PLEASE I NEED AN ANSWER NOW
You invest $200 when you turn 18 years old. You are told
your money will double every 4 years. How much money
will you have when you are 42 years old?

(and maybe if you can answer this part, thank you)
If it doubles every 6 years instead of every 4, how would your
investment worth change?
(again, this part is optional)

$12,800

Step-by-step explanation:

42-18= 24

24 is the years the money is growing.

24/4=6

200x2x2x2x2x2x2=12,800

if it doubles every six years it would be 200x2x2x2x2=3,200

the difference is 9,600

At 42 years old you would have $2278.13.

If it doubles every six years,  then you would have $1012.50.

Step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
