Im thinking the Earth’s energy from the Sun arrives in the form of visible and invisible light
From my knowledge, I know that cos(30) = ((2)^(1/2))/2, therefore 9cos(30) = 9((2)^(1/2))/2
X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
r=8
