What is the formula for finding the perimeter of a polygon?
Answer:
P=n*s
Step-by-step explanation:
n is the number of sides and s is the length of any one side.
Answer:
It depends on the polygon.
Perimeter is the distance around a figure, so the formula changes for what type of polygon it is. For example, a square would be 4l or the length of one side times 4.
To find the perimeter for any polygon, regular or irregular, use the distance formula for each side. Then add all values together.
The distance formula is [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where [tex](x,y)[/tex] is one edge and [tex](x_2 , y_2)[/tex] is another edge, both belonging to the same side. This formula calculates the unit length of a side of your choice. For irregular figures, you have to use this formula for every side. For regular figures, just multiply the distance by how many sides there are.

What is the vertex of f(x) = |x + 8| – 3?
(-8,-3)
(-8,3)
(8,-3)
(8,3)
The vertex of the function f(x) = |x + 8| - 3 is (-8, -3).
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given is an absolute value function,
f(x) = |x + 8| – 3
For a function of the form,
f(X) = a |x - h| + k, the vertex of the function is the point (h, k).
Comparing the equation with the given one,
f(x) = |x + 8| – 3
f(x) = |x - (-8)| + (-3)
So we get, h = -8 and k = -3.
So vertex is (-8, -3).
Hence the vertex is (-8, -3).

Learning math. The Core Plus Mathematics Project (CPMP) is an innovative approach to teaching mathematics that engages students in group investigations and mathematical modeling. After field tests in 36 high schools over a three-year period, researchers compared the performances of CPMP students with those taught using a traditional curriculum. In one test, students had to solve applied algebra problems using calculators. Scores for 320 CPMP students were compared with those of a control group of 273 students in a traditional math program. Computer software was used to create a confidence interval for the difference in mean scores (Journal for Research in Mathematics Education, 31, no. 3, 2000).
Conf. level: 95%
Variable: µ(CPMP) — µ(Ctrl)
Interval: (5.573, 11.427)
a) What is the margin of error for this confidence interval?
b) If we had created a 98% confidence interval, would the margin of error be larger or smaller?
c) Explain what the calculated interval means in this context.
d) Does this result suggest that students who learn mathematics with CPMP will have significantly higher mean scores in applied algebra than those in traditional programs? Explain.

It is a
Scalene and Right angle
Can someone tell me if this is a adjacent ,vertical or linear
Answer:
linear
Step-by-step explanation:
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
sum of angles on a straight line is 180° thus linear angle is also be 180° when the two angles a and b combine
What is m∠1? Help me, please
Answer:
32°
Step-by-step explanation:
Since the 147° angle and ∠2 form a Linear pair, sum of these angle must be 180°
147° + ∠2 = 180°
∠2 = 180° - 147° [subtracting 147° from both sides]
∠2 = 33°
Since all internal angles of a triangle add up to 180°,
∠1 + ∠2 + 115° = 180°
∠1 + 33° + 115° = 180°
∠1 + 148° = 180°
∠1 = 180° - 148° [subtracting 148 from both sides]
∠1 = 32°

f(x)=x^2−10x+21 in factored form
Answer:
(x-7)(x-3)
Step-by-step explanation:
The factored form of f(x)=x^2-10x+21 is (x-7)(x-3). In order to find the factored form, you have to find what values add to -10, yet multiply to 21. So, the values that add to -10 and multiply to 21 are -7 and -3. x and x multiply to x^2.
In conclusion, the factored form of f(x)=x^2-10x+21 is (x-7)(x-3).

Which number line represents the solution to the inequality 125x + 200 > 1,200?
what is 10 x 567 divded by 2 x 45
Answer:
63
Step-by-step explanation:
Answer: 63
Step-by-step explanation: First, you would do 10 x 567.
10 x 500 = 5000
10 x 60 = 600
10 x 7 = 70
5000 + 600 + 70 = 5670
Next, you find out 2 x 45.
2 x 45 is equivalent to 45 + 45.
45 + 45 = 90
Finally, you divide the product by the product - 5670 divided by 90.
The answer to that is 63.

The drama club sells tickets to their spring play. They sell 180 tickets for a
total of $2,248. Adult tickets cost $14 each. Student tickets cost $10 each.
How many adult tickets and how many student tickets do they sell?
Show your work.
The number of adult and student tickets are 112 and 68 respectively
How to determine the number of adult and student tickets?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Set up equations to represent the problem.
Let the A and S represent the numbers of adult and student ticket respectively. So we can write:
A + S = 180 --- (1)
14A + 10S = 2248 --- (2)
From (1):
A = 180 - S ----(3)
Put (3) in (2):
14A + 10S = 2248
14(180 - S) + 10S = 2248
2520 - 14S + 10S = 2248
2520 - 4S = 2248
4S = 2520 - 2248
4S = 272
S = 272/4
S = 68
Put S = 68 in (3):
A = 180 - S
A = 180 - 68
A = 112
