An artillery shell is fired from the top of a 450-foot ridge with an initial velocity of 860 feet per second. The height of the shell after t seconds is given by the formula: y=−16t2 + 860t + 450 a. Find the height of the shell after 6 seconds. b. What is the maximum height obtained by the shell? c. When will the shell 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.
