Answer:

(x+9)^2+(y+5)^2=81

Step-by-step explanation:

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

(h,k)=center

r=radius

so if you just insert the center (-9,-5) and the r with 9

(x-(-9))^2+(y-(-5))^2=9^2

(x+9)^2+(y+5)^2=81

Hope that helps :)

the ship is moving south at a speed of 24 mi/h

so, firstly, we will draw diagram

so, we have

$OW=4$

$OS=24$

now, we can use Pythagoras theorem

$SW^2=OS^2+OW^2$

now, we can plug values

and we get

$SW^2=24^2+4^2$

$SW=24.33$

so,

the speed of the woman relative to the surface of the water is 24.33 mi/h .......Answer
