Answer:
This approach to (0,0) also gives the value 0
Step-by-step explanation:
Probably, you are trying to decide whether this limit exists or not. If you approach through the parabola y=x², you get

It does not matter if x>0 or x<0, the |x| on the denominator will cancel out with an x on the numerator, and you will get the term x²/(√(1+x²) which tends to 0.
If you want to prove that the limit doesn't exist, you have to approach through another curve and get a value different from zero.
However, in this case, the limit exists and its equal to zero. One way of doing this is to change to polar coordinates and doing a calculation similar to this one. Polar coordinates x=rcosФ, y=rsinФ work because the limit will only depend on r, no matter the approach curve.
It would be 63, because 33 1/3% is the equivalent of 1/3,
21x3 = 63
Answer:
a. See attachment below
b. 613 people
c. Categorical
Step-by-step explanation:
a. View attachment below
b.
Given
Total Number of People Surveyed = 1021
X tax return by professional / Number of People Surveyed = 60%
X tax /1021 = 0.6
X tax = 0.6 * 1021
X tax = 612.6
X tax = 613------ Approximated
So, the number of people used an accountant or professional tax preparer are 613.
c.
The data for preparing a tax return will be considered as categorical as the methods for a person to file his/her tax returns are categorized into four which are:
1.Electronically
2.Manual preparation
3.Online tax service
4.Use of software tax program
Yes, the correct answer is A because you're multiplying 5 by the expression (N+15)
