Answer:
[tex]\mathrm{Inverse\:of}\:-n+2:\quad 2-n[/tex]
Step-by-step explanation:
Given the function
[tex]\:g\left(n\right)\:=-n\:+\:2[/tex]
As we know that a function g is the inverse of function if for [tex]y=f\left(x\right),\:\:x=g\left(y\right)\:[/tex]
[tex]y=-n+2[/tex]
Replace n with y
[tex]n=-y+2[/tex]
Solve for y,
[tex]n=-y+2[/tex]
[tex]y=2-n[/tex]
Therefore,
[tex]\mathrm{Inverse\:of}\:-n+2:\quad 2-n[/tex]

Sorry this is super messy, Hope it makes sense! Tell me if it doesn't :)
Help asap please!! Will give brainliest!!
Answer:
5 units
Step-by-step explanation:
The points are:
[tex]A(-2, 5)[/tex]
[tex]B(-2, -7)[/tex]
[tex]C(-6, -4)[/tex]
Considering the sides as vectors, we have:
[tex]\overrightarrow{AB}, \overrightarrow{AC},\overrightarrow{CB}[/tex]
Once
[tex]\overrightarrow{AC} = C - A =(-6, -4) -(-2, 5) = (-6+2, -4-5) = (-4, -9)[/tex]
[tex]\overrightarrow{AB} = B - A =(-2, -7) -(-2, 5) = (-2+2, -7-5) = (0, -12)[/tex]
[tex]\overrightarrow{CB} = B - C =(-2, -7) -(-6, -4) = (-2+6, -7+4) = (4, -3)[/tex]
[tex]\Vert \overrightarrow{AC} \Vert = \sqrt{x^2 + y^2} = \sqrt{(-4)^2+(-9)^2} = \sqrt{16+81}= \sqrt{97}[/tex]
[tex]\Vert \overrightarrow{AB} \Vert = \sqrt{x^2 + y^2} = \sqrt{0^2+(-12)^2} = \sqrt{144}= 12[/tex]
[tex]\Vert \overrightarrow{CB} \Vert = \sqrt{x^2 + y^2} = \sqrt{4^2+(-3)^2} = \sqrt{16+9}= 5[/tex]

David loves to cook! He knew 21 recipes before starting cooking school and he learns 2 recipes
every 1 one week. An equation to represent that is y = 21 + 2x where x represents number of
weeks and y represents number of recipes.
His friend Sarah believes that if he attends school for 10 weeks that means he knows 42 recipes.
Explain if she is correct.
Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is not 42 - it's 41. So, Sarah is incorrect.
Answer:
Sarah is not correct because if David already knows 21 recipes and learns 2 recipes per week, then he will know only 41 recipes after 10 weeks, not 42.
Step-by-step explanation:
To see if Sarah is correct, let's replace the y in the equation with 42 and the x with 10:
y = 2x + 21
42 = 2(10) + 21
42 = 20 + 21
42 [tex]\neq[/tex] 41
Sarah is wrong.

A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
[tex]Volume = 18312.48[/tex]
Step-by-step explanation:
Given
[tex]Height (h) = 18mm[/tex]
[tex]Radius (r) = 18mm[/tex]
Required
Determine the volume
The volume of a cylinder is calculated as thus:
[tex]Volume = \pi r^2h[/tex]
Substitute values for r and h
[tex]Volume = 3.14 * 18^2 * 18[/tex]
[tex]Volume = 18312.48[/tex]
Hence, the volume of the cylinder is 18312.48mm³
find the domain of (5y-8)/11
The domain of the function f(y) = (5y - 8)/11 is the set of all real numbers.
Dom(f(y)) = R.
What is the domain and range of a function?Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
Given a function f(y) = (5y - 8)/11.
It is a real function and the domain of the function is the set of all real numbers.
There are no restrictions as the denominator is constant and no such values of 'y' make the denominator zero.

A study compared the number of years of education a person received and that person's yearly salary. It was determined that the relationship between these two quantities was linear and the correlation coefficient was 0.91. Which conclusion can be made based on the findings of this study?
Answer:
Salary earned increases as the number of years of education earned increases.
Step-by-step explanation:
Given that the correlation between the number of years of education a person receive and his yearly salary yields a linear relationship with a correlation Coefficient of 0.91, this shows that a strong positive relationship exists between the two measured quantities, this is deduced by the positive nature of the correlation Coefficient value obtained and the fact that the value of the Coefficient is close to 1. Hence, salary earned increases as the number of years of education increases and Vice versa.

What is the equivalent form of the mathematical expression 14 + 35?
Group of answer choices
2(7 + 17)
14(1 + 21)
7(2 + 5)
10(4 + 15)
Answer:
7(2 +5)
Step-by-step explanation:
Both the numbers (14 and 35) have a GCF (greatest common factor) of 7. If you divide both numbers by 7, you get 2 and 5. Therefore, your answer would be 7(2 +5)
Answer:
I guess it is A because it is the closest to the answer for the expression 14 + 35.

Find the unknown angle measured
Answer:
b=121, a and c=59
Step-by-step explanation:
b and 121 are congruent angles, so they are equal to each other.
each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.
a and c are congruent angles so they are also equal to each other
