Answer:
10% increase
Step-by-step explanation:
THe original quantity is 10
The new quantity is 11
We need to find the percentage increase.
Percentage increase is found by finding the increase (New - Old) and dividing the answer by the old value (original value). Then we multiply by 100 to get the percentage.
The change is: 11 - 10 = 1
Now, dividing by old, we get: 1/10
Now, multiplying by 100, we get the percentage: (1/10) * 100 = 10%
So, from 10 to 11, there is a 10% increase
The last choice is the right answer. Curves do not have a constant rate of change.
Answer: 2041 meters
A bicycle wheel is a circular object.
The circumference of a circle is 2π(radius)
Here given:
- radius = diameter/2 = 65/2 = 32.5 cm
Hence find the length for each revolution:
- 2π(32.5) = 204.1 cm per revolution
Then for 1000 revolutions:
- 204.1 × 1000 = 204100 cm ≈ 2041 meter
Answer:
You have not given any detail about the cylinder like radius diameter or height.
The correct answer is C.
The limit in A does exist:
The limit in B also exists: for any ,
But this alone does not prove the 2D limit exists. only captures all the paths through the origin that are straight lines.
The limit in C also exists, but it's not the same as either of the limits along the paths used in A and B.
That this value is non-zero tells us the original limit does not exist.
The claim in D is generally not correct. That is undefined does not automatically mean the limit doesn't exist. A simpler example:
yet is undefined.
