An astronaut on the moon throws a baseball upward. The astronaut is 6‘6“ tall, and the initial velocity of the ball is 30 ft. per sec. The height s of the ball in feet is given by the equation S equals -2.7t squared+30t+6.5, where T is the number of seconds after the ball is thrown complete part A. A. After _ seconds the ball will be 14 feet above the moon surface.

answer: check all that apply, where the options?

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

the angles measure to 70 degrees, 70 degrees, 20 degrees, and 20 degrees
