To define a perpendicular rays, we first define a ray.

A ray starts from one point and extend it to form one direction.

If two lines or rays or line segments intersect at right angle (90°), then they are perpendicular.

In particular, Perpendicular rays are rays that intersect to form a right angle.

Four right angles are formed in the perpendicular rays.

Step-by-step explanation:

for  a quadratic equation of the form ax^2 + bx + c = 0 the solutions are

x_{1,2}=\frac{-b±\sqrt{b^{2}-4ac } }{2a}

x=\frac{-2+\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4}+ i\frac{\sqrt{19} }{4} \\x=\frac{-2-\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4} -i\frac{\sqrt{19} }{4}

You draw two cards without replacement from a standard deck of 52 cards. What is the
nikdorinn [45]

Answer: 4/663

Step-by-step explanation:

There are 4 6s and 4 7s, so the probability of getting a 6 on the first draw is 4/52 or 1/13. After the first draw there are 51 cards remaining (given your no replacement assumption), and there are 4 7s, so the probability of getting a 7 is 4/51.

The overall probability is

1/13 x 4/51 = 4 / 663
