characteristics of the functions? Select two options.
Of(x) has an all negative domain.
g(x) has the greatest maximum value.
All three functions share the same range.
Oh(x) has a range of all negative numbers.
All three functions share the same domain.
Answers
Answer:
The statements that can be used to compare the characteristics of the functions are:
1. g(x) has the greatest maximum value.
2. All three functions share the same domain.
Explanation:
- The table shows the values of three functions - f(x), g(x), and h(x) - evaluated at different values of x.
- We cannot determine the domain of f(x) or h(x) from the given table but we can see that g(x) has a domain of all real numbers.
- We can see that g(x) has the highest maximum value among the three functions, which is 8.
- We cannot determine the range of f(x) or g(x) from the given table but we can see that h(x) has a range of all negative numbers.
- We cannot say anything about the domain or range of f(x) based on the given table.
- Therefore, the two statements that can be used to compare the characteristics of the functions are: g(x) has the greatest maximum value and all three functions share the same domain.

Answers
Answer:
The perimeter is 19.7
Step-by-step explanation:
The question is not complete and there is no attachment. Nevertheless, we can make do with the given information.
we can picture that the shape is a circle and we are required to find the perimeter/circumference of the circular shape
Given
The radius r= 3.142
Step two:
the perimeter/circumference is expressed as

If 1300 square centimeters of material is available to make a box with a square base and an open top, find the largest possible
volume of the box.(include units)
Answers
it's useful to know that the box with the largest volume - to - surface area ratio is a cube. Your shape will be a cube (with a missing top).
Thus there will be five square faces with a total area of 1300 square centimeters. The area of each side will thus be:
1300/5 = 260
The length of each side will again be an irrational number (√260), because 260 is not a perfect square. This comes out to roughly:
16
The simplest way to do it from here would be to simply take the cube of your side length:
163 = 4096
Your box's volume will be roughly 4096 cm^3
Select all the ordered pairs that correspond to input-output pairs for the function y= -2x+3.
Answers
3 Answers: Choice B, Choice C, Choice D
In other words, only choice A is false.
===================================================
Explanation:
Each ordered pair is of the form (x, y) where x goes first.
For something like (2,7), we have x = 2 and y = 7 pair up.
Plug each into the equation and simplify both sides
y = -2x+3
7 = -2(2) + 3
7 = -4 + 3
7 = -1
We don't get the same thing on both sides, so (2,7) is not on this function curve. Instead, it should be (2, -1).
Therefore, we can rule out choice A
-----------------------
Let's try choice B. We have x = -2 and y = 7 this time
y = -2x+3
7 = -2(-2) + 3
7 = 4 + 3
7 = 7
We get the same thing on both sides, so (-2,7) is on the line y = -2x+3
You should find that choices C and D are also on the line through similar steps.

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 120 and standard deviation of 16 .
Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher.
a. Around what percentage of adults in the USA have stage 2 high blood pressure? Give your answer rounded to two decimal places.
Answers
Using the normal distribution, it is found that around 0.62% of adults in the USA have stage 2 high blood pressure.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
\(\mu = 120, \sigma = 16\).
The proportion with a stage 2 high blood pressure is one subtracted by the p-value of Z when X = 160, hence:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{160 - 120}{16}\)
Z = 2.5
Z = 2.5 has a p-value of 0.9938.
1 - 0.9938 = 0.0062.
0.0062 = 0.62% of adults in the USA have stage 2 high blood pressure.

A study followed for 10 years a sample of 82,695 middle-aged men with no prior history of heart failure living in California. The daily number of minutes spent being sedentary (seated) was recorded in diaries and reported on regularly administered questionnaires. During the course of the study, a total of 3,473 men experienced heart failures. Participants with high sedentary time and low sedentary times were compared. The proportion experiencing a heart failure was higher in the group of men spending more time being sedentary.
This study is an example of:_________
a. longitudinal cohort study
b. case-control observational study
c. voluntary response sample or anecdotal data
d. completely randomized experiment
e. matched pairs / repeated measures experiment
f. cross-sectional sample survey
g. census (population data)
Answers
Answer:
f. cross-sectional sample survey
Step-by-step explanation:
- longitudinal cohort study is when the group of subjects that comprises the cohort is chosen based on a disease or injury and is then monitored over time at routine intervals. In this question, it's not the case as the sample of men were just picked and studied with no special group or cohort.
- If it was case-control observational study, the research would have started with identifying those who have heart failure and those who don't have heart failure but it wasn't the case and thus this is not correct.
- If this was voluntary response sample, it means the men would have been self chosen which means they volunteered to be part of the study if it was of interest to them. But this is not the case here.
- If it was completely randomized experiment, it means that the people sampled would have been randomly assigned to different treatments which was not so in this question.
- If it were to be match pairs experiment, it means the men sampled would be grouped into pairs and each pair will be assigned different treatments which didn't happen in this question.
- If it were to be cross-sectional sample survey, it means that data will be collected from a population of interest to make inferences from that population at a point in time. That is the case here because data about sedentary time or less was taken and compared to know the effect it had on heart failure.
- If it were census, it will just be about getting the size of the population without making inquiries about sedentary time.
Suppose that the function f is defined on the interval (-2, 2) as follows.-2 if – 2
Answers
Given the function f which is defined as follows:
\(f(x)=\begin{cases}-2,-2\le x<-1 \\ -1,-1\le x<0 \\ 0,0\le x<1 \\ 1,1\le x<2 \\ \end{cases}\)To find the value of the function at a certain point of x, the value of x must satisfy the corresponding inequality
To find f(-2):
-2 lies in the first interval, f(-2) = -2
f(-0.5)
x = - 0.5 lies in the second interval, f(-0.5) = -1
f(1)
x = 1 lies in the fourth interval , f(1) = 1

For the following vectors, (a) find the dot product v•w ; (b) find the angle between v and w , (c) state whether the vectors are parallel, octagonal, or neither. V=-3i-4j, w=6i+8j
A- v•w
B-the angle between v and w is theta ^•?
C- the vectors v and w are?
Answers
B) The angle between vectors v and w can be found using the formula: cos(theta) = (v • w) / (||v|| ||w||), where ||v|| and ||w|| are the magnitudes of vectors v and w respectively.
First, we need to find ||v|| and ||w||:
||v|| = sqrt((-3)^2 + (-4)^2) = 5
||w|| = sqrt((6)^2 + (8)^2) = 10
Now, we can substitute in the values to get:
cos(theta) = (-50) / (5 * 10) = -1
theta = arccos(-1) = pi radians or 180 degrees.
Therefore, the angle between vectors v and w is 180 degrees.
C) Two vectors are parallel if their directions are the same, which can be determined by comparing their unit vectors.
The unit vector of v is:
v_hat = v / ||v|| = (-3/5)i + (-4/5)j
The unit vector of w is:
w_hat = w / ||w|| = (6/10)i + (8/10)j = (3/5)i + (4/5)j
We can see that the unit vectors are in opposite directions, which means that the vectors are anti-parallel or opposite. Therefore, the vectors v and w are neither parallel nor orthogonal.
Suppose $72 was budgeted for day trips. What would be the total amount budgeted for entertainment?
Answers
Using proportions, it is found that the total amount budgeted for entertainment is of $720.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching the problem on the internet, it is found that the day trip amount is 10% of the budget for entertainment, hence:
0.1x = 72
x = 72/0.1
x = 720.
Hence the total amount budgeted for entertainment is of $720.

*PART B:* Find the area of the vertical cross section of the cone. Explain how you arrived at your answer
Answers
Part A: Draw the cone's vertical cross section it through center.
PART B: The area of the cone's vertical cross section:7.875 sq. in.
Explain about the cone?In maths, a cone is defined as a distinctive three-dimensional geometric figure with a flat and curved surface pointed towards the top. The term “cone” is derived from the Greek word “konos”, which means a wedge or a peak. The pointed end is the apex, whereas the flat surface is called the base.
Given data:
Height of cone H = 6 in.
Diameter D / Base B = 2 ⁵/₈ in. = 21/8 in.
Part A: Draw the cone's vertical cross section it through center, noting the height H and base B of the cone. Slant height of cone is L.
The diagram is attached.
PART B: The area of the cone's vertical cross section.
cone's vertical cross section is in the form of triangle with base B equals to diameter of the cone and height is H.
Area = 1/2* base * height
Area = (1/2) * (21/8) * 6
Area = 7.875 sq. in.
Thus, the area of the cone's vertical cross section: 7.875 sq. in.
