Use the data in the table to express the value of the nth term of the arithmetic sequence as a function of n. Then use that formula to find the twelfth term of the
sequence.

A) f(n) = 1 + 6(n - 1); 67
B) f(n) = 6 + 7(n − 1); 83
C) f(n) = 6 + (n - 1); 17
D) f(n) = 6 + 6(n - 1); 72

What is the vertex form of f(x) = x2 + 6x + 3

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
