Trevor deposited $8,000 into a savings account that earns 4% compound interest. How much interest did he earn after three years?

$8998.91

Step-by-step explanation:

8000*1.04^3

it is to the power of 3 because this is the number of years

it is multiplied by 1.04 because there is 4% interest and it is 1.something because you want to add tp the 8000 so you have to multiply it by more than 1

it is 04 because this is where the units go (if it was 40% then the multiplier would be 1.4

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.
