Aright triangle's height is 3 times the length of its base. if the area of the triangle is 600, what is the height?

An architect is designing a water fountain for a park she uses the given function to model the water jet flowing from the fountain nozzles where h(x) gives the height of the water jugs in feet x feet from the starting point h(x)=-1/20x+x+15

The parabola x = y² - 9 opens: a.)up b.)down c.) right d.)left
