A rocket is rising at a constant speed of 5 mi/s. A person is filming from their car on a straight road at a speed of 13/12 mi/s. When the car passes directly under the rocket, the rocket is 3 miles above the car. How fast is the distance between the car and the rocket increasing 2 seconds later? (Answer: 5.1 mi/s)
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.
