a) (x+6)^2-25
b) (-6, -25)
Step-by-step explanation:
Perfect square trinomial! If you have 12x, divide by two and get 6, so we have (x+6)^2+q. Then solve for q. You get q as -25.
For b, we just take the vertex from vertex form. We get x+6=0 so x=-6, and q = -25, so the answer is (-6, -25).

1/3 x pi x radius squared
1/3 x pi x 0.7225 = 0.7566002307
0.76 to nearest hundredth
Well first you need to change minutes to hours (240 min=4 hours, 240/60 min). Then you would just multiply 70 km by 4 hours to get 280 km.
