Answer:
m
OR
62.8318531 m
Step-by-step explanation:
This is actually pretty simple
The distance the tip travels is the arc length and the length of the pendulum is the radius of a circle
The formula for arc length is <u>Angle in Radians x Radius</u>
<u></u>
So pi/12 * 4 = pi/3 m
We know this is how much it travels every second so it is going at pi/3 m/s
One minute is 60 seconds
pi/3 * 60 = 20pi m
Answer:
Step-by-step explanation:
You need to used the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you know that Kevin traveled at a constant speed on the highway from Hickory Hills to Chicago in 20 minutes (which is ) and the distance is 17 miles. Then, you can identify that:
Therefore, knowing these values, you can substitute them into the formula. Then, you get:
Answer:
Step-by-step explanation:
For this exercise you need to remember the following Trigonometric Identity:
You must observe the figure given in the exercise.
You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).
So, you can identify in the figure that:
Knowing these values, you can substitute them into :
Now you must evaluate:
Finally, rounding to the nearest hundreth, you get:
