- A state patrol officer saw a car start from rest at a highway on-ramp. She radioed ahead to another officer 29mi along the highway. When the car reached the location of the second officer 28 min later, it was clocked going 60 mi/hr. The driver of the car was given a ticket for exceeding the 60 mi/hr speed limit. Why can the officer conclude that the driver exceeded the speed limit?Interval [0,2pi]how do you find the values of x that satisfy the definition of absolute value for the given value and the given absolute deviation
