If the graph f(x)= 9x^2+36x+41/3x+5 has an oblique asymptote at y=3x+k what is the value of k
Answers
Answer:
The value of k is 7.Explanation:
To find the oblique asymptote of a rational function you divide the numerator by the denominator and take the quotient (not the remainder).
Such quotient (without the remainder) is the equation of the line that is the oblique asymptote of the rational function.
The rational function is:
[tex]\frac{9x^2+36x+41}{3x+5}[/tex]
You can see the long division in the picture attached. The quotient is 3x + 7.
Hence, by comparison with y = 3x + k, k = 7.

Determine whether the quantitative variable is discrete or continuous. Depth of the ocean floor Is the variable discrete or continuous? A. The variable is discrete because it is countable. B. The variable is continuous because it is not countable. C. The variable is discrete because it is not countable. D. The variable is continuous because it is countable.
Answers
Answer:
B. The variable is continuous because it is not countable.
Correct, from the definition about of continuous data we see that is a random variable is continuous then it can't be countable.
Step-by-step explanation:
Previous concepts
A discrete random variable "has a countable number of possible values" in a domain defined. So then the possible values for these types of random variables are the integers.
A continuous is a random variable "where the data can take infinitely many values" that means that can take values from the rational with decimals. Ans is not countable.
Solution to the problem
Let's analyze one by one the possible options:
A. The variable is discrete because it is countable.
False, the depth of the ocean is a continuous random variable since we can have for exampe a depth of 1200.56 mi and we can't express this as a discrete random variable.
B. The variable is continuous because it is not countable.
Correct, from the definition about of continuous data we see that is a random variable is continuous then it can't be countable.
C. The variable is discrete because it is not countable.
False, the depth of the ocean is a continuous random variable since we can have for exampe a depth of 504.67 Km and we can't express this as a discrete random variable.
D. The variable is continuous because it is countable.
False the variable is continuous but cannot be countable since that's the opposite from the definition of continuous random variable.
The correct answer is option is B). The variable is continuous because it is not countable.
The depth of the ocean floor is a quantitative variable that can take on any value within a range and can be measured to any level of precision. This means that the depth can be a non-integer number and is not restricted to integer counts. Therefore, it is not countable in the sense that one can count individual, distinct units, such as the number of people in a room or the number of cars in a parking lot. Instead, the depth of the ocean floor is a continuous variable because it can vary smoothly and without gaps over a range of values.
To illustrate, consider that the depth of the ocean can be 100.5 meters, 100.52 meters, 100.526 meters, and so on, with an infinite number of possible values between any two depths. This characteristic of having an infinite number of possible values within any given interval is what defines a continuous variable.
Four houses in a row are each to be painted with one of the colors red, blue, green, and yellow. In how many different ways can the houses be painted so that no two adjacent houses are of the same color? There are possible ways to paint the houses.
Answers
Answer:
Possible ways to paint the house is 108
Step-by-step explanation:
Total number of houses to be painted=4
Total number of colours to b used(red,blue,green and yellow)=4
Number of ways to paint the first house=4
Number of ways to paint the second house=3
Number of ways to paint the third house=3
Number of ways to paint the fourth house=3
Total number of ways to paint the 4 houses=4×3^3=108 ways.
Final answer:
There are 24 different ways to paint the houses so that no two adjacent houses are of the same color.
Explanation:
To solve this problem, we can use the concept of permutations. Since there are 4 houses and 4 colors to choose from, we can start by selecting a color for the first house. We have 4 options for the first house. Next, we need to choose a color for the second house, but we must ensure that it is different from the color chosen for the first house. We have 3 options for the second house. For the third house, we have 2 options, and for the fourth house, we have only 1 option.
Therefore, the total number of ways to paint the houses without any two adjacent houses being the same color is calculated as:
4 x 3 x 2 x 1 = 24

There are 13 steps in the stairwell, each measuring one foot by three foot. In order to cover all the steps, how many square feet of carpet does Mr. Meglio need to purchase?
Answers
Answer:
Mr. Meglio need to purchase 39 square feet of carpet.
Step-by-step explanation:
Given:
Total number of steps = 13
Length of each step = 1 foot
Width of each step = 3 foot
We need to find the square feet of carpet does Mr. Meglio need to purchase.
Solution:
First we will find the area of each step.
area of each step is equal to length times width.
framing in equation form we get;
area of each step = [tex]1\times 3 = 3\ ft^2[/tex]
Now amount of carpet required in square feet we multiply number of step with area of each step.
framing in equation form we get;
Amount of carpet required = [tex]13\times3 =39\ ft^2[/tex]
Hence Mr. Meglio need to purchase 39 square feet of carpet.
Final answer:
Mr. Meglio needs to purchase 39 square feet of carpet to cover the 13 steps in the stairwell, as each step has an area of 3 square feet.
Explanation:
The student is asking how many square feet of carpet are needed to cover a stairwell with 13 steps, where each step is one foot by three feet.
To calculate the area of a single step, multiply the length by the width. For one step, the calculation is 1 foot × 3 feet = 3 square feet. Since there are 13 steps, multiply the area of one step by the number of steps: 3 square feet/step × 13 steps = 39 square feet. Therefore, Mr. Meglio will need to purchase 39 square feet of carpet to cover all the steps.
This type of problem is a practical application of the area calculation in real-world context, and the measurement conversion from square inches to square feet is also pertinent to understanding the measurement of areas in different units.

In a school one-third of all 240 students play soccer. Forty four students play both soccer and basketball and sixty students do not play any of these games. How many students play only basketball?
Answers
Answer:
100 students play only basketball.
Step-by-step explanation:
We are given the following information in the question:
Total number of students in school = 240
Number of students that play soccer =
[tex]\dfrac{1}{3}\times \text{Total number of students}\\\\=\dfrac{1}{3}\times 240 = 80[/tex]
n(S) =80
[tex]n(S\cap B) = 44[/tex]
[tex]n(S'\cap B') = 60[/tex]
Formula:
[tex]n(S\cup B) = \text{Total} - n(S' \cap B')\\n(S\cup B) = n(S) + n(B) - n(S\cap B)[/tex]
Putting the values, we get,
[tex]n(S\cup B) =240-60=180\\n(S\cup B) = 180 = 80 - 44 + n(B)\\n(B) = 180 - 80 + 44= 144[/tex]
Thus, 144 students play basketball.
Out of these 144, 44 plays soccer as well.
[tex]\text{Student only playing basketball} = 144 -44 = 100[/tex]
Thus, 100 students play only basketball and not soccer.

A 40 question test has 132 possible points there are M 5 point questions. And N 1 point questions how many of each type of questions is on the test?
Answers
Answer:
There are 23 5-point questions and 17 1-point questions.
Step-by-step explanation:
there are M 5 point questions
And N 1 point questions
M + N = 40
A 40 question test has 132 possible points
5M + N = 132
We have a system of equations.
M + N = 40
5M + N = 132
Multiply both sides of the first equation by -1. Write the second equation below it. Add the equations.
-M - N = -40
+ 5M + N = 132
----------------------------
4M = 92
M = 23
Now substitute 23 for M in the first equation and solve for N.
M + N = 40
23 + N = 40
N = 17
There are 23 5-point questions and 17 1-point questions.
Answer:the number of 5 point questions is 23
the number of 1 point questions is 17
Step-by-step explanation:
Let M represent the number of 5 point questions.
Let N represent the number of 1 point questions.
The total number of questions in the test is 40. It means that
M + N = 40 - - - - - - - - - - - - 1
The possible total points in the test is 132 and it contains M 5 point questions and N 1 point questions. This means that
5M + N = 132 - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- 4M = - 92
M = - 92/-4 = 23
Substituting M = 23 into equation 1, it becomes
23 + N = 40
N = 40 - 23 = 17
The marching band in selling poinsettias and wreaths to raise money for new uniforms. Trey sold 7 poinsettias and 3 wreaths and raised $201. Molly sold 4 poinsettias and 6 wreaths and raised $252. How much is a poinsettia
Answers
The cost of 1 poinsettia is $ 15
Solution:
Let "x" be the cost of 1 poinsettias
Let "y" be the cost of 1 wreath
Trey sold 7 poinsettias and 3 wreaths and raised $201
Therefore, we frame a equation as:
7 poinsettias x cost of 1 poinsettias + 3 wreaths x cost of 1 wreath = 201
[tex]7 \times x + 3 \times y = 201[/tex]
7x + 3y = 201 ------- eqn 1
Molly sold 4 poinsettias and 6 wreaths and raised $252
4 poinsettias x cost of 1 poinsettias + 6 wreaths x cost of 1 wreath = 252
[tex]4 \times x + 6 \times y = 252[/tex]
4x + 6y = 252 ------- eqn 2
Multiply eqn 1 by 2
14x + 6y = 402 -------- eqn 3
Subtract eqn 2 from eqn 3
14x + 6y = 402
4x + 6y = 252
( - ) -----------------------
10x = 150
x = 15
Thus cost of 1 poinsettia is $ 15
The price of a poinsettia is $15.
To determine the price of a poinsettia, we need to set up and solve a system of linear equations based on the given information.
Trey sold 7 poinsettias and 3 wreaths and raised $201. Let's denote the price of a poinsettia as 'P' and the price of a wreath as 'W'. Thus, the equation is:7P + 3W = 201
Molly sold 4 poinsettias and 6 wreaths and raised $252. Therefore, the equation is:4P + 6W = 252
To eliminate one variable, we can multiply the first equation by 2 to get:14P + 6W = 402Now, subtract the second equation from the new equation:(14P + 6W) - (4P + 6W) = 402 - 25210P = 150P = 15Therefore, the price of a poinsettia is $15.

Grace started her own landscaping business. She charges $6 an hour for mowing lawns and $11 per house pulling weeds. In September she mowed lawns for 63 hours and pulled weeds for 9 hours. How much money did she make in September?
Answers
Answer:
The total money made by Grace is $477.
Step-by-step explanation:
Given:
Charge per hour for mowing lawn = $6
Charge per hour for pulling weeds = $11
Number of hours for which lawns are mowed = 63 hours
Number of hours for which weeds are pulled = 9 hours
Now, total money made by Grace in September can be calculated by adding the total money gained in mowing lawns and pulling weeds.
Total money gained in mowing lawns is given as:
[tex]C_m=\textrm{Number of hours of mowing}\times\textrm{Charge per hour}\\\\C_m=63\times 6=\$378[/tex]
Total money gained in pulling weeds is given as:
[tex]C_w=\textrm{Number of hours of pulling weeds}\times\textrm{Charge per hour}\\\\C_w=9\times 11=\$99[/tex]
Now, total money made = [tex]C_m+C_w=378+99=\$477[/tex]
Therefore, the total money made by Grace is $477.
