A firefighter is on the fifth floor of an office building. She needs to throw a rope into the wiindow above her on the seventh floor. The function h=16t^2+36t models how high above her she is able to throw a rope. If she needs to throw the rope 40 ft above her to reach the seventhfloor window, will the rope get to the window?
I don't know where to plug each number in the equation.

I assume h = height = 40 feet. Whatever t stands for, I assume that is the value you are trying to find. Will it also be expressed in units of feet? If so, this leads me to:
16t^2 + 36t  40 = 0
4(4t^2 + 9t 10) = 0
Unfortunately, I am unable to factor it any further. Are there any typos in your formula?
Sorry that I can't be of more help. Thanks for asking.
