Answer:
[tex]m=1[/tex]
Step-by-step explanation:
Slope can be calculated using following formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] ----------- (1)
Here
[tex](x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)[/tex]
Substitute values in equation (1)
[tex]m=\frac{2-1}{2-1}[/tex]
[tex]m=1[/tex]
Find the 6th term of an arithmetic sequence given that a(1)= 12 and a(n)= a(n-1)-23
Answer:
-103
Step-by-step explanation:
a(1) = 12
a(n) = a(n-1) - 23
a(2) = a(1) - 23
= 12 - 23
= -11
Common difference (d) = a(2) -a(1) = -11 - 12 = -23
a(n) = a1 + (n-1)d
a(6) = 12 + 5 * (-23)
= 12 - 115
= -103

what the heck is circumference???
Answer:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
Also In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
Step-by-step explanation:
Most websites of information talk about this, but a simple example is " 1 : the perimeter of a circle The circle measures 22 inches in circumference. 2 : the external boundary or surface of a figure or object : periphery from the center to the circumference of the sphere."

soo elimination method just means we want to cancel out on of the variable by subtracting of add the entire equations to each other... there is another method but this one is pretty good to learn with.
system 1
2x + 2y = -2
3x - 2y = 12
since there is already an easy way to get rid of the y variable lets just add the two equations together, just add term by term
5x + 0y = 10
if you notice .. just by making an imaginary column.. of each term.. you can just do that single piece by it self.... 2x + 3x = 5x and 2y +(-2y) = 0 and -2 + 12 = 10 :)
so now I can rewrite our new equation
5x = 10 I can solve this one with my eyes closed :D (10/5 = 2 )
x =2 :P
now , since we know x .. just plug in the known value of x into the 1st equations...
2(2) +2y = -2
4 + 2y =-2
2y = -2-4
2y = -6
y = - 3 :) ( I had to keep my eyes open that time b/c there was a minus sign floating about and those are too easy to mess up on .. when you do.. don't worry everyone does )
so we know
x = 2 and y = -3 :)
I'll go a little faster on 2.. and I see 3 is good for you to practice on.. just ask later if you have questions on that one.
system 2
4x - 2y = -1
-4x + 4y = - 2
add them again to get rid of the x term
0x +2y = -3
y = - 3/2
plug in y
4x - 2(-3/2) = -1
4x +3 = -1
4x = -1 - 3
4x = -4
x = -1
they are being nice and making them easy to start out.. you try system 3

What is the value of g?
If you could explain why I would be super grateful!

Answer: G is 31 degrees
Step-by-step explanation: that angle is a right angle which means it measures 90 degrees. if we subtract the given measurement from 90 we get 31
Answer:
31
Step-by-step explanation: both sides added together need to equal 90 because it is a right angle so 90-59=31
A machine can make 56 parts in 4 hours.It can also make 70 parts in 5 hours. Write an equation that relates the number of parts the machine can make and the time in hours.Predict how many parts the machine can make in 9 hour and 30 minutes.
Answer:
126 parts in 9 and a half hours
Step-by-step explanation:
56 parts in 4 hours
that means 56 parts in 240 mins
9 hours and 30 minutes in minutes is 570 minutes
56m parts:240 mins
540 mins
to get to 540 from 240, you multiply by 2.25.
you can work this out by doing 540 divided by 240
now, multiply 56 by 2.25.
the answer is 126 parts

The correct option for Kristen's population of interest would be "All students at her high school."
Here, we have,
The population of interest refers to the specific group of individuals that the researcher wants to draw conclusions about or make inferences regarding a particular research question.
In this case, Kristen is specifically interested in the opinions of students at her high school regarding the proposed new school hours.
Therefore, her population of interest is limited to the students within her own high school.
The other options mentioned such as "All members of the school board," "All teachers at her school,"
"All students in the school district,"
and "All high school students in the state" represent broader or different groups that are not the specific focus of Kristen's investigation.
Hence, in this case, it is concluded that the correct answer is "All students at her high school."

Fred has 5 3/4 feet of yarn he will use 1/8 foot of yarn for each decoration he makes what's the greatest number of decorations can Fred make
Answer: Tthe greatest number of decorations can Fred make = 46
Step-by-step explanation:
Total yarn = [tex]5\dfrac34[/tex] feet [tex]=\dfrac{23}{4}[/tex] feet
Yarn required for each decorartion = [tex]\dfrac18[/tex] foot
The greatest number of decorations can Fred make = (Total yarn) ÷ (Yarn required for each decorartion)

In triangle ABC, what is the measure of b if a = 6, C = 4,
and B = 75°?
A. 5.64
B. 6.29
C. 6.78
D. 7.02
Given:
In triangle ABC, a = 6, c = 4, and B = 75°.
To find:
The measure of b.
Solution:
According to the Law of Cosine:
[tex]b^2=a^2+c^2-2ac\cos B[/tex]
Substituting the given values in the above formula, we get
[tex]b^2=(6)^2+(4)^2-2(6)(4)\cos (75^\circ)[/tex]
[tex]b^2=36+16-48(0.2588)[/tex]
[tex]b^2=52-12.4224[/tex]
[tex]b^2=39.5776[/tex]
Taking square root on both sides, we get
[tex]b=\sqrt{39.5776}[/tex]
[tex]b=6.291073[/tex]
[tex]b\approx 6.29[/tex]
The measure of side b is 6.29 units.
Therefore, the correct option is B.
