Answer:

cos0 = 6.8556546i/23 or sqrt-47/23

Step-by-step explanation:

hypotenuse is 23, opposite is 24

we have to find the adjacent using the pythagorean theorem

24^2 + b^2 = 23^2

576+b^2=529

subtract

b^2=-47

b=sqrt-47

sqrt of -47 is 6.8556546i, there is an i since it is the square root of a <em>negative</em>

cos = adjacent/hypotenuse

The point (- 3, 6) is on a circle with a center at (2, 3) What is the equation of the circle?

anzhelika [568]

Answer:

$(x - 2)^{2} + (y - 3)^{2} = 36$ is the equation of the circle

Step-by-step explanation:

$(x - h)^{2} + (y - k)^{2} = r^{2}$ where (h, k) is the center and r is the radius

In this case h = 2 and k = 3 and r = 6 (see below)

r adius =

$\sqrt{(2 + 3)^{2} + (3 - 6)^{2} } \\= \sqrt{5^{2} + (-3)^{2} } \\= \sqrt{25 + 9\\}\\ = \sqrt{36} = 6$

Therefore, $(x - 2)^{2} + (y - 3)^{2} = 36$ is the equation of the circle
