When a line is a tangent to a circle then the point of a tangent on a circle is perpendicular and also equal to the radius
So for perpendicular.

4y + 3x - 44 = 0
So, a = 4
b = 3
c = -44
x = 5
y = 1
Putting the values in the formula, we get
P = -4.2
Since the radius of the circle 5 is not equal to P, The line is not a tangent to the circle.
Answer: omg this is hard
Step-by-step explanation:
Answer:
18/20π
Step-by-step explanation:
81π ÷ 1 = 81π
81π ÷2 = 18/20π
You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.
There are
ways of picking 2 of the 10 available positions for a 0. 8 positions remain.
There are
ways of picking 3 of the 8 available positions for a 1. 5 positions remain, but we're filling all of them with 2s, and there's
way of doing that.
So we have

The last expression has a more compact form in terms of the so-called multinomial coefficient,

Answer:
Answer in the picture: x = 1 | y = -5
Step-by-step explanation:
Not sure if that's the answer you're looking for but I think that's it
