A circle whose equation is (x-5)^2 + (y+1)^2=36 has a center,C and a radius, r, of

mamaluj [8]

Answer: The center is (5,-1) and radius is 6.

Step-by-step explanation: The equation: (x-h)^2+(y-k)^2=r^2 is really important. Since we have 36 equal r^2, square root it to get 6. And the center would be 5, because (x-5) but do the opposite operation, same for y+1.

An arithmetic sequence has this recursive formula:

maxonik [38]

An arithmetic sequence can be expressed as explicitly or recursively

The explicit formula of the sequence is $a_n = 11 - 4n$

<h3>How to determine the explicit formula</h3>

The recursive formula is given as:

$a_n = a_{n -1} - 4$

$a_1 = 7$

Substitute 2 for n in $a_n = a_{n -1} - 4$

$a_2 =a_1 - 4$

This gives

$a_2 =7 - 4$

$a_2 =3$

Calculate the common difference (d)

$d = a_2 -a_1$

$d = 3- 7$

$d = -4$

The explicit formula is then calculated as:

$a_n = a_1 + (n - 1)d$

This gives

$a_n = 7+ (n - 1)*-4$

Expand

$a_n = 7+4 - 4n$

$a_n = 11 - 4n$

Hence, the explicit formula of the sequence is $a_n = 11 - 4n$
