Which statement describes the sequence defined by an
n3 +3?
n2-60
O The sequence diverges.
O The sequence converges to a limit of 0.
O The sequence converges to a limit of infinity
O The sequence converges to a limit of - infinity
Answer:
C
Step-by-step explanation:
To find the statement that describes the sequence, we find it's limit as n goes to infinity.
Doing this, as we get that the limit goes to infinity, we get that the sequence diverges.
Sequence:
[tex]a_n = \frac{n^3 + 3n}{n^2 - 6n}[/tex]
Limit as n goes to infinity:
Limit of n going to infinity, so we consider just the terms with the highest exponent in the numerator and in the denominator.
[tex]\lim_{n \rightarrow \infty} a_n = \lim_{n \rightarrow \infty} \frac{n^3 + 3n}{n^2 - 6n} = \lim_{n \rightarrow \infty} \frac{n^3}{3n^2} = \lim_{n \rightarrow \infty} \frac{n}{3} = \frac{\infty}{3} = \infty[/tex]
Thus, the correct answer is that the sequence diverges.

C A L C U L A T I O N SWhat is the greatest common factor of 39, 42, and 33?
HELP PLSSS!!!
The greatest common factor (GCF) of 33 and 39 is 3. We will now calculate the prime factors of 33 and 39, then find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 33 and 39.
here you go
Answer: The greatest common factor of 39, 42, and 33 is 3
Step-by-step explanation:
We first find the factors of the numbers
39=1x39, 3x13 (1,3,13,39)
42=1x42, 2x21, 3x14, 6x7(1,2,3,6,7, 42)
33=1x33, 3x11(1,3,11.33)
The common factors are the factors that appear in the three numbers which are 1 and 3
The greatest common factor therefore is 3

Describe the end behavior of f(x)=-2x^3 using the leading coefficient and degree, and state the domain and range
Answer:
See explanation for end behavior below
Domain = All Real numbers
Range = All Real numbers
Step-by-step explanation:
This is a typical power function of order 3, and since its coefficient is a negative one (-2), its end behavior is:
As x becomes more and more negative (moving towards the left of the horizontal axis, the values for y will become larger and larger (reaching very positive numbers on the y scale). As x becomes larger and larger (moving towards large values on the positive side of the horizontal axis, the related y values will become more and more negative.
The Domain of the function (the x-values for which the function is defined) consists of all Real numbers.
The same is true for the Range, since the y-values spread over all the real number line.

difference from mean/14 is z-score
z<=-3 for a score of 28 (28-70)/14. This would be about 0.0013 or 0.13%
z<=-2 for a score of 42, and that is about 0.0228
z<=-1 for a score of 56 and +1 for a score of 84. That is about 68%
between 70 and 84 is a z-score between 0 and 1, and that is about 34%
Higher than 98 is greater than 2 standard deviations, and that is 2.28%

pleaseeeeeeee HELPPPPPPPPPPPp In a parking lot, 25% of the cars are SUVs, and 40% are pickup trucks. The rest of the cars are sedans. There are 21 sedans. How many cars are in the parking lot?
Answer:
60 cars
Step-by-step explanation:
In order to find how many total cars are in the parking lot, you must use a ratio. This is what you know:
25% = SUVs
40% = pickups
X% = cars
100% - (25% + 40%) = 35%. Thus, the remaining 35% of the cars are sedans. Now, we use a ratio to find the TOTAL number vehicles. See below:
X/65% * 21/35% = 35x = (21x65) = 1,365 (Hint: remember cross-multiplying??)
35x = 1,365
x = 1,365/35
x = 60 total cars
Sanity check:
25% of 60 = 15 SUVs
40% of 60 = 24 pickups
35% of 60 = 21 sedans
TOTAL: 60 cars
Answer:
60

What is the equation of the line with a y-intercept of 4 and a point (8,8)?
Answer:
The equation of the line with a y-intercept of 4 and a point (8,8) is [tex]y=\frac{1}{2} *x+4[/tex]
Step-by-step explanation:
A linear equation can be expressed in the form
y = m * x + b
where x and y are coordinates of a point, m is the slope and b is the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.
Graphically this equation represents a line.
In this case, you know:
The point (x,y)=(8,8)Y-intercept= 4Replacing:
8=m*8 +4
Solving:
8-4=m*8
4=m*8
4÷8= m
[tex]m=\frac{1}{2}[/tex]
Then, the equation of the line with a y-intercept of 4 and a point (8,8) is [tex]y=\frac{1}{2} *x+4[/tex]

Six numbers form an arithmetic sequence with a common difference of 4. The sum of these numbers equals to 12. What are the six numbers?
PLS ANSWER! ITS FINE IF YOU DONT SHOW WORK!
Answer:
-8, -4, 0, 4, 8, 12
Step-by-step explanation:
The nth term Tn of an arithmetic sequence with a common difference d and a first term a is given as
Tn = a + (n - 1) d
Hence if the first term is a and the common difference is d then
the
2nd term = a + 4
3rd term = a + (3 - 1) 4 = a + 8
4th term = a + (4 - 1) 4 = a + 12
5th term = a + (5 - 1) 4 = a + 16
6th term = a + (6 - 1) 4 = a + 20
If the sum of these six numbers is 12 then
a + a + 4 + a + 8 + a + 12 + a + 16 + a + 20 = 12
6a + 60 = 12
collect like terms
6a = 12 - 60
6a = -48
divide both sides by 6
a= -8
the numbers are
a = -8
2nd term = a + 4 = -8 + 4 = -4
3rd term = a + (3 - 1) 4 = a + 8 = -8 + 8 = 0
4th term = a + (4 - 1) 4 = a + 12 = -8 + 12 = 4
5th term = a + (5 - 1) 4 = a + 16 -8 + 16 = 8
6th term = a + (6 - 1) 4 = a + 20 = -8 + 20 = 12

Find the slope and intercept of the line with the equation 10x + 2y = 36.
Answers:
slope = -5
y intercept = 18
================================================
Work Shown:
Solve for y
10x+2y = 36
2(5x+y) = 36
5x+y = 36/2 .... dividing both sides by 2
5x+y = 18
y = 18-5x .... subtract 5x from both sides
y = -5x+18
The last equation is in slope intercept form y = mx+b.
We have m = -5 as the slope and b = 18 as the y intercept.
The slope -5 can be written as -5/1 to indicate "go down 5, go over to the right 1".

Missy is getting married and addressing invitations. She has at least 140 envelopes and has addressed 26 of them. Write an inequality that describes how many more invitations must be addressed.
Answer:
e ≥ 114 where e is the number of envelopes
Step-by-step explanation:
Let the number of envelopes for invitations to address be --------e
Hence the inequality of the number of envelopes is : e ≥ 140
Number of addressed envelopes is : 26
Remaining number of envelopes to address is : 140 -26 = 114 or more
The inequality that describes how many more invitations must be addressed is ;
e ≥ 114
