7) A water balloon is launched into the air. It travels 20 meters horizontally and reaches a maximum height of 30 meters. Write the exact equation of the quadratic function that models the path of the water balloon. Use the form y = a(x - h)² + k a (x-10)² +30 (10,30) = Y 0 = 0 = 1000 + 30 a (20-10)² + 30

Q: 43=31-5(1-5w)

A: Given that,   43 = 31 - 5(1-5w) We have to solve for w.

Q: Simplify -9/4(1/2)+3/4 / 5/6

A: Here we use the result that (a/b)*(c/d)=ac/bd and (a/b)/(c/d)=ad/bc , and we simplify the two…
