Answer:

8 years

Step-by-step explanation:

100e^(.05t) = 150 . . . . . a better model of the situation

e^(.05t) = 150/100 . . . . divide by 100

0.05t = ln(1.5) . . . . . . . . take natural logs

t = ln(1.5)/0.05 ≈ 8.11 . . . . divide by the coefficient of t

The money has been invested for about 8 years.

Can u guys please help me!!

Alona [7]

Answer and Step-by-step explanation:

This problem requires the use of trigonometric functions, specifically the tangent trig function.

$tan(Angle)=\frac{opposite}{adjacent}$

Plug in the values.

$tan(40) = \frac{8000}{x}$

Multiply by x to both sides, then divide by tan(40) to both sides.

$x = \frac{8000}{tan(40)}$

Now, plug this into a calculator and rounded to the nearest whole number (foot).

x = 9534.0287

x = 9534 ft.

The answer is 9534 ft., the last option.
