Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
Answer:
3 r 4
Step-by-step explanation:
22/6= 3.6 recurring so we round down (3.6 → 3)
so 3 remainder 4.
The remainder means left-overs known as 'r'.
I think that it might be "c" but I am not sure but hey it is worth a shot sorry if I am wrong!
