The tangent function gives the ratio of vertical to horizontal distance in this case.
.. vertical distance = (horizontal distance)*tan(angle of depression)
.. = (40 m)*tan(50°)
.. vertical distance ≈ 47.7 m
A circle equation always looks like this
(X-h)^2 + (y-k)^2 = r^2
Now take the square root of both sides and you get r=
Answer:
so, i am pretty sure all this is saying is move the plot nine units down the y axis. so you'd plot (5, 7).
Step-by-step explanation:
i hope this helps, let me know if this is right.
