Hello, i am doing a quadratic problem and am very stuck. English is my not first language so maybe i dont understand the question fully. Any help would be appreciated
The question is as follows:
A model rocket is launched from a field. The height of the rocket, y, in feet above the
ground, after x seconds is modelled by the equation y = -16x^2+ 177x + 4. From the 10th
floor of a nearby building, a boy looks out a window when he hears the rocket fired. The
boy's line of sight is given by the equation y = 65x+ 100.
A) Graph the path of the rocket and the boy's line of sight: on the same set of axes.
B) How high will the rocket be when the boys line of sight sees the rocket and how long after
launch will the boy see the rocket?
(i show the graph provided)
