Answer:
u = (18, 36, 2)
Step-by-step explanation:
Given:
- v=(4,-3,5)
- w=(2,6,-1)
- z=(3,0,4)
and u = 6w+2z
Putting the values of v,w and z in u, we have:
u = 6(2,6,-1)+ 2(3,0,4)
<=> u = (12, 36, -6) + (6, 0, 8)
<=> u = (12+6, 36+0, -6+8)
<=> u = (18, 36, 2)

Answer: A
Explanation:
Because the center of circle A is (0,1) and circle B is one unit down, it would be x^2+y^2=1 because the center of circle B is (0,0). (The equation for a circle is (x-h)^2+(y-k)^2=r^2 with h and k as coordinates of the center of the circle and r as the radius.)
