Question

The hospital provides ambulance service within a 30 mile radius of the hospital. If this service area is represented graphically, with the hospital located at (0, 0), what is the equation that represents the service area?

x^2 + y^2 = 900

x^2 + y^2 = 30

(x - 30)^2 + (y - 30)^2 = 0

(x + 30)^2 + (y + 30)^2 = 0

Answer 1

Hint: the equation of a circle is:

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center of the circle and r is the radius

Answer 2

Wouldn't it be answer C, @Vocaloid ?

Answer 3

I thought it was A.

Answer 4

I mean the formula he has shows it right there in C .-.

Answer 5

@Allison if you follow the formula @Vocaloid posted, how did you end up concluding with C as your result?

Answer 6

The formula was there.

Answer 7

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center of the circle and r is the radius ....

What does 30 represent in terms of given equation?
What does (h,k) represent in the given problem?

Answer 8

30 is miles.
H is hospital?
K is I don't know..?

Answer 9

Okiee?

Answer 10

What are the values of h and k in this case?

Answer 11

Hospital?

Answer 12

If this service area is represented graphically, with the \(\textbf{hospital}\) located at \(\textbf{(0, 0)}\), what is the equation that represents the service area?

Answer 13

Math Processing Error is all I see.

Answer 15

There

Answer 16

A?

Answer 17

you could have bolded it with the bold command ya know... and it loaded fine for me ._.

sometimes that happens ._.

Answer 18

Happened on OS from time to time to

Answer 19

where LaTeX would break because they published a update to it, and they couldn't do a thing but wait.

Answer 20

(for the people who update latex to fix it)

Answer 21

I don't think this particular issue is a LaTeX issue.

Answer 22

A is correct @Allison. Thanks for taking the time to answer this question. Hope you enjoy your summer.

Answer 23

Thanks. You too.
