Molly Invests $8,600 into her son's college fund, which earns 3% annual interest

8_murik_8 [283]

Answer:

n= 13.8 years

Step-by-step explanation:

First, we need to determine the daily interest rate:

Daily interest rate= 0.03 / 365

Daily interest rate= 0.000082

Now, using the following formula we can determine the number of days and years:

n= ln(FV/PV) / ln(1+i)

n= ln(13,000 / 8,600) / ln(1.000082)

n= 5,039 days

In years:

n= 5,039/365

n= 13.8 years

Find the missing side of the triangle. leave your answer in simplest radical form

KIM [24]

missing side is $x} = 10.15$ mi .

Step-by-step explanation:

Here we have the following info from the figure: A right angled triangle with following dimensions

$Perpendicular = x$

$base = \sqrt{122}$

$Hypotenuse = 15$

By Pythagoras Theorem :

$Hypotenuse^2 = Perpendicular^2 + base^2$

⇒ $Hypotenuse^2 = Perpendicular^2 + base^2$

⇒ $15^2 = x^2 + (\sqrt{122})^2$

⇒ $225 = x^2 + 122$

⇒ $x^2 = 225-122$

⇒ $x^2 = 103$

⇒ $(x^2)^\frac{1}{2} = (103)^\frac{1}{2}$

⇒ $x} = (103)^\frac{1}{2}$

⇒ $x} = 10.15$

Therefore, missing side is $x} = 10.15$ mi .
