Davis hit a baseball from a height of 3 feet above the ground at an angle of 24 degrees with the horizontal at an initial velocity of 110 feet per second. How far will the ball travel before it hits the ground?

8. Write a parametric equation for the flight of the ball.

9. Find the maximum height of the ball.

10. How many feet did the ball travel horizontally before it hit the ground?

Answer   (1) u.s.coast guard                (2)president major disaster declaration                (3) 72 hours;                 (4) u.s coast guard auxiliary;

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

How are we suppose to know this
