The formula v=√2.3r=models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature rr, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 510 feet. What is the maximum safe speed? Give your answer to two decimal places. Max safe speed =
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.
