The formula U = V2.4r models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature r, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 450 feet. What is the maximum safe speed? For this problem, round your answer DOWN to the nearest whole number. (Thínk: Why is this type of rounding appropriate for this scenario?) max safe speed =

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.
