Complete question:
A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute.
Calculate the angle subtended at the centre by the minor arc after 1 second.
Answer:
the angle subtended at the centre by the minor arc is 30⁰
Step-by-step explanation:
Given;
radius of the wheel, r = 10 cm = 0.1 m
angular speed of the when, ω = 5 rev/min
duration of the motion, t = 1 second
Determine the angular speed in radian per second,
After 1 second, the angular distance turned by the wheel is calculated as;
Therefore, the angle subtended at the centre by the minor arc is 30⁰
For this case we have:
Be a function of the form
Where:
If we want to find f (-2), we substitute , then:
Since we have a negative root, the result will be given by complex numbers. By definition:
So:
Answer:
1) yes. the constant rate of change is 3/1
2) no
3) yes. constant change is 2/1
2. 4 77/100
3. 10.7
4. 6 57/100
The answer the the graph is -2x^2.
