A golfer hits a ball from a starting elevation of 7 feet with a velocity of 70 feet per second down to a green

with an elevation of -2 feet. The number of seconds t it takes the ball to hit the green can be represented

by the equation - 16t2 + 70t +7=-2. How long does it take the ball to land on the green?

It takes the ball ___

seconds to land on the green.

Step-by-step explanation:

The second-grade equation must be rearragend into its standard form:

Roots can be found with the help of the General Equation for Second-Order Polynomial:

Only the first root offers a reasonable solution.

its d but looking at that hurts my eyes frfr

step-by-step explanation:

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
