Answer:
1
Step-by-step explanation:
Taking both sides of the equation to the power 3 allows us to get rid of the square root on the left hand side of the equation. On the right hand side 1^3 = 1.
Hence
3x-2=1
3x=3
x=3/3
x=1
3x-2=1
The answer would be the choice at the bottom right corner!
I'm positive the answer is correct! :)
You can work out that K≈2.9262 and then plugging this in gives us θ≈2.34∘
I think it would be letter C
Answer:
The linear speed of the bike is 19.242 miles per hour.
Step-by-step explanation:
If sliding between the bottom of the wheel and ground can be neglected, the motion of the wheel can be well described by rolling, which is a superposition of coplanar pure rotation and translation, The speed of the bike occurs at the center of the wheel, where resulting instantaneous motion is pure translation parallel to ground orientation. The magnitude of the speed of bike (), measured in inches per second, is:
Where:
- Radius, measured in inches.
- Angular speed, measured in radians per second.
Now, the angular speed must be converted from revolutions per minute into radians per second:
The speed of the bike is: ( and )
Lastly, the outcome is converted into miles per hour:
The linear speed of the bike is 19.242 miles per hour.
