geometric probability are probability Q related to geometric figures. Example: a game in county fair - u throw a bean bag onto a square board w/ 1 big blue circle n 1 smaller red circle inside the blue circle. u win a small prize if bean bag lands in blue and a big prize if its in red.

assume bean bag always lands on the board, the probablity of winning a small prize=P(bean lands in blue)

=(Area of blue circle - Area of red circle)/Area of square

During a football game, someone drops a ball from a blimp above. it lands within the playing field which is rectangular in shape with 100 yards in middle and 10 yards for end zone at each end.

Prob(ball land in end zone) = length of end zones / total length of field

= (10+10)/(100+10+10)

=20/120

=1/6

Irrational conjugate theorem

podryga [215]

Answer:

The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.

Step-by-step explanation:

For example, if we consider a quadratic equation x² + 6x + 1 = 0, then two of its roots are - 3 + √8 and - 3 - √8 and they are conjugate of each other. (Answer)

The center of the circle is (h,k) = (-2,-3)

The radius of the circle is r = 2

The standard form of equation of the circle is

${(x + 2)}^{2} + {(y + 3)}^{2} = 4$

<h3>How to find the center, radius and standrad form of the circle?</h3>

The general form of equation of the circle is

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

Here, (h,k) means centre of the circle.

r means radius of the circle.

given that coordinate points of centre of circle is (-2,-3).

Hence the (h,k) = (-2,-3)

<h3>How to find the radius of the circle?</h3>

Now to find the radius of the circle

The distance from a circle's centre to its circumference is its radius.

The distance from a circle's centre (-2,-3) to its circumference (0,-3) is its radius.

using the formula, distance between the two points to obtain radius.

$d = \sqrt{(x1 - x2) {}^{2} + {(y1 - y2)}^{2} } \\ r = \sqrt{ {( - 2 - 0)}^{2} + {( - 3 - ( - 3))}^{2} } \\ r = \sqrt{ {( - 2)}^{2} + {( - 3 + 3)}^{2} } \\ r = \sqrt{ {4}^{2} + 0 } \\ r = \sqrt{4} \\ r = 2$
