Suppose NASA launches a rocket and that its height, in meters above sea-level, tt seconds after launch is given by h=−4.9 t2+229 t+283h=-4.9 t2+229 t+283 Assuming the rocket will splash down into the ocean, how long after launch does that occur? The rocket splashes down after seconds. How high above sea-level does the rocket get at its peak? The rocket peaks at meters above sea-level. Round your answers to the nearest whole number. Hint: Splashdown occurs at an x-intercept. The maximum height occurs at the vertex.
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.
