16. Find the coordinates of point C if B(-3, 1) is the midpoint of segment AC 1 and point A has coordinates (1,7).

(-7, -5)

Step-by-step explanation:

Point A is at (1,7) and point B is at (-3,1). To get from the x-coordinate of A to the x-coordinate of B, you have to move right 4, or you have to subtract 4 from the x-coordinate of point A. To get to the x-coordinate of point C, you must do the same since B is the midpoint. -3 - 4 is -7. To get from the y-coordinate of A to the y-coordinate of B, you have to move down 6, or you have to subtract 6 from the y-coordinate of point A. 1 - 6 is -5.

The coordinates of point C are thus (-7,-5).

5%Step-by-step explanation:The amount is compounded annually for the first year, which means it compounds 10% every year. However, when the bank changes the policy, "semi annual compound" means it's going to compound every six months. Which is just half of the original, it's just divided by 2.

Sorry if I was wrong tho
