The circle below is centered at the point (4, -3) and has a radius of length 3.
what is its equation?
а. (x-3)2 + (y+ 4)2 = 9
в. (x-3)2 + (у- 4)2 = 9
с. (х+4)2 + (у - 3)2 =
22
d. (x-4)2 + (y+ 3)2 =
32

The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2

where h and k is the center point and r is the radius.

Using the center point and radius given the equation becomes:

(x-4)^2 + (y+3)^2 = 3^2 or (x-4)^2 + (y+3)^2 = 9

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
