Answer:
Step-by-step explanation:
Review the standard equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
A point on (4, -2) has the radius r^2 = (4)^2 + (-2)^2, or r^2 = 20, or r = 2√5. Knowing the center is at (0, 0), we can write:
x^2 + y^2 = 20, or x^2 + y^2 = (2√5)^2
Answer: hey
Step-by-step explanation:
The answer to this question is 4.37 for 3 nights and 13.4 for 10 nights
Take your original equation
and multiply both sides by to remove the fractions. You are left with
So,
Update: There is no numerical answer that can be found without being given a value for either x or y
