k=hj
do u mean to make subject of k
Answer:
B
Step-by-step explanation:
you can figure this out by replace the x and y with any one of the x, y positions and if the answer is 1 it's correct.
I tried 0^2/16+3^2/9 and I got 1.
I tried this with the first two but they didn't work.
The standard equation for a circle with center at (h,k) and radius r is
(x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle.
The formula for the circumference of a circle is C = 2pi*r. In this particular problem, we need to determine the radius of the circle. That radius is: r = C/[2pi]. Here, C = 22pi, so we get r = 22pi/[2pi], and so r^2 = 11^2.
Putting to use the given info, we have:
(x+14)^2 + (y-5)^2 = 11^2
Answer: 10 seconds
Step-by-step explanation: The time it takes is exactly double its swing. 5 times 2 = 10
