A basketball bounces off the ground. The ball's height y (in feet) after t seconds can be modeled by y=-16t^2 +20t. How many seconds is the ball in the air. The basketball teaches its maximum height after 0.625 second. What is the maximum height of the bounce.

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a> 1
