1.25pi ft/sec
80pi ft/sec
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.
Answer:
Step-by-step explanation:
Formula : (1)
We are given that , The angular velocity of a point with radius 8 feet is 10 pi radians per second.
i.e. Radius = 8 feet
Angular velocity = radians per second.
Then, the speed of the point will be :-
[using (1)]
Hence, the speed of the point
Answer:
Step-by-step explanation:
1. Supplementary
2. complementary
3. neither
4. These two are vertically opposite so neither.
5. Supplementary
6. They add to 90 so they are complementary
7. They add to 180 so they are supplementary.
8. These 2 are equal and vertically opposite. They are neither for this exercise.
9. Complementary: they add to 90.
Answer:
7 miles your friend run each day.
Step-by-step explanation:
As per the statement:
You run mile each day.
⇒ you run each day = miles.
It is also given that; Your friend runs 4 times as far as you do.
"4 times as far as you do" means miles
⇒ Your friend runs each day = 7 miles.
therefore, 7 miles your friend run each day
