Which function has an inverse that is a function?
b(x) = x2 + 3
d(x) = –9
m(x) = –7x
p(x) = |x|
Answer:
All but the second one
Step-by-step explanation:
Find the inverse of each function:
b(x)=x^2+3
y=x^2+3
x=y^2+3
x-3=y^2
sqrt(x-3)=y
This inverse function is a function
d(x)=-9
y=-9
This doesn't have an inverse function
m(x)=-7x
y=-7x
x=-7y
-1/7x=y
This inverse function is a function
p(x)=|x|
y=|x|
x=|y|
x=y
This inverse function is a function
Therefore, all but the second function have inverses that are functions
Answer:
All but the second one have inverse functions

i need help can yall help
Answer:
ummm yes what the problem?
34% of 65. Do not round!!! pls help
Answer:
22.1
Step-by-step explanation:
If we put 65 over 100 and x over 34 and do cross multiplication, we see that 65 times 34 is 2,210. Dividing 100 from both sides of the equation, we divide 100 from x and 100 from 2,210. We are left with X = 22.1

Mike and Charlie are facing each other. There is a flagpole exactly halfway between them. Their line of sight to the top of the flagpole is 16 feet, with an angle of elevation of 60°.
Mike and Charlie both calculated the height of the flagpole as shown below.
Mike's Calculation Charlie's Calculation
Examine Mike and Charlie's calculations and complete the statement below.
The person with the incorrect reasoning for the height of the flagpole is
, because he incorrectly selected the
function, when he should have utilized the
function.
Answer:
Charlie is incoerre
Step-by-step explanation:
Given that :
Line of sight to top of flagpole = 16 feets
Angle of elevation = 60°
The height of the flagpole :
Applying trigonometry to the drawing in the attached picture :
We use:
Sinα = opposite / hypotenus
This enables us to use the value of the hypotenus (line of sight) to obtain the missing height value (h)
Sin(60°) = h / 16
h = 16 * sin 60
h = 16 * 0.8660254
h = 13.856406
Hence flagpole is about 13.86 feets high
Charlie's reasoning is incorrect, the line of sight constitutes the hypotenus and not Adjacent and hence, shoul
filling in missing values!

The data are skewed right, so most students' practice times are
less than the mean practice time.
Answer:
a. The data are skewed left, so most student's practice times are more than the mean practice time.
b. The data are skewed left, so most student's practice times are less than the mean practice time.
c. The data are skewed right, so most student's practice times are less than the mean practice time.
d. The data are skewed right, so most student's practice times are more than the mean practice time.
Answer:
The correct option is a.
The data are skewed left, so most student's practice times are more than the mean practice time.
Step-by-step explanation:
Refer to the attached box plot which shows number of hours the students spent on practice for playing their instrument each week.
When the data distribution is not symmetric around the mean then it is either skewed to right or skewed to left.
The given box plot is skewed to the left since the tail of the distribution on the left side is longer than the right side or in other words, most of the data is leaning to the right side of the curve.
Due to this, most student's practice times are more than the mean practice time.
A left skewed distribution is also known as negatively skewed distribution.
Therefore, we can conclude that the correct option is a.
a. The data are skewed left, so most student's practice times are more than the mean practice time.

A water tank fills through two pipes. Water flows in
through one pipe at a rate of 25,000 gallons per hour
and in through the other pipe at a rate of 45,000
gallons per hour. Water leaves the system at a rate of
60,000 gallons per hour.
There are 3 of these tanks, and each tank holds
1 million gallons. Each tank is half full. Water is

what is 699.03 to the nearest penny?
need this ASAP thanks
Answer:
699.03??
Step-by-step explanation:
The penny value only falls as low as the hundredths place meaning two 0's behind the decimal point. If you have a total of $699.03 than there are no corrections to be made. I'm only in Algebra I so im not entirely sure if PENNY is a phrase for a certain mathematical operation so i'm not entirely sure.
The scatter plot shows the relationship between years of experience and hourly pay at one factory.
describe the relationship between experience and pay years of work
Answer:
I'm pretty sure it's B.
Step-by-step explanation:
The more experience you have, the better you are at your job. If your doing better at your job, you get better pay.
Good luck on the test BTW. =)
The correct answer is option B which is the hourly pay usually increases with the work experience.
What is a scatter plot?Scatter plots are graphs that show how two variables in a data collection relate to one another. On a two-dimensional plane or in a Cartesian system, it represents data points.
In the given graph horizontal axis contains the years of experience and the vertical axis consists of the hourly pay of an employee. We can see that the employees with higher experience are paid a higher hourly amount.
Therefore the correct answer is option B which is the hourly pay usually increases with the work experience.

If you have a decimal answer, round to the nearest tenth!
8n−6=2n+13
Answer:
n = 3.17
Step-by-step explanation:
Given:
8n − 6 = 2n + 13
Collect like terms
8n - 2n = 13 + 6
6n = 19
Divide both sides by 6
n = 19/6
= 3.167
Approximately to the nearest tenth
n = 3.17
