The formula v = √ 2.4 r v = 2.4 r models the maximum safe speed, v v , in miles per hour, at which a car can travel on a curved road with radius of curvature r r , in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 340 feet. What is the maximum safe speed?

You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
