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.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

4x and 6y

im not sure though

chiken

step-by-step explanation:

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
