Answer:
5. (a) Polygon Angle-Sum Theorem
6. (c) 360°
Step-by-step explanation:
5. The sum of the angles is shown as 540°. The theorem that tells you the sum of angles in an n-gon is the "polygon angle sum theorem."
__
6. The sum of exterior angles around any (convex) polygon is 360°. (This is where the angle-sum theorem comes from.)
Find x and y from the triangle.
Answer:
x = 39
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 12 + 90 = 180
2x + 102 = 180 ( subtract 102 from both sides )
2x = 78 ( divide both sides by 2 )
x = 39
Then
x = 39°
x + 12 = 39 + 12 = 51°
For his phone service, Ivan pays a monthly fee of $25, and he pays an additional $0.07 per minute of use. The least he has been charged in a month is $103.82.
What are the possible numbers of minutes he has used his phone in a month?
Use m for the number of minutes, and solve your inequality for m.
Answer:
25+(0.07xm)=103.82 m=1126
y = (4x+4)^1/2 at x=2
9514 1404 393
Answer:
2√3 ≈ 3.4641016
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
(4x +4)^(1/2) at x=2 is ...
(4·2 +4)^(1/2) = 12^(1/2) = 2√3 ≈ 3.4641016
__
Additional comment
If you really mean (4x+4)^1/2, then you have 12^1/2 = 12/2 = 6.
If the exponent is 1/2, it needs to be in parentheses.
1. Find the distance between the points A(1,0) and B(0,0).
Answer:
1
Step-by-step explanation:
Since the y value is the same, we only need to find the distance between the x points
1-0 = 1
The distance between the point is 1
Answer : 1 unit.
Explanation: Since ( 0,0 ) is at 0 on the x axis, ( 1,0 ) is one unit to the right of 0, 1.

At the movie theatre, child admission is $5.80 and adult admission is $9.70. On Wednesday, 171 tickets were sold for a total sales of $1296.00. How many
child tickets were sold that day?
Answer:
93 child tickets
Step-by-step explanation:
Create a system of equations where c is the number of child tickets sold and a is the number of adult tickets sold:
c + a = 171
5.80c + 9.70a = 1296.00
Solve by elimination by multiplying the top equation by -9.7:
-9.7c - 9.7a = -1658.7
5.8c + 9.7a = 1296
Add these together and solve for c:
-3.9c = -362.7
c = 93
So, 93 child tickets were sold.
Which word describes the relationship of the points (3, 1)
and (3, 6)?
OA) collinear
OB) parallel
C) perpendicular
OD) coincident
9514 1404 393
Answer:
A) collinear
Step-by-step explanation:
"Parallel" and "perpendicular" are descriptors of pairs of lines and planes. They do not apply to pairs of points.
The two points have different coordinates, so are distinct, rather than coincident.
Of these words, the only applicable choice is "collinear."
__
Additional comment
Any pair of distinct points is collinear. Two points define a line, and two points on the same line are collinear.

What will be the value of median of a moderately asymmetrical distribution? If the mean and mode are 30 and 24 respectively.
The mean, the median and the mode are measures of central tendency, and they are related in some many ways, depending on the type of distribution.
The median of the moderately asymmetrical distribution is 26
The given parameters are:
[tex]Mean = 30[/tex]
[tex]Mode = 24[/tex]
For a moderately asymmetrical distribution, the mean, median and mode are related by the following equation:
[tex]Mode = 3 * Median - 2 * Mean[/tex]
Substitute known values
[tex]30= 3 * Median - 2 * 24[/tex]
[tex]30= 3 * Median - 48[/tex]
Collect like terms
[tex]3 * Median =30+ 48[/tex]
[tex]3 * Median =78[/tex]
Divide both sides by 3
[tex]Median =26[/tex]

Answer:
All of area is πr²
Step-by-step explanation:
and we should write the area kind of radian. So if all area is π*(12)²= 144π - this for 360°- and 240° is 96π
but we must add area of the triangle which has two same side and has 6 high so it's area is 6*12√3/2 = 36✓3
our answer is 96π+ 36✓3

The cost is 23$ when___coolers are produced
9514 1404 393
Answer:
97
Step-by-step explanation:
We want to find x when C = 23.
23 = 0.005x^2 -0.35x +10
2600 = x^2 -70x . . . . . . subtract 10, multiply by 200
2600 +35^2 = (x -35)^2 . . . . complete the square
61.847 +35 = x . . . . . . . square root, add 35 (use the positive result only)
x ≈ 97 . . . . rounded to integer
The cost is $23 when 97 coolers are produced.

C. symmetric with respect to the origin
Step-by-step explanation:
A graph must pass the vertical line test to be called the graph of a function. No function will ever be symmetrical with respect to the x-axis, because that would mean it fails the vertical line test.
An even function is symmetrical about the y-axis. An even function has the characteristic that ...
f(-x) = f(x) . . . . an even function
An odd function is symmetrical about the origin. An odd function has the characteristic that ...
f(-x) = -f(x)
__
The given function is f(x) = -1/x. Then the value of f(-x) is ...
f(-x) = -1/-x = 1/x = -f(x)
The given function is an odd function, so is symmetrical about the origin.

Step-by-step explanation:
A linear equation means the equation of straight line.
The formula for equation of straight line in slope intercept form is y=mx+c
where, m is the slope of line and c is the y intercept
The formula for equation of straight line in double intercept form is x/a+y/b=1
The formula for equation of straight line in normal form is xcos α + y cos α=p
