$100 is the principal deposited in a 5% saving account not compounded (simple interest). The same amount of $100 is placed in a 5% saving
account compounded annually. Find the total amount A after t years in
each saving plan and graph both of them in the same system of
rectangular axes. Use the graphs to approximate the time it takes each
saving plan to double the initial amount.

step-by-step explanation:

in which figure is point g a centroid

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
