: A model rocket is launched from the ground with an initial velocity of 62 feet per second. The formula for the height H of a projectile after time t is given by H=−1/2gt^2+vt+h, where g is the acceleration due to gravity, which on Earth is 32 feet per second squared in U. S. Customary units, v is the initial velocity, and h is the object's starting height above ground. How long does it take until the rocket returns to the ground? Enter the answer rounded to the nearest tenth of a second.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
