Answer:
A
Step-by-step explanation:
The dash (–) is used to set off additional material within a sentence, often in order to emphasize it, to set off appositives that contain commas, or to indicate missing words. ... Some word-processing programs have a mark called an em-dash (longer than a hyphen), which can be used with no space before or after it.

Step-by-step explanation:
A radio station signal covers a circular area out from the signal tower. It gets weaker the farther away your are. The local station WDHS (at location (0,0)) sends it signal out with a coverage radius of 5 miles. 1) Will we hear it better at Zaxby's (2,-4), McDonalds (4, -4), or Dunkin' (-3,3). Show work to support your decision and explain your reasoning. 2) Are any of these location outside the range of the radio station? If so, which one(s). Defend your decision mathematically.
Answer:
1. We would hear better at Dunkin's since its distance from the radio station is the shortest.
2. McDonald's is out of range of the radio station since its distance is greater than the range of the radio station.
Step-by-step explanation:
1) Will we hear it better at Zaxby's (2,-4), McDonalds (4, -4), or Dunkin' (-3,3). Show work to support your decision and explain your reasoning.
We need to find the distance of each point from the tower.
The shorter the distance from the radio station the better the signal.
The distance between two points (x₁, y₁) and (x₂, y₂) is given by d = √[(x₂ - x₁)² + (y₂ - y₁)²].
With (x₁, y₁) = (0, 0) the location of local station WDHS
For Zaxby's distance located at (2, -4) = (x₂, y₂)
So, d₁ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 0)² + (-4 - 0)²]
= √[(2)² + (-4)²]
= √[4 + 16]
= √20
= √(5 × 4)
= √5 × √4
= 2√5
= 4.47 miles
For McDonald's distance located at (4, -4) = (x₂, y₂)
So, d₂ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(4 - 0)² + (-4 - 0)²]
= √[(4)² + (-4)²]
= √[16 + 16]
= √32
= √(16 × 2)
= √16 × √2
= 4√2
= 5.66 miles
For Dunkin's distance located at (-3, 3) = (x₂, y₂)
So, d₃ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 0)² + (-3 - 0)²]
= √[(-3)² + (-3)²]
= √[9 + 9]
= √18
= √(9 × 2)
= √9 × √2
= 3√2
= 4.24 miles
Since Dunkin's distance, d₃ = 4.24 is the least distance from the radio station and is within range of 5 miles, we would hear better at Dunkin's.
2) Are any of these location outside the range of the radio station? If so, which one(s). Defend your decision mathematically.
The radio station is outside of range if its distance is greater than 5 miles. That is, d > 5 miles.
So, we calculate the distance of each point from the radio station.
With (x₁, y₁) = (0, 0) the location of local station WDHS
For Zaxby's distance located at (2, -4) = (x₂, y₂)
So, d₁ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 0)² + (-4 - 0)²]
= √[(2)² + (-4)²]
= √[4 + 16]
= √20
= √(5 × 4)
= √5 × √4
= 2√5
= 4.47 miles
For McDonald's distance located at (4, -4) = (x₂, y₂)
So, d₂ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(4 - 0)² + (-4 - 0)²]
= √[(4)² + (-4)²]
= √[16 + 16]
= √32
= √(16 × 2)
= √16 × √2
= 4√2
= 5.66 miles
For Dunkin's distance located at (-3, 3) = (x₂, y₂)
So, d₃ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 0)² + (-3 - 0)²]
= √[(-3)² + (-3)²]
= √[9 + 9]
= √18
= √(9 × 2)
= √9 × √2
= 3√2
= 4.24 miles
So, for each of the distances calculated above, only McDonald's distance, d₂ = 5.66 miles > 5 miles.
So, McDonald's is out of range of the radio station.
Solve each equation for y (get into slope-intercept/y=mx + b form): a) 10x + 5y = 20 b) 3x - 2y = 10 + 4x
Don't forget to explain how you got the answers.
Answer:
see below
Step-by-step explanation:
We want to solve each equation for y, so y must be alone on one side of the equation.
a) 10x + 5y = 20
Subtract 10x from both sides.
5y = 20 - 10x
Place the x term in front to follow y = mx + b form.
5y = -10x + 20
We want to isolate y completely, so divide both sides by 5. On the right side, be sure to divide each component by 5.
5y/5 = -10/5x + 20/5
y = -2x + 4
This equation is in slope-intercept form.
b) 3x - 2y = 10 + 4x
We can see that y is negative in this original equation. Let's add 2y to both sides to make y positive.
3x = 10 + 4x + 2y
Now we want to isolate y, so subtract 4x from both sides.
3x - 4x = 10 + 2y
Simplify.
-x = 10 + 2y
Isolate y further by subtracting 10 from both sides.
-x - 10 = 2y
Again, we want to isolate y completely, so divide both sides by 2. On the left side, be sure to divide each component by 2.
-x/2 - 10/2 = 2y/2
-1/2x - 5 = y
This looks backwards (although it is in slope-intercept form), so let's rearrange it just to make it more clear.
y = -1/2x - 5
This equation is in slope-intercept form.
Hope this helps!

I need to know how many days buttttt
1 day = 1 2/3
2 days = 3 1/3

6 days = 10
7 days = 11 2/3

This relationship leads to the conclusion that there is no Pythagorean triple of this form that contains the integer 2. Why?
Answer:
suppose 2^2 + b^2 = c^2 with 2 < b < c (it should be clear that this assumption is fine, 12 + 22 = 5 and sqrt(5) is not an integer; 22 + 22 = 8 and sqrt(8) is not an integer). Then c^2 - 4 = b^2 so (c+2)(c-2) = b^2. As b is prime, this means c-2=b or c-2=1 (since c+2 > 1). So either c=b+2 or c=3. The c=3 case can't happen since that would make b^2 = 5 so we are left with c=b+2. Then we have 4 + b^2 = (b+2)2 = b2 + 4b + 4 meaning that b=0. So there are no triples involving 2.
Step-by-step explanation:
A Pythagorean triple of this form cannot contain integer 2 if we add extra 2x²y² because it will increase the value of the coefficient of xy to 4.
The given function:
[tex](x^2-y^2) + (2xy)^2 = (x^2 + y^2)^2[/tex]
This function is expanded as follows;
[tex](x^2-y^2)^2 + (2xy)^2 = (x^2 + y^2)^2\\\\x^4 + y^4 -2x^2y^2 + 4x^2y^2 = x^4 +y^4 + 2x^2y^2\\\\add \ \ (+2x^2y^2) \ to \ both \ sides \\\\x^4 +y^4 +4x^2y^2 = x^4 +y^4 +4x^2y^2[/tex]
In this expanded form of the given function, it is clear that non of the coefficients of x and y contains integer 2 and the supposed coefficient value of xy increase to 4 because of the extra 2x²y² added to the function.
Thus, we can conclude that a Pythagorean triple of this form cannot contain integer 2 if we add extra 2x²y² because it will increase the value of the coefficient of xy to 4.

How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, we want the expression that could be used to predict the number of winners of a game.
Thus, event = event of winning the game, and its probability is evaluated as:
[tex]P(event) = \dfrac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}} \\\\P(\text{Winning the game})= \dfrac{\text{Number of winners}}{\text{Number of contestants}}[/tex]

Answer:
yesno, 2y-x = -16Step-by-step explanation:
standard form is:
Ax+By=C
for problem 2:
y= 1/2 x-8
y- 1/2 x - 8= 0
rearrange:
- 1/2x + y +8 = 0
2 (- 1/2x + y + 8) = 0
-x + 2y + 16= 0
-x + 2y = -16
leading coefficient can't be negative
so multiply everything by -1
x -2y = 16
Answer:
1 yes no
Step-by-step explanation:
1 this is in standard form as it is a linear form and the intercepts can be found
2 This is not in standard form as it is a linear equation and both the x and y intercepts cant be found so must be written in the form AX+BY=C
so
-x + 2y = -6
and leading coefficient cant be - so multiply by -1
so
x-2y=6
