You collect coins. One of your favorite coins is a silver-colored coin showing a
man's portrait. The radius of the coin is
12 millimeters. What is the diameter of
the coin? What is the circumference of the
coin? What is the area of the coin?

x=25tan30=14.43 or the answer is b

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.
