The eq of the circle in standard form is x^2+y^2+2ux+2vy +d=0 where (-u,-v) is the centre and sq root of u^2+v^2-d is the radius
Answer:
Step-by-step explanation:
Convert this Quadratic Equation to Vertex Form by completing the square, :
So as you can see, each time we broke the equation down, we used the formula to complete the square.
** In the Vertex Formula, −h gives the OPPOSITE terms of what they really are, so do not forget it.

X=5
because right angle is 90 degrees
<span><span>The area of any circle is (pi) x (radius squared).</span>
The radius is of the table 1/2 of the diameter . . . That's 6 feet.
If the table were a full circle, its area would be (pi) x (6 squared) = 36 pi square feet.
But it's only half of that . . . 18 pi = (18) x (3.14) = <u>56.52 square feet</u>.
Is that enough help ?</span>
Answer:
Yes
Step-by-step explanation:
A statistical question is one that can be asked and expected to receive answers that may vary - in other words, where the data from each participant is different.
Here, the question is "How many times did you ride the Ferris wheel today?” Obviously, it's almost impossible that each person asked rode the Ferris wheel the same number of times. Some people may say "once", others may say "three times", and still others might not have ridden it at all.
Given the differences in all these answers, we can say that this IS a statistical question.
Hope this helps!
