Which statement about the function is true?
O The function is increasing for all real values of x
where
x<-4.
Answer:
A.) The function is increasing for all real values of x where x < -4
Step-by-step explanation:
On the interval x < -4, all of the x values are increasing. Before x = -4, the line assumes a positive slope because it is heading upwards. After this interval, the function is decreasing because the slope is heading downwards.
On the interval -6 < x < -2, all of the x values are positive because they lie above the x-axis. This does not necessarily mean that all of the values are increasing.
On the interval x < -6 and x > -2, all of the x values are negative because they lie below the x-axis.

is an altitude in triangle wxz. if δywz ~ δyxw, what is true about xwz?
What is true about ΔXWZ is that the ratio of its altitude to the corresponding altitude in ΔYWZ is equal to the ratio of the length of XW to the length of YZ.
If ΔYWZ is similar to ΔYXW, it means that these two triangles have corresponding angles that are equal and corresponding sides that are proportional. In this case, we are specifically interested in the altitude of ΔWXZ, which we will denote as h.
Since ΔYWZ is similar to ΔYXW, we can establish the following proportion based on their corresponding sides:
YZ/YX = YW/YW
Let's denote the length of YZ as a and the length of YW as b. We can rewrite the proportion as:
a/YX = b/YW
Now, let's consider ΔXWZ. Since XW is common to both triangles, we can conclude that the altitude of ΔXWZ, which we will denote as k, is also proportional to the altitude of ΔYWZ (h). Therefore, we can express this proportion as:
k/h = XZ/YZ
To establish a relationship between k and h, we need to find a way to relate XZ to YZ. Using the proportion established earlier, we can substitute a for YZ:
k/h = XZ/a
To relate XZ to YZ, we need to find a relationship between XZ and YX. Again, using the similarity of the triangles, we have:
XZ/YZ = XW/YW
Substituting the value of YZ (a) from the earlier proportion, we have:
XZ/a = XW/YW
Now, we can combine the two proportions to find the relationship between k and h:
k/h = (XW/YW) * (YW/a)
Simplifying further, we get:
k/h = (XW/a)
From this equation, we can conclude that the ratio of the altitudes k/h in ΔXWZ and h in ΔYWZ is equal to the ratio of XW to YZ. In other words, the ratio of the altitudes is equal to the ratio of the corresponding sides in the similar triangles.

final price after tax =$48+2.88=$50.88
4. Chef finds that the children at Kennedy Elementary school drink 6 fl. oz. of milk with breakfast and 12 fl. oz. of milk for lunch. There are 212 students in grades 1 through 3 that eat the school lunch daily. 48 students come to breakfast. The kindergarten class has 8 fl. oz. of milk for snack time and they do not have breakfast or lunch. There are 38 kindergarten students. How many gallons of milk does Chef need daily?
Answer:
24.5 gallons of milk
Step-by-step explanation:
To calculate the total amount of milk needed daily, we need to find the total amount of milk consumed by all the students and convert it into gallons.
For grades 1 through 3, the total amount of milk consumed daily at lunch is:
12 fl. oz. x 212 students = 2,544 fl. oz.
For breakfast:
6 fl. oz. x 48 students = 288 fl. oz.
For kindergarten snack time:
8 fl. oz. x 38 students = 304 fl. oz.
Adding up all these amounts gives us the total amount of milk consumed daily:
2,544 fl. oz. + 288 fl. oz. + 304 fl. oz. = 3,136 fl. oz.
To convert this to gallons, we need to divide by 128 (the number of fluid ounces in a gallon):
3,136 fl. oz. ÷ 128 = 24.5 gallons (rounded to the nearest tenth)
Therefore, Chef needs approximately 24.5 gallons of milk daily to serve all the students.

a convention manager finds that she has $1320, made up of twenties and fifties. she has a total of 48 bills. how many fifty-dollar bills does the manager have?
The required manager has 12 fifty-dollar bills as of the given condition.
Let's denote the number of twenty-dollar bills as "x" and the number of fifty-dollar bills as "y".
We know that the convention manager has a total of 48 bills, so:
x + y = 48
We also know that the total amount of money she has is $1320, which can be expressed as:
20x + 50y = 1320
To solve for "y", we can rearrange the first equation to get:
y = 48 - x
Then substitute this expression for "y" in the second equation:
20x + 50(48 - x) = 1320
Expanding the expression and simplifying:
20x + 2400 - 50x = 1320
-30x = -1080
x = 36
So the manager has 36 twenty-dollar bills. To find the number of fifty-dollar bills, we can use the first equation:
x + y = 48
36 + y = 48
y = 12
Therefore, the manager has 12 fifty-dollar bills.

Step-by-step explanation:
You can divide both sides by 2.
Let A = PDP-1 And Compute A4. P = [1 2 2 3], D = [1 0 0 3]
A4 = [1 32/27 32/27 81]. To compute A4, we first need to find A. From the given equation A = PDP-1, we can substitute the values of P and D to get:
A = [1 2 2 3] [1 0 0 3]^-1
To find the inverse of D, we can simply take the reciprocal of each non-zero element on the main diagonal. In this case, the inverse of D is:
D^-1 = [1 0 0 1/3]
Substituting this value into the equation for A, we get:
A = [1 2 2 3] [1 0 0 1/3]
= [1 2/3 2/3 3]
Now that we have A, we can easily compute A4 by raising A to the fourth power. That is:
A4 = A x A x A x A
= [1 2/3 2/3 3] x [1 2/3 2/3 3] x [1 2/3 2/3 3] x [1 2/3 2/3 3]
= [1 32/27 32/27 81]

Two angles whose sum in 90 degrees
Step-by-step explanation:
Jamel plans to take a cruise that leaves out of New Orleans and needs to rent a car to see the sights as well as travel to and from the airport. The cost of renting a car is $50 plus $0.75 per mile for every mile over 40 miles driven. If Jamel's total cost for renting the car is $122.75, use the composition of functions to find how many miles Jamel drove the car on his vacation?
The number of miles that Jamel drove the car on his vacation was 97 miles.
Let the number of miles that he traveled be represented by x.
Based in the information given, the equation to solve the question will be:
50 + (0.75 × x) = 122.75
50 + 0.75x = 122.75
Collect like terms
0.75x = 122.75 - 50
0.75x = 72.75
Divide both side by 0.75
0.75x/0.75 = 72.75/0.75
x = 97
Therefore, Jamel drove the car for 97 miles.

There are several different sampling methods that could be employed for this study, including:
Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.
Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.
Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.
Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.
This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.
It is not an analytic study because it doesn't involve testing a hypothesis or making causal inferences.

Step-by-step explanation:
2\(\sqrt{5}\)= 2.23606798

-------
4.47213596
4.47213596^2 + 4.47213596^2 = 8.94427192^2

A fair coin is tossed 5 times. Calculate the probability that (a) five heads are obtained (b) four heads are obtained (c) one head is obtained A fair die is thrown eight times. Calculate the probability that (a) a 6 occurs six times (b) a 6 never happens (c) an odd number of 6s is thrown.
To calculate the probabilities, we need to use the concept of binomial probability.
For a fair coin being tossed 5 times:
(a) Probability of getting five heads:
The probability of getting a head in a single toss is 1/2.
Since each toss is independent, we multiply the probabilities together.
P(Head) = 1/2
P(Tails) = 1/2
P(Five Heads) = P(Head) * P(Head) * P(Head) * P(Head) * P(Head) = \((1/2)^5\) = 1/32 ≈ 0.03125
So, the probability of obtaining five heads is approximately 0.03125 or 3.125%.
(b) Probability of getting four heads:
There are five possible positions for the four heads.
P(Four Heads) = (5C4) * P(Head) * P(Head) * P(Head) * P(Head) * P(Tails) = 5 * \((1/2)^4\) * (1/2) = 5/32 ≈ 0.15625
So, the probability of obtaining four heads is approximately 0.15625 or 15.625%.
(c) Probability of getting one head:
There are five possible positions for the one head.
P(One Head) = (5C1) * P(Head) * P(Tails) * P(Tails) * P(Tails) * P(Tails) = 5 * (1/2) * \((1/2)^4\) = 5/32 ≈ 0.15625
So, the probability of obtaining one head is approximately 0.15625 or 15.625%.
For a fair die being thrown eight times:
(a) Probability of a 6 occurring six times:
The probability of rolling a 6 on a fair die is 1/6.
Since each roll is independent, we multiply the probabilities together.
P(6) = 1/6
P(Not 6) = 1 - P(6) = 5/6
P(Six 6s) = P(6) * P(6) * P(6) * P(6) * P(6) * P(6) * P(Not 6) * P(Not 6) = \((1/6)^6 * (5/6)^2\) ≈ 0.000021433
So, the probability of rolling a 6 six times is approximately 0.000021433 or 0.0021433%.
(b) Probability of a 6 never happening:
P(No 6) = P(Not 6) * P(Not 6) * P(Not 6) * P(Not 6) * P(Not 6) * P(Not 6) * P(Not 6) * P(Not 6) = \((5/6)^8\) ≈ 0.23256
So, the probability of not rolling a 6 at all is approximately 0.23256 or 23.256%.
(c) Probability of an odd number of 6s:
To have an odd number of 6s, we can either have 1, 3, 5, or 7 6s.
P(Odd 6s) = P(One 6) + P(Three 6s) + P(Five 6s) + P(Seven 6s)
\(P(One 6) = (8C1) * P(6) * P(Not 6)^7 = 8 * (1/6) * (5/6)^7P(Three 6s) = (8C3) * P(6)^3 * P(Not 6)^5 = 56 * (1/6)^3 * (5/6)^5P(Five 6s) = (8C5) * P(6)^5 * P(Not 6)^3 = 56 * (1/6)^5 * (5/6)^3P(Seven 6s) = (8C7) * P(6)^7 * P(Not 6) = 8 * (1/6)^7 * (5/6)\)
P(Odd 6s) = P(One 6) + P(Three 6s) + P(Five 6s) + P(Seven 6s)
Calculate each term and sum them up to find the final probability.
After performing the calculations, we find that P(Odd 6s) is approximately 0.28806 or 28.806%.

a rectangle's length is 5cm more than its width, if it has an area of 336 cm squared find the length
The length of the rectangle is 19 cm.
The formula for the area of a rectangle,
Area = Length x Width
Given that the area is 336 cm squared.
So, we can set up an equation,
⇒ 336 = (w + 5)w
where w represents the width of the rectangle.
Expanding this equation,
⇒ 336 = w² + 5w
Moving all terms to one side:
⇒ w² + 5w - 336 = 0
This is a quadratic equation that we can solve using the quadratic formula,
⇒ w = (-5 ± √(5² - 4(1)(-336))) / (2(1))
⇒ w = (-5 ± 23) / 2
We'll take the positive value,
⇒ w = 14
So, the width of the rectangle is 14 cm.
We also know that the length is 5 cm more than the width,
Therefore,
⇒ l = w + 5
⇒ l = 14 + 5
⇒ l = 19
Therefore, the length of the rectangle is 19 cm.
