Davis notices that his hair is decreasingly exponentially at a rate of 10% per year. if he starts with 100,000 on his head, how many will he have after 3 years?

It would be 72,900 hair loss after 3 years.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
