Completing the squares, the correct statements regarding the equation of the circle are given by:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center and radius r is given by:
In this problem, the equation is given by:
x² + y² - 2x - 8 = 0.
Completing the squares:
(x - 1)² + y² = 8 + 1²
(x - 1)² + y² = 9.
Hence the center is (1,0), the radius is 3, and the correct statements are:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

In a parallelogram, opposite sides have the same length.
3x + 9 = 5x -5
group like terms on one side
9 + 5 = 5x -3x
14 = 2x
x is 7.
Since AB is 5x -5
AB = 5(7) -5
AB = 30.
BX is half of the line DB. So BX = DX
5y = 7y - 10
10 = 7y -5y
10 = 2y
y =5.
Since BX = 7y - 10
BX = 7(5) -10
BX = 25
Answer:
Step-by-step explanation:
Recall that the probability of event A , given that event B has occurred is given as:
Since P(A|B) = 0.08 and P(A) = 0.40 are not the the two events are not independent.
We substitute the probabilities to get:
Therefore
Answer: 172.5% OR 1.725 as decimal
Step-by-step explanation:
138-80=58
80=100% OR 1
58=x%
x=58/80
x=72.5% OR 0.725
58=72.5
1+0.725=1.725
80x1.725=138
Hopefully I somehow helped :) -KJ
