The amount of money that John would have in his account when he is ready to retire is $6,351,400.21.

<h3>How much would be in the retirement account?</h3>

The formula that can be used to determine the future value of the annuity is

Future value = Daily deposit x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

  • r = 3.5 / 365 = 0.0096%
  • n = (65 - 48) x 365 = 6205

Annuity factor = [(1.000096^6205) - 1] / 0.000096 = $8468.53

Future value = 750 x $8468.53 = $6,351,400.21

Can someone help me find the area of this figure ? Thanks!
nordsb [41]

Answer:

  • 25 units²

Step-by-step explanation:

<u>We know that:</u>

  • Some squares are 100% shaded, and some are half shaded.
  • Half shaded squares: 10 squares
  • 100% shaded: 20 squares
  • Area of figure = Area of half shaded + Area of 100% shaded

<u>Solution:</u>

  • Area of figure = Area of half shaded + Area of 100% shaded
  • => Area of figure = (10 x 1/2) + 20
  • => Area of figure = 5 + 20
  • => Area of figure = 25 units²

Hence, the area of the figure is 25 units².

Use the quadrant system to find the area of the polygon.
adoni [48]

Consider the bottom most rectangle.

Its length = 5 - 2 = 3 units

Its width = 3 - 1 = 2 units

So, its area = 3(2) = 6 square units.

Consider the middle rectangle.

Its length = 2 - 1 = 1 unit

Its width = 4 - 2 = 2 units

So, its area = 1(2) = 2 square units.

Finally, consider the top rectangle.

Its length = 6 - 1 = 5 units

Its width = 6 - 4 = 2 units

Its area = 5(2) = 10 square units.

Hence, total area = 6 + 2 + 10 = 18 square units. Correct option is C.
