Answer:

y-intercept is the weight of the animal at birth (when x = 0)

Step-by-step explanation:

y=3.86x+15

The slope (gradient) of the function is 3.86

The y-intercept of the function is 15

Therefore, the y-intercept is the weight of the animal at birth (when x = 0)

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:

<u>First, we need to determine the daily interest rate:</u>

Daily interest rate= 0.03 / 365

Daily interest rate= 0.000082

<u>Now, using the following formula we can determine the number of days and years:</u>

n= ln(FV/PV) / ln(1+i)  

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

n= 5,039 days

<u>In years:</u>

n= 5,039/365

n= 13.8 years
