At Willow Creek Farms, Chrissy likes to stack the mandarins in triangular pyramids. Each layer of mandarins is in the shape of an equilateral
triangle, and the top layer is a single mandarin.
1. How many mandarins are in a stack eight layers high?
2. How is this task similar to others we have done? How is it different? What types of patterns
are present in this situation?

Taking algebra two apex courses and need with these questions

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:
