Answer:
x^2 + y^2 - 4x + 6y - 3 = 0
Step-by-step explanation:
(x-a)^2 + (y-b)^2 = r^2 is the equation of a circle which has center point (a,b) and radius r.
So in this question (2,-3) is the center and r=4.
Then we can write the equation as,
(x-2)^2 + (y+3)^2 = 16
x^2 + y^2 - 4x + 6y - 3 = 0
That is the Equation of the circle.

Answer: 1/16
Step-by-step explanation: It's important to understand that the two spins are called independent events because the outcome of the first spin does not affect the outcome of the second spin.
To find the probability of independent events, we first find the probability of each event, then we multiply the probabilities together.
Since there is one 4 on the spinner and four possible outcomes, each of which is equally likely, the probability of spinning a 4 is 1/4.
This mens that 1/4 is the probability of
getting a 4 on the second spin too.
Now we multiply.
1/4 x 1/4 gives us 1/16.
So the probability of spinning a 4 twice is 1/16.
