A cannon ball is launched into the air with an upward velocity of 107 feet per second, from a 12-foot tall cannon. The height hh of the cannon ball after tt seconds can be found using the equation h=−16t2+107t+12h=-16t2+107t+12.a.Approximately how long will it take for the cannon ball to be 55 feet high? Round answers to the nearest tenth if necessary. b.How long long will it take 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.
