A small company is selling a new board game, and they need to know how many to produce in the future. After 12 months, they sold 4 thousand games; after 18 months, they sold 7 thousand games; and after 36 months they sold 15 thousand games.
1. Could this information be reasonably estimated using a single linear model?
-yes
-No

2. If so use the model to estimate the number of games sold after 48 months. If not explain your reasoning.

Two sides of a triangle mesure 20cm and 30cm. what is the measure of the third side

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:

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
