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.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

answer: i can’t tell you that

step-by-step explanation:

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
