Step-by-step explanation:
Answer:
The chord is bisected ⇒ 3rd answer
Step-by-step explanation:
* Lets revise some facts in the circle to solve the problem
- A chord in a circle is the segments whose endpoints lie on the
circumference of the circle
- A diameter of a circle is a chord passes through the center of the
circle
- The diameter is the longest chord in the circle
- Any line passes through the center of the circle and perpendicular
to a chord on the circle bisects it
* Lets solve the problem
∵ The diameter of the circle passes through the center of the circle
∵ The diameter intersects a chord of a circle at a perpendicular
∴ The diameter is perpendicular to the chord
∵ Any line passes through the center of the circle and perpendicular
to a chord on the circle bisects it
∴ The diameter bisects the chord
* The chord is bisected
Answer:
−2=−2x^3
Step-by-step explanation:
10x3= 3x2−20x−6=(10x3⋅(3x2))(−20x−6)=−600x6−180x5x2=−600x6−180x5−2x⋅(2x2)=−4x3−2x⋅x2=−2x^3
−2=−2x3
2x^2=−2x^3
−2=−2x^3
Answer:
Step-by-step explanation:
Given:
Given point P(6, 6)
The equation of the line.
We need to find the equation of the line perpendicular to the given line that contains P
Solution:
The equation of the line.
Now, we compare the given equation by standard form 
So, slope of the line 
, and
y-intercept 
We know that the slope of the perpendicular line 
So, the slope of the perpendicular line
From the above statement, line passes through the point P(6, 6).
Using slope intercept formula to know y-intercept.
Substitute point 
and 
So, the y-intercept of the perpendicular line
Using point slope formula.
Substitute and in above equation.
Therefore: the equation of the perpendicular line
