Aball is thrown from a height of 160 feet with an initial downward velocity of 12/fts. the ball's height h (in feet) after t seconds is given by the following: h = 160 − 12t - 16t^2 how long after the ball is thrown does it hit the ground?

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
