The equation for a circle with a center (-2, 8) and a radius of 9 will be (x + 2)² + (y − 8)² = 81.
<h3>What is an equation of a circle?</h3>
A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x - h)² + (y - k)² = r²
Write an equation for a circle with a center (-2, 8) and a radius of 9.
Then the equation will be
(x + 2)² + (y − 8)² = 9²
(x + 2)² + (y − 8)² = 81

Answer: .05
Step-by-step explanation: 3.60 divided by 12: 0.3
5.00 divided by 20: 0.25
0.3-0.25=0.05
Since the 2 and x^1/4 are multiplying we can do the math separately and then just multiply them afterwards
2^-4 is the same as 1/(2^4) which is 1/16
(x^1/4)^-4 (POWER RULES REVIEW)
2 exponents of same base you just add (basically multiply the two)
so x^(1/4x-4) = x^(-1)
which is just 1/x
so the answer is 1/16x
