Liono4ka [1.6K]

The first step for this problem should always be to draw out the triangle so that you can right down the angles and side lengths. Afterward, you can use SOHCAHTOA to find the height of the tree. You would use tangent. The equation you would use is tan(28°)x/18. After solving for x, you will find the answer which is approximately 9.57 feet.

Hope this helped :)

1. Two thousand dollars is invested at 5.5 percent interest compounded

Dafna11 [192]

Two thousand dollars is invested at 5.5 percent interest compounded

quarterly for 2 years. Then the amount is $ 2230.88

<u>Solution:</u>

Given that Two thousand dollars is invested at 5.5 percent interest compounded quarterly for 2 years

<em><u>The formula for amount using compounded quarterly is given as</u></em>:

$\text { Amount }=P\left(1+\frac{R / 4}{100}\right)^{4 T}$

Where, "p" is the principal sum

"R" is the rate of interest

"T" is the number of years

Here in this problem,

P = 2000 ; R = 5.5 ; T = 2 years

Plugging in values in formula we get,

$\text {Amount}=2000\left(1+\frac{\frac{5.5}{4}}{100}\right)^{4 \times 2}$

$=2000\left(1+\frac{1.375}{100}\right)^{8}$

On solving we get,

$=2000(1+0.01375)^{8}=2000(1.11544)=2230.88$

Hence the amount is $ 2230.88
