What will be the coordinates of N after a 90 degree counterclockwise around the origin

Prove that 3: 8 is equivalent to 12: 32.a. use diagrams to support your answer.

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

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0
