The height in meters of a baseball t seconds after it is hit straight up in the air with a velocity of 45 m/s is given by h=-9.8t + 45t + 1.2. How long is the ball in the air round your answers to the nearest tenth of a second

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
