A Daredevil Jumps Off A Tall Building. He Falls Freely For Several Seconds Before Releasing His Parachute . His Height (h) In Meters , T Seconds After Jumping Can Be Modeled By : h=4.9t^2+t+360 before he releases his parachute and h=4t+142 After He Releases His Parachute . How Long After Jumping Did He Release His Parachute ? HELPP ME PLEASE !!!!

Best ResponseYou've already chosen the best response.0The height functions will be equal when he releases the parachute \[4.9t^2+t+360=4t+142\] Make one side equal to 0 and use the quadratic equation to solve

Best ResponseYou've already chosen the best response.0It should be 4t + 142 on the right side. the next step is to make one side be 0 by adding or subtracting everything on that side of the equation. You have 4t on the right side. How would you move it from the right to the left?

Best ResponseYou've already chosen the best response.0So Where It Says Add Or Subtract ?

Best ResponseYou've already chosen the best response.0You want to add the 4t because it's actually 4t (at least it is in the original problem statement). Whatever the sign is, do the opposite

Best ResponseYou've already chosen the best response.0yeah, what did you get as the equation though? I left the addition/subtraction for you to do

Best ResponseYou've already chosen the best response.0I aligned the terms so you can actually add straight down. What's\[t+4t=\] and \[360142=\]

Best ResponseYou've already chosen the best response.0t + 4t = 5t (add the coefficients, never change the exponents when adding or subtracting). So this is the equation dw:1439937754826:dw
