n object is launched at 15 meters per second from a 50-meter tall platform. The equation for the objects height h at time t seconds after the launch is h(+)=-4.9t^2+15t+50, where h is in meters. Round answers to 2 decimal places. A- how long will it take for the object to reach it's maximum height? B- what will the maximum height of the object be? C- how long will it take the object to hit the ground?
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.
