Answer:
This is truly false.
When determining which x-values would make an expression undefined, you do need to include the factors you canceled out.
Step-by-step explanation:
When working with functions, it is said to be undefined when the value of the function doesn't take on a value, and this occurs when the denominator is equal to 0.
Take for example
(x-2)/(x-2)
This simple function can be simplifted further by cancelling out the factors to get 1, but that doesn't change the fact that, at x=1, this function becomes undefined.
Because, the values of x can vary and can take on values that can make the denominator to be 0, factors that are cancelled need to be included in checking for where a function is undefined.

Step-by-step explanation:
The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c).
circle diameter radius
A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d)
Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).
The circumference of a circle is found using this formula:

if xh=10 feet and mxy =100 degrees then determine the arc length of xy
Answer:
The arc length XY is equal to [tex]\frac{50}{9}\pi\ ft[/tex] or [tex]17.4\ ft[/tex]
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the circumference of the circle H
The circumference is given by the formula
[tex]C=2 \pi r[/tex]
we have
[tex]r=xh=10\ ft[/tex]
substitute
[tex]C=2 \pi (10)\\C=20\pi\ ft[/tex]
step 2
we know that
The circumference of a circle subtends a central angle of 360 degrees
so
using proportion
Find out the length of the arc xy if the central angle is equal to 100 degrees
Remember that
[tex]m\angle XHY=arc\ XY=100^o[/tex] ---> by central angle
[tex]\frac{20\pi}{360^o}=\frac{x}{100^o}\\\\x=20\pi(100)/360\\\\x=\frac{2,000}{360}\pi\ ft[/tex]
Simplify
[tex]x=\frac{50}{9}\pi\ ft[/tex] ----> exact value
To find out the approximate value
assume
[tex]\pi=3.14[/tex]
substitute
[tex]x=\frac{50}{9}(3.14)=17.4\ ft[/tex] ----> approximate value
therefore
The arc length XY is equal to [tex]\frac{50}{9}\pi\ ft[/tex] or [tex]17.4\ ft[/tex]
The arc length is 17.4 feet
Arc length of circle:The arc length is given as,
[tex]\theta=\frac{arc}{radius}[/tex]
From given figure, It is observed that radius is 10 feet and angle is 100 degree.
Convert 100 degree into radian,
[tex]100degree=100*\frac{\pi}{180} =1.74 radian[/tex]
Substitute values in above relation.
[tex]1.74=\frac{arc}{10}\\ \\arc=1.74*10=17.4feet[/tex]
Thus, the arc length [tex]xy[/tex] is 17.4 feet

How many 3 number combinations are possible if you can't repeat the numbers? The numbers range from 0-39
Answer: 49600
Step-by-step explanation: There are 40 ways to choose the first number
and there are 40 ways to choose the second number.
Now we take some examples to determine how many choices there are for
the third number
If the second number is 23, then the 3rd number cannot be any of these
9 numbers 19,20,21,22,23,24,25,26,or 27, since they are not at least 5
numbers away from 23. Same for all other 40 second numbers.
Let's look at a second example which includes some on both sides of 0.
If second number is 2, we couldn't choose any of the 9 numbers 38,39,0,1,2,3,4,5,6.
So thats 40-9 or 31 choices for the 3rd number.
Answer 40*40*31 = 49600 ways.
what is a/8 - 7(3) = 4a - 78(b)
solve for b pls
Answer:
31a/624 +7/26 = b
Step-by-step explanation:
a/8 - 7(3) = 4a - 78(b)
Multiply
a/8 - 21 =4a -78b
Multiply each side by 8 to get rid of the fractions
8(a/8 - 21) =8(4a -78b)
a - 168 = 32a -624b
Subtract 32a from each side
a -32a -168 = 32a -32a -624b
-31a -168 = -624b
Divide each side by -624
(-31a -168)/-624 = -624b/-624
(31a+168)/624 = b
31a/624 +7/26 = b
Answer:
b = (31a + 168)/624
Step-by-step explanation:
a/8 - 7(3) = 4a - 78(b)
78b = 4a - a/8 + 21
78b = (32-1)a/8 + 21
78b = (31a + 21(8))/8
78b = (31a + 168)/8
b = (31a + 168)/8 × 1/78
b = (31a + 168)/624

Erik buys 2.5 pounds of cashews.If each pound of cashews cost $7.50, how much will he pay for the cashews
Erik will pay $18.75 for 2.5 pounds of cashews because the price is $7.50 per pound, and the cost is calculated by multiplying the price per pound by the number of pounds.
To calculate how much Erik will pay for 2.5 pounds of cashews at a rate of $7.50 per pound, you simply multiply the number of pounds of cashews by the price per pound.
The formula to determine the cost is: Total Cost = Price per Unit x Quantity.For Erik's purchase, this would be: Total Cost = $7.50 x 2.5.Let's do the calculation:
First, multiply 7.50 by 2.5, which equals 18.75.This means Erik will pay $18.75 for the cashews.What is the area of the triangle?

Which order pair is a solution of this equation. 5x+y=-25
Answer:
(-5,0) or (0,-25) is another solution
Step-by-step explanation:
Do you have a list of choices? If not, you could choose random choices for x and y to determine if they are solutions. Start by letting y = 0. We see that x = -5, so (-5, 0) is a solution to this equation. In fact, it represents the x-intercept of this line. Now, let x = 0. We now see that y = -25, so (0, -25) is another solution to the equation of this line. This coordinate pair is the y-intercept of the line. Try using other values of x and y to see if you can come up with other solutions to this equation.
Answer:
(-5,0)

Which strategy would you choose to expand (x+11)(2x+3) and write an equivalent expression
Answer:
Step-by-step explanation:
Given the expression (x+11)(2x+3)
We want to expand it and write equivalent expression
Generally if we want to expand an expression we will take one of the expression in one bracket and multiply with the other bracket and then take the other expression and multiply it with the other
E.g, (a+b) × (c + d)
Then, we take a × (c+d) and also b × (c+d)
We can do it the other way round too and it will give the same results.
So, applying this to the given expression
(x+11)(2x+3)
x(2x+3) + 11(2x+3)
2x² + 3x + 22x + 33
2x² + 25x + 33
Then, the equivalent expression is 2x² + 25x + 33
(x + 11)(2x + 3) = 2x² + 25x + 33

There are 4 teams in a soccer tournament. Each team plays each of the other teams exactly once. In each match, the winner receives 3 points and the loser receives 0 points. In the case of a tie, both teams receive 1 point. After all the matches have been played, which of the following total number of points is it impossible for any team to have received?
Answer:
8 points
Step-by-step explanation:
Given that there are 4 teams and Each team plays each of the other teams exactly once, then each team plays 3 matches. The possible points after 3 matches are:
0: 3 lost
1: 2 lost, 1 tied
2: 2 tied, 1 lost
3: 3 tied
4: 1 won, 1 lost, 1 tied
5: 1 won, 2 tied
6: 2 won, 1 lost
7: 2 won, 1 tied
9: 3 won
The answer is 8 points.
Since there are 4 teams in a soccer tournament, and each team plays each of the other teams exactly once, and in each match, the winner receives 3 points and the loser receives 0 points, while in the case of a tie, both teams receive 1 point, to determine, after all the matches have been played, which total number of points is it impossible for any team to have received, the following mathematical logical reasoning must be performed:
0 points = 3 losses = possible 1 point = 1 draw, 2 losses = possible 2 points = 2 draws, 1 loss = possible 3 points = 1 win, 2 losses or 3 draws = possible 4 points = 1 win, 1 draw, 1 loss = possible 5 points = 1 win, 2 draws = possible 6 points = 2 wins, 1 loss = possible 7 points = 2 wins, 1 draw = possible 8 points = impossible, it takes at least 4 matches to achieve that combination 9 points = 3 wins = possible

It took Skylar a full minute to recall the chain of events that had brought her here,
deep into outer space. She had awoken from her deep, dreamless sleep only a few
moments before. After stretching her unused muscles, she surveyed her
surroundings, recognizing the instruments and equipment around her. Everything
had gone according to plan, and she had been asleep throughout the entire three-
year journey. Now, she had a crucial mission to carry out, one that would influence
the very course of life back on Earth.
This excerpt is the beginning of a longer work. Which describes how the plot will
most likely unfold?

Final answer:
The plot will likely focus on Skylar's crucial mission in outer space, portraying her as an archetypal heroine, with the story revealing the destabilizing condition that led her to this moment.
Explanation:
Based on the excerpt, it's most likely that the plot will involve Skylar embarking on a crucial mission that affects life on Earth, suggesting that the narrative will focus on her as an archetypal heroine. Given that she's just awakened from a three-year journey in deep space, we can infer a narrative structure that will emphasize her actions and decisions in outer space rather than detailing her entire life history or returning home immediately. The story seems poised to dive into the destabilizing condition that brought Skylar into space, likely escalating towards a central conflict related to her mission, while building empathy for her character as she navigates challenges in a foreign environment.
