a.
To draw a diagram showing where the bear might be when all three rangers can receive signal.
a.
Explanation of Solution
Given:
A mini-radio transmitter has been secured to a bear. Rangers D,E , and F are studying the bear’s movements. Rangers D and E can receive the bear’s beep at distances up to 10 km, ranger F at distances up to 15 km.
The bear must be located in the center point of all three rangers for all three rangers to receive the signal.
Conclusion:
Therefore, the bear is located on the center of all three rangers.
b.
To draw a diagram showing where the bear might be when ranger F suddenly detects the signal after a period of time during which only rangers D and E could receive the signal.
b.
Explanation of Solution
Given:
A mini-radio transmitter has been secured to a bear. Rangers D,E , and F are studying the bear’s movements. Rangers D and E can receive the bear’s beep at distances up to 10 km, ranger F at distances up to 15 km.
The bear will be just on the borer of
Conclusion:
Therefore, the bear will be on the border of
c.
To draw a diagram showing where the bear might be when ranger D is off duty, and ranger F begins to detect the signal just as ranger E loses it.
c.
Explanation of Solution
Given:
A mini-radio transmitter has been secured to a bear. Rangers D,E , and F are studying the bear’s movements. Rangers D and E can receive the bear’s beep at distances up to 10 km, ranger F at distances up to 15 km.
The bear will be around the place of ranger D when ranger D is off duty, and ranger F begins to detect the signal just as ranger E loses it.
Conclusion:
Therefore, the bear will be at the place of ranger D .
