B)Yes, one pair of opposite sides could measure
10 in., and the other pair
could measure 8 in

C)No, there are three different values for x when each
expression is set equal to 10.

D)No, the value of x that makes one pair of sides
congruent does not make the other pair of sides

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
