A small island with a lighthouse is located 20 miles east and 30 miles North of City A. From the lighthouse you can see 10 miles in every direction.
b) Write an equation for the circle that marks as far as you can see from the lighthouse
c) If the boat travels at 10 miles per hour and leaves City A at time = 0, when and where
will you first be able to see the red boat from the light house? (What is the coordinate?
And the time?)
d) When and where will you lose sight of the red boat from the light house? (What is the
coordinate? And the time?)
