Identify the center and radius of a circle with equation (x+4)^2+(y-2)^2=36

Answers

In the equation of a circle in the form (x-h)^2 + (y-k)^2 = r^2, (h,k) is the center and r is the radius.

So, the center of the circle is at (-4,2) with radius 6 units.

​ a(1)= 3 5 ​ a(n)=a(n−1)⋅(−9) ​ What is the 3^{\text{rd}}3 rd 3, start superscript, start text, r, d, end text, end superscript term in the sequence?

Answers

Answer: -630

Step-by-step explanation:

Given the nth term of a sequence;

​a(n)=a(n−1)⋅(−9) and the first term of the sequence a(1) as 35, the third term of the sequence can be gotten by using the formula at when n = 3

If n = 3 and a(1) = 35;

a(3) = 35(3-1)•(-9)

a(3) = 35×2×-9

a(3) = 70×-9

a(3) = -630

There the 3rd term of the series will give us -630 according to the nth term of the formula given.

Final answer:

The problem is about a recursive sequence where each term is the previous term multiplied by -9. After applying this rule twice, it is found that the 3rd term of the sequence is 243.

Explanation:

The problem provided indicates a recursive sequence, where each term is based on the previous term. The sequence is defined as a(1) = 3 and a(n) = a(n - 1) ⋅ (−9), which essentially means that each subsequent term is the previous term multiplied by -9.

To find the 3rd term, we apply this rule twice starting from the first term:

a(2) = a(1) * (-9) = 3 * (-9) = -27

a(3) = a(2) * (-9) = -27 * (-9) = 243

Therefore, the 3rd term of the sequence is 243.
