if f(x)=2x+1,what is f(-3)
B) Then center of the circle
C) The chord of the circle
D) The central angle of the circle
Line segment AB, which is perpendicular bisector of the chord CD in the circle, contains center of the circle.
Chord is the straight line sement which is made inside the circle by joining two points of that circle.
The bisector of the chord in a circle is always a passes from center of the circle and is a perpendicular line to that chord.
Hence, line segment AB, which is perpendicular bisector of the chord CD in the circle, contains center of the circle.

Answer:
b the center of the circle. pls madk brainliest.
It will take Jennifer 4 hours to complete her swim along the Charles River at a speed of 9 miles per hour.
Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
We can use the formula:
distance = rate × time
to solve this problem.
Since Joe swam at a speed of 12 miles per hour for 3 hours, his distance is:
distance = rate × time
= 12 miles/hour × 3 hours
= 36 miles
Since Jennifer is swimming the samepath, her distance will also be 36 miles.
We can use the same formula to find how long it will take her to complete the swim:
distance = rate × time
36 miles = 9 miles/hour × time
Solving for time, we get:
time = 36 miles ÷ 9 miles/hour = 4 hours
Therefore,
It will take Jennifer 4 hours to complete her swim along the Charles River at a speed of 9 miles per hour.
