due with payment P, interest rate r, compounded n times per year for t years is ...

FV = P(1 +r/n)((1 +r/n)^(nt) -1)/(r/n)

FV = 5000(1 +0.06/4)((1 +0.06/4)^(4·3) -1)/(0.06/4) ≈ 66,184.148

FV ≈ 66,184.15

<h3>calculator</h3>

The attached calculator screenshot shows the same result. The calculator needs to have the begin/end flag set to "begin" for the annuity due calculation.

The future value of the annuity due is $66,184.15.

The total interest earned is the difference between the total of deposits and the future value:

$66,184.15 -(12)(5000) = 6,184.15

A total of $6,184.15 in interest was earned by the annuity.
