I need help ASAP!!! Please explain how to solve the problem I am stuck

Kazeer [188]

Answer:

( x - 11 )^2 + ( y - 5 )^2 = 4^2

Step-by-step explanation:

The general form of equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2.

h and k are the co-ordinates of the center of circle and r is the radius

We have,

r=4

(h,k)=(11,5)

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

or, ( x - 11 )^2 + ( y - 5 )^2 = 4^2

If you simplify,

x^2-22x+121+y^2-10y+25=16

or, x^2+y^2-22x-10y+146-16=0

or,x^2+y^2-22x-10y+130=0

Two roads that cross at right angles are used as the coordinate axes for a city map. A hospital is located at the point (−1.25,

Amanda [17]

We know that

The two roads are the x axis coordinate and y axis coordinate

therefore

if A hospital is located at the point (−1.25, −5.5)
the distance of hospital from x axis coordinate is the y coordinate---> 5.5 units
the distance of hospital from y axis coordinate is the x coordinate -->1.25 units

the answer are
the distance of hospital from each road is 5.5 units and 1.25 units
