While hovering near the top of Ribbon Falls in Yosemite National Park at 1600 ft, a helicopter pilot accidentally drops his sunglasses. The height h(t) of the sunglasses after t seconds is given by the polynomial function h(t)= -16t^2+1600. When will the sunglasses hit the ground?
MY QUESTION IS- Why can't I use properties of equality to solve this equation? Is it because its a quadratic equation and you can only use the prop of equality on linear equations?
Actually, you CAN use your method. The only step that is dangerous that you took is this one:
t^2 = 100 -----> t = +/- 10
Remember that whenever you take the square root of both sides, you have to use +/-. There IS no one correct way to solve it - your way is just as good as the book's way, if you do it correctly.
