The equation of a circle centered at point (x1,y1) with a radius r is given by

are you sure you wrote down the problem correctly?
1. A 1.0 minute
Range can be calculated by subtracting 3.0 mins - 2.0 mins = 1.0 minute.
2. D. 4
Joel was faster than Gunner in meets 1, 2, 3 and 4.
3. B. 1.75 minutes
Gunner has consistent improvement at intervals of 0.25 minutes per meet. Subtracting 2.0 mins by 0.25 mins we get 1.75 minutes.
Answer: Have a nice day!
Step-by-step explanation:
Angle ABC = 130
Angle ABC = Angle ADC = 130 (Opposite angles are equal)
Angle DAB = 180 - 130 = 50 (consecutive interior angles)
