Answer:
Please see below.
Explanation:
The coordinates of point C are (a+b,c).
The coordinates of the midpoint of diagonal ¯¯¯¯¯¯AC are (a+b2,c2).
The coordinates of the midpoint of diagonal ¯¯¯¯¯¯BD are (a+b2,c2).
¯¯¯¯¯¯AC and ¯¯¯¯¯¯BD intersect at point E with coordinates (a+b2,c2).
By the definition of midpoint, ¯¯¯¯¯¯AE≅¯¯¯¯¯¯CE and ¯¯¯¯¯¯BE≅¯¯¯¯¯¯DE.
Therefore diagonals ¯¯¯¯¯¯AC and ¯¯¯¯¯¯BD bisect each other.
Answer:
80π feet/ second.
Step-by-step explanation:
Angular velocity of a point = 10π radians per second
Radius of the circle is 8 feet.
We know the formula of angular velocity is
Angular velocity = 
10π = 
Speed = 80π feet/ second.
Option C is the answer.
Try plugging them in, might seem tedious, but it's the best way to practice. if you plug in a pair and the left side of the equation is less than or equal to 6, it's the right answer.
The answer 19 because, 19+8=27, then 27 divided by 9 is equal to 3. If you need to know how I got 19 just let me know!
