The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√

, where h

is the height (in feet) above the transmitter.

Estimate the maximum distance x

(in nautical miles) between the plane that is receiving the signal and the transmitter. Round your answer to the nearest tenth.

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

to complete this square you have to rotate about the origin 270 degrees clockwise.
