The equation of a circle in standard form is

where (h, k) is the center of the circle, and r is the radius if the circle.
We need to find the radius and center of the circle.
We are given a diameter, so to find the center, we need the midpoint of the diameter.
M = ((-6 + 6)/2, (6 + (-2))/2) = (0, 2)
The center is (0, 2).
To find the radius, we find the length of the given diameter and divided by 2.





A=20
5a-4=3a+36 (subtract 3a from both sides and add 4 to both sides)
2a=40. Divide 40by 2
A=20
It follows from the definition of the binomial coefficient:

So we have

That is,
gets absorbed into the numerator's factorial, and we introduct
into the denominator. Now,
, so we get

as required.
Yes it is
it’s the 41st term
EXPLANATION:
the nth term would be 15n+35
because the terms go up by 15 and you add 35 to get to the term.
1. 2. 3. 4.
50. 65. 80. 95
1000- 35= 965
965/15=41
27 - 1.5x ≤ 36
