                                            etc.

marin [14]

Answer:

Step-by-step explanation:

I think this is the equation for annual compunt interest

FV = PV(1 + int)^time        PV is present value    FV is the future value

PV + Interest  =  FV

FV - PV = Interest

                           FV                   -      PV

Interest  = [3000(1 + 0.03)^30]   -   3000

              =    3000(1.03)^30    -   3000

              =    3000(2.4272)   -   3000

              =    7281.79   -   3000

              =    $4282     to the nearest dollar    <------------    Fianl Answer

Find the measure of an angle with measure between 0 and 360 that is conterminal with an angle measuring -800
igomit [66]
Add 720 degrees (which represents two full revolutions around the center) to -800.  Result:  -80 degrees.  This angle is in Quadrant IV.

Subtracting 80 from 360 will give you a positive angle co-terminal with -800 deg.  360 - 80 = ?

28/12 simplified (In simplest form.)
jekas [21]
You can start by turning it into a mixed number:
2 4/12
then you can simplify the 4/12 part by dividing by 2/2 and getting 2/6
then you can divide 2/6 by 2/2 and get ⅓
so 28/12 simplified is 2 1/3

Hope this helped!! :D
