Collar Receiver
please help me with this foul word algebra problem?
States: a wildlife researcher is the supervision of a black beaer having a radio telemetry collar with a transmission range of 28 miles. the investigator in a research station with its receptor and monitoring Bear movements. if we put the origin of a coordinate system in the research center, which is the equation of all possible locations of the bear in the transmitter would be at its maximum range?
A: x ^ 2 + y ^ 2 = 28 ^ 2 EXPLANATION: This is a kind of disgust (tenor) problem, but I think it's mask a very simple question: Basically, the bear can go 28 miles and still be within the range of monitoring, but once you put any addition, no tracking anymore. Therefore, the image of the monitoring station as a point, and pretend that the bear has a (huge!) belt is 28 m. long and attached to the station. If the bear moves as far as you can to pull the belt tight, after 28 m. away. Now, imagine that the bear keeps walking, but is subject to the belt, so just to go in a big circle. (Have you ever a dog tied to a tree? You know what I mean) The equation of a circle is ^ 2 + y ^ x ^ 2 = r 2, where r = radius of the circle belt extends from 28m, that is our radio. Now, the bear is not really with a belt, which has a wireless tracking collar, but is the same idea. For the bear to be as far as possible, but still in range tracking, which must be exactly 28 m. away. All points where it could be 28m away are exactly like all the points where you could pull a tight strap 28m – form a circle. So x ^ 2 + y 2 = 28 ^ 2 (and you can work out square 28 if desired)
