-6 = r cos α and -8 = r sin α
r = sqrt( 6^2 + 8^2) = sqrt 100 = 10
α = arctan ( -8/-6) = arctan (4/3) = 53.13 degrees
polar firm = r ( cos α + i sin α)
= 10(cos 53.18 + i sin 53.18)
its been a long time but ui think thats correct
Answer:
Option D.
Step-by-step explanation:
The vertex form of a parabola along y-axis is
...(1)
where, (h,k) is vertex and a is a constant.
From the given graph it is clear that the vertex of the parabola is (0,2). So, h=0 and k=2.
...(2)
The graph passing through (6,5). Substitute x=6 and y=5 in the above equation.
Substitute
in equation (2).
Therefore, the correct option is D.
