What is the equation of a circle with center (8,1) and radius 6?
A. (x - 3)2 + (y - 1)2 = 6
B. (x - 3)2 + (y - 1)2 = 36
C. (X + 8)2 + (y + 1)2 = 36
D. (X + 8)2 + (y + 1)2 = 6

(x - 8)² + (y - 1)² = 36

None of the above

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

(x - 8)² + (y - 1)² = 6²

(x - 8)² + (y - 1)² = 36

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
