Maurinko [17]

The balance after one year is $5200

Step-by-step explanation:

The formula to apply here is

A=P(1+\frac{r}{n} )^{nt}

where

A=Amount of money  at the end of the period=?

P=the amount of money invested= $5000

r=rate of interest=4%=0.04

n=number of compounding per year=1

t=time in years=1

Applying  the formula

A=P(1+\frac{r}{n} )^{nt} \\\\\\A=5000(1+\frac{0.04}{1} )^{1} \\\\\\A=5000(1.04)\\\\A=5200

A=$5200

snow_tiger [21]

Answer:

Step-by-step explanation:

Using the area model and standard algorithm, we have:

                332   (tenths)

         <u> ×       21  </u>

                332

        <u>      664     </u>

        <u>      6972  </u> tenths = 697.2

<u />

              30      +      3      tenths

     1       300           32         332

    20     600           64         664

33.2 × 21 =<u>    30    </u> × <u>    1     </u>  =  <u>      30     </u>

ella [17]
The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.
 The searched polygon can be seen in the attached image.
 The area of the polygon will be the area of the square plus the area of the triangle.
 At = (6) * (8) + (1/2) * (5) * (8) = 68
 At = 68
 answer
 the area of the polygon is 68units ^ 2
