An object is thrown upward at a speed of 143 feet per second by a machine from a height of 6 feet off the ground. The height hh of the object after tt seconds can be found using the equation h=−16t2+143t+6h=-16t2+143t+6 When will the height be 160 feet? When will the object reach the ground? List all of the solutions with commas between them. Round to one decimal place.
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.
