Answer:
a set is a collection of elements. The elements that make up a set can be any kind of mathematical objects: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets. The set with no element is the empty set; a set with a single element is a
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
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]

Are (2,9) and (-3,-6) both on the line y = 4x + 6? If not, find an equation for the line that does pass through both points.
Answer:
no, y=3x+3
Step-by-step explanation:
plug both points into the equations:
9=4*2 +6 -> 9=8+6, doesn't work-6=4(-3)+6 -> -6=-6, worksone works but the other doesn't so now we find a line through both points
use the formula (y_2-y_1)/(x_2-x_1) to find the slope:
(-6-9)/(-3-2)=-15/-5=3y=3x+b, plug in a point to find b:
9=3(2)+b9=6+bb=3y=3x+3If n - 72 = 36, then what is the value of n?
N - 72 = 36
To solve for n add 72 to both sides of the equation:
N = 108
Answer:
108
Step-by-step explanation:
Add 72+ 36 you will get your answer
The answer is 108
Therefore n= 108
3. Determine the value of x if:
3.1. 75x -15 =5x + 125
3.2. 6(3x - 2) = 7(x + 3) +2
3.3.10/x-3= 8
3.4. x + 7 = 5x - 13
3.5. 20x +4 =4x - 46
Step-by-step explanation:
3.1.
your question
75x-25=5x+125
collect like terms
70x=150
Divide both side by the coefficient of x
70x/70=150/70
70 ti cancel 70 on x side to leave x alone
:. x=150/70 or 2.14
3.2.
6×(3x-2)=7×(x+3)
multiply by the bracket
18x-12=7x+21
collect like terms
18x+7x=21+12
25x=33
divide by the coefficient of x
25x/25=33/25
x=33/25 or 1.32
3.3.
10/x-3=8
cross multiply(know that 8 is /1)
x‐3×8=10×1
8x-24=10
8x=10+24
8x=34
divide both sides by coefficient of x
8x/8=34/8
8x=34/8 or 4.25
3.4.
x+7=5x-13
collect like terms
7+13=5x-x
20=4x
divide both sides by the coefficient of x
20/4=4x/4
5=x
:.x=5
3.5.
20x+4=4x-46
collect like terms
20x-4x=-46-4
16x=-52
divide both sides by the coefficient of x
16x/16=-52/16
:.x=52/16 or 3.25

1+sin^4-cos^4a/1-sin^6-cos^6a=2/3cos^2a
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!

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?
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

Step-by-step explanation:
Kris drives 30 miles to work. For the first x miles, he drives 40 miles per hour. Then he is stuck in traffic and averages only 3 miles per hour the rest of the way. This expression can be used to find the total time Kris spends commuting: 40(x) + 3(30 - x).
Simplify the expressions.
1. 3(30 – x)
2. 40(x) + 3(30 - x)
Answer:
1) -3x + 90
=(3)(30+−x)
=(3)(30)+(3)(−x)
=90−3x
=−3x+90
2) 37x+90
=40x+(3)(30)+(3)(−x)
=40x+90+−3x
Combine Like Terms:
=40x+90+−3x
=(40x+−3x)+(90)
=37x+90

Answer:
The GCF is going to be 2
Step-by-step explanation:
This Is how I find the GCF of 3 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 8, 2 × 2 × 2 = 8
The prime factorization of 18, 2 × 3 × 3 = 18
The prime factorization of 70, 2 × 5 × 7 = 70
The one and THE only common factor is 2, which is going to be the GCF
