URGENT!! NEED THIS IN TWO HOURS. DUMB ANSWERS WILL BE REPORTED ALTHOUGH I UNDERSTAND IF YOU MAKE A SIMPLE MISTAKE IN YOUR CALCULATIONS. I NEED THE FULL ANSWER AND EXPLANATION BELOW

Write the general equation for the circle that passes through the points (- 5, 0), (0, 4), and (2, 4).

You must include the appropriate sign (+ or -) in your answer. Do not use spaces in your answer.

4x^2 + 4y^2 x y = 0
ANSWERS MUST BE A ROUND NUMBER

Yo sup??

given points are (-5,0),(0,4) and (2,4)

the given equation is

4x²+4y²+ax+by=0

let us plug in the point (-5,0) in the equation

4*(-5)²+0-5a+0=0

a=20

let us now plug in the point (0,4) in the equation

0+4*4²+0+4b=0

b=-16

therefore the final equation is

4x²+4y²+20x-16y=0

Hope this helps

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
