f: M ⇒ N is a function from M to N.
Given,
f: M ⇒ N
We need to describe this mathematical statement in our own words.
What is a function?A function is defined as a way where there is an input that it takes and produces an output.
The set from where the inputs come is called the Domain.
The set of outputs is called the Range.
We have,
f: M ⇒ N
Here
f is a function that takes input from the set M and its output belongs to set N( Natural number).
Here,
M is called the domain.
N is called the codomain.
Thus f: M ⇒ N is a function from M to N.

Find the median and mode of 14 ,25, 14, 28, 18, 17, 18, 14, 23 22, 14 and 18
Answers
Answer:
Ascending order - 14, 14, 14, 14, 17, 18, 18, 22,
23, 25, 28
Median = ( n+1/2)
= ( 11+1/2)
= 12/2 = 6th term
Here, in order 6th term is 18, so 18 is median.
Mode is frequently occurring number.
Here frequently occurring number is 14 i,e 4 times.
Hence, 14 is mode.
Answer:
mode ; 14
median; 18
Step-by-step explanation:
Ans; 14, 14 , 14 ,14, 17 , 18 , 18 , 18 ,22, 23 , 25 , 28
mode ; 14
[tex]median = \frac{n}{2} = \frac{18 + 18}{2} = \frac{36}{2} \\ \\ median = 18[/tex]

The total bill (parts and labor) for the repair of a car was $458. The cost of parts was $339. The cost of labor was $34 per hour. How many hours of labor did it take to fix the car?
Answers
Answer:
3.5 Hours MARK ME AS BRAINLIEST PLEASE
Step-by-step explanation:
Take 458, and subtract 339 from it. Then, divide that by 34.
Answer:
3 and a half hours
Step-by-step explanation:
Subtract 399 from both sides
119 = 34h
Divide both sides by 34
3.5 = h

1+sin^4-cos^4a/1-sin^6-cos^6a=2/3cos^2a
Answers
Answer:
Step-by-step explanation:
From what I can come up with with no actual factual information is that the equation is
[tex]\frac{1+sin^4x-cos^4x}{1-sin^6x-cos^6x}=\frac{2cos^2x}{3}[/tex] I'm going with that because it actually solves pretty easily, which is usually the way this goes. Begin by cross multiplying:
[tex]3(1+sin^4x-cos^4x)=2cos^2x(1-sin^6x-cos^6x)[/tex] and distribute:
[tex]3+3sin^4x-3cos^4x=2cos^2x-2cos^2xsin^6x-2cos^8x[/tex] and then break up the powers of sin into squared sines:
[tex]3+3[sin^2x*sin^2x]-3cos^4x=2cos^2x-2cos^2x[sin^2x*sin^2x*sin^2x]-2cos^8x[/tex] and use the Pythagorean identity to change those sines into cosines:
[tex]3+3[(1-cos^2x)(1-cos^2x)]-3cos^4x=2cos^2x-2cos^2x[(1-cos^2c)(1-cos^2x)(1-cos^2x)]-2cos^8x[/tex]
and the FOIL out those terms inside the square brackets:
[tex]3+3[1-2cos^2x+cos^4x]-3cos^4x=2cos^2x-2cos^2x[1-3cos^2x+3cos^4x-cos^6x]-2cos^8x[/tex]
and distribute again on both sides to get rid of the brackets entirely:
[tex]3+3-6cos^2x+3cos^4x-3cos^4x=2cos^2x-2cos^2x+6cos^4x-6cos^6x+2cos^8x-2cos^8x[/tex]
and combining like terms cancels a lot of that out to leave:
[tex]6-6cos^2x=-6cos^6x+6cos^4x[/tex] and get everything on one side to factor:
[tex]0=-6cos^6x+6cos^4x+6cos^2x-6[/tex] and factor out the -6:
[tex]0=-6(cos^6x-cos^4x-cos^2x+1)[/tex] and now we'll factor by grouping, so grouping everything together to get ready for that:
[tex]0=-6[(cos^6x-cos^4x)-(cos^2x+1)][/tex] and begin the factoring:
[tex]0=6[cos^4x(cos^2x-1)-1(cos^2x-1)][/tex] and continuing the factoring:
[tex]0=-6(cos^2x-1)(cos^4x-1)\\0=-6(cos^2x-1)(cos^2x-1)(cos^2x+1)[/tex] and by the Zero Product Property (and we won't list that duplicated factor cuz it's not necessary):
[tex]cos^2x-1=0[/tex] or [tex]cos^2x+1=0[/tex]
Solving the first:
[tex]cos^2x=1[/tex] so
x = 0 + 2kπ and solving the second one:
[tex]cos^2x=-1[/tex] which is not solvable over the real number system.
So x = 0 + 2kπ
and I really hope that's what you were looking for!
