Answer:
C ) circle
This equation represents circle
x²-2 x+y²+4 y - 31 =0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
let P(x₁ , y₁) be the locus point
Let P(x₁ , y₁) and A(1,-2)
Given data PA = 6
PA² = 6²
( x₁ -1 )²+(y₁+2)² = 36
x₁²-2 x₁+1+y₁²+4 y₁ +4 = 36
x₁²-2 x₁+y₁²+4 y₁ = 36-5
x₁²-2 x₁+y₁²+4 y₁ - 31 =0
This equation represents circle
x²-2 x+y²+4 y - 31 =0
The area of the cross section of the column is 
Explanation:
Given that a building engineer analyzes a concrete column with a circular cross section.
Also, given that the circumference of the column is 
meters.
We need to determine the area of the cross section of the column.
The area of the cross section of the column can be determined using the formula,
First, we shall determine the value of the radius r.
Since, given that circumference is meters.
We have,
Thus, the radius is
Now, substituting the value in the formula , we get,
Thus, the area of the cross section of the column is
X = 2 would be the answer??? I'm confused at what it's asking
Answer:
This type of probability is called theoretical probability.
Theoretically, you should be able to draw a 10 of spades 1 out of 52 times, which makes the probability 1/52.
The other main type of probability is experimental probability, which means if you draw 52 cards and draw the 10 of spades 8 times, the theoretical probability is still 1/52, but the experimental probability is 8/52.
