First one

 

Center  =  ( -5, - 2)

 

Opens  up and down

 

a  =   8

 

Coordinates of vertices  =   (-5, -2 + 8) and  (- 5, -2 - 8)   =  ( - 5, 6) and ( -5, -10)

 

Slopes of asymptotes   =     ± a / b   =   ± 8 / 6  =  ±  4/3

 

Equations of asymptotes  ...    y + 2 =   ±(4/3) ( x + 5)

Question 2

 

The scale on the  blueprint is  1/10   that of the true dimensions

So....the radius  of the circle on the blueprint  = (1/10) (60) =  6 ft

 

And the center  ofthe crcle is   ( 15,30)

 

So.....the equation of the  flower garden  is

 

(x - 15)^2  + ( y - 30)^2   =  6^2

 

(x - 15)^2  + ( y - 30)^2  =  36
