In 2010 an item cost $9.00. The price increase by 1.5% each
year.
Write an exponential growth function to represent this
situation:

Step-by-step explanation:

Let P be price after t year . From the formula of compounding

P = 9

Taking log to the base e on both sides

ln P = ln 9 + t ln 1.015

= (2.197 + .0149t )

P =

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
