Answer:
See below.
Step-by-step explanation:
1)
So we have the limit:
This is equivalent to:
To solve, we can use the following property:
Therefore, our limit is the same as:
We are already given that the limit as x approaches 4 of g(x) is -2. Therefore:
You simply need to evaluate this to solve the limit. I don't have enough information to solve this, so maybe you have something more.
Similarly, for the second one:
2)
We have:
Using the same property:
And we are told that this is 16, so:
And we just need to evaluate this to find the limit.
I hope you find this helpful!
Answer: es la c) 1d,2a,3b,4c
Step-by-step explanation:
Question 1:
------------------------
Total points = 100
Total question = 40
Type of questions : 2-points question and 4-points questions
Assumed all 40 questions are 2-points questions.
Total points = 40 x 2 = 80
Difference in points = 100 - 80 = 20 points
Difference in the 2 type of questions = 4 - 2 = 2
Number of 4 marks questions = 20 ÷ 2 = 10
Number of 2 marks questions = 40 - 10 = 30
Answer: There are 10 4-marks questions and 30 2-marks questions.
------------------------------------------------------------------------------------------------
Question 2:
------------------------
Let x be the number of offices you need to clean.
Total cost = 315 + 4x
Total revenue = 25x
To break even,
315 + 4x = 25x
21x = 315
x = 15
Answer: You need to clean 15 offices to break even.
------------------------------------------------------------------------------------------------
Question 3:
------------------------
Total distance (including return trip) = 255 + 255 = 510 miles
Total time taken = 1.7 + 1.5 = 3.2 hours
Speed = Distance ÷ time
Speed = 510 ÷ 3.2 = 159.38 miles/hour
Answer: The average speed is 159.38 miles/hour
There are four terms and it is sum !
so the answer is C !!
