Suppose a car is traveling down the highway at a constant rate odt 60 miles per hour. It passes a police car at the side of the road. To catch up to the car, the police officer accelerates at a constant rate. The distance d (in miles) the poluce car has traveled as a function of time t (in hours) since the other car has passed it is given by d=3600t^2. Write and solve a system of equations to calculate how long it takes the police car to catch up to the other car.​

What is the expression in factored form? -x^2 + 3x + 28 a. (x-7)(x-4) b. -(x-7)(x+4) c. (x+4)(x+7) d. -(x-4)(x+7)

What is the difference between the equations of a vertical and a horizontal line?

(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.)
