The vertex of the parabola below is at the point (1,3), and the point (2,6) is
on the parabola. What is the equation of the parabola?
O A. y=3(x+ 1)2-3
O B. y=3(x-1)2 + 3
O c. x= 2(y - 3)2 + 1
O D. y=6(x-1)2 + 3

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
