1- An object has been thrown straight up into the air. The formula

h = vt 16t²

gives the height h of the object above the ground after t seconds, when it is thrown upward with an initial velocity v. After how many seconds will the object hit the ground if it is thrown with a velocity of 128 feet per second?

2-The height h in feet reached by a dolphin t seconds after breaking the surface of the water is given by

h = 16t² + 32t.

How long will it take the dolphin to jump out of the water and touch the trainer's hand when h = 16?

3-Men are diving from a cliff to the water 16 feet below. A diver's height h (in feet) above the water t seconds after diving is given by

h = 16t² + 16.

How long does a dive last?

4-A table is rectangular and its length is twice its width. Find the dimensions of the table if it occupies 32 ft² of floor space.

5-The area of a rectangle is 40 square inches. Its length x is 3 inches more than its width. Find the length x in inches of the rectangle. (Enter an exact number.)
