square roots

1. Simplify the expression: V Enter your answer as a reduced fraction or a terminating decima 2. Evaluate each expression, or state that the expression is not a real number by entering DNE. V - 16 3. The formula v=v2.6r 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 700 feet. What is the maximum safe speed? For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?) max safe speed = 4.
