CELL PHONES In Exercises 1 and 2, use the following information.

A cellular phone network uses towers to transmit calls. Each tower transmits to a

circular area. On a grid of a city, the coordinates of the location and the radius

each tower covers are as follows (integers represent miles): Tower A is at (0, 0)

and covers a 3 mile radius, Tower B is at (5, 3) and covers a 2.5 mile radius, and

Tower Cis at (2, 5) and covers a 2 mile radius.

1. Write the equations that represent the transmission boundaries of the towers.

Graph each equation.

2. Tell which towers, if any, transmit to a phone located at J(1, 1), K(4, 2),

L(3.5, 4.5), M(2, 2.8), or N(1, 6).

I have a jeep Cherokee sport 1999 its 2 wheel drive only. For some reason when I drive the jeep and press the breaks it makes a shrinking sound from the front wheels and when you press the brakes the jeep stops really fast instead of slowing down. It’s like if you push the brakes even lightly the front wheels lock up. But these effects only last for about five minutes and then it drives and runs fine. What could be the problem here?

my mother has a doge caravan. It was parked for a while and now she is wanting it back on the road. But it is ticking kinda of like the old 4.0 inlines did. But the tick is not the big problem.

Its smokeing some under the hood but i think that is oil burning off from the oil leak, While trying to start it it makes some really horrible sounds mostly it knocks and grunts. What could cause this.

When is the unknown chemical. I flamed tested a unknown and got that its positive ion is potassium but when I tested for the negative ion I got confusing results I ran the tests four times each and made sure there were no cross contamination happening. Here is what I did and the results I got. I first tested with hcl and got nothing. Then I test with bacl2 and got a white precipitate. Then I tested with agno3 and got a pale yellow witch points to iodine being present but the white ppt points to sulfate being present. please help I have to get this lab write up done.

ok how do i go about having a interface with back track. I see youtube vids of people with icons like Google chrome and other progams. When i boot back track from my thumb drive all i can see is the terminal there is nothing eles there so how can i get extra programs.

Would the oxidation of sulfur be faster in larger pyrite chunks or smaller pyrite chunks? Explain how particle size may affect reaction rates.

ok im really green but need help. Here is the problem. The alternator belt on my kia sepctra 2001 broke. I need to replace it but to get to it i have to take off the power staring belt. How do i get the belt to lossen to get off. I cant find the tensioner mostly because i have no ideal what im looking for. If you could somehow find pictures it would really help. I'm very new to this.

i have a kia spectra 2001 and it did something strange today. I was driving and i felt that the transmission was shifting really hard from first gear to second gear. Which was strange but then my speedomtere and tacometer tempture guage and heat stop working and i tried to press the gas and the car cut off and is not starting now it sounds like the battery is dead now. any ideals

i have no time to do all of the independent practices that our teacher gives us is there a data base or websites that has these.The course is ms access

i work at circle k its a gas station well i used to. What happen was a few weeks ago i was accused of talking 15 cartons of cigarettes. i was put on leave for 4 days without pay as the police conducted a investigation. i was found innocent. i returned to work and things were not going right.

The general equation of an ellipse is shown below.

9x2 − 54x + 25y2 − 100y − 44 = 0

• Write an equivalent standard equation for the ellipse.

• Describe what the coefficients of x2 and y2 in the standard equation tell

about this ellipse.
