You and a friend decide to go skydiving. Your friend jumps from the airplane first and immediately opens his parachute. His altitude, y, in meters, sfter t seconds is modeled by the equation y=-4t+300. You jump 5 seconds after your friend and free fall for a few seconds. Your altitude, in meters, during this time, is modeled by the equation y=-4.9(t-5)2+300. When do you catch up to your
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
