the difference between -2 and 2 is 4
-2 , -1, 0, 1, 2,
Answer:
4
Step-by-step explanation:
Q and T are on the same line.
-9 is the x value for both points.
All you are left with is the distance between -2 and 2.
Subtract and take absolute value if you come up with a negative answer.

Beth needs to fertilize her flowerbed, which is in the shape of a regular pentagon. A bag of fertilizer states that it can fertilize up to 150 square feet, but Beth is not sure how many bags of fertilizer she should buy. Each side of the pentagon is 15 feet long
Answer: he should buy 3 bags
Step-by-step explanation:
In order to determine the area of the flower bed which has the shape of a Pentagon, we would apply the formula for determining the area of a polygon which is expressed as
Area = (perimeter × apotherm)/2
The apotherm is the perpendicular distance from the center of the polygon. The formula for determining the apotherm is
Apotherm = S/2tan(180/n)
Where
S = side length of the polygon
n = number of sides of the polygon.
From the information given,
S = 15 feet
n = 5
Apotherm = 15/2tan(180/5) = 10.3 ft
Perimeter = side length × number of sides
Perimeter = 15 × 5 = 75 ft
Therefore,
Area of the Pentagon = 75 × 10.3/2 = 386.25 ft²
A bag of fertilizer states that it can fertilize up to 150 square feet. Therefore, the number of bags that he can buy is
386.25/150 = 2.575 bags
He should buy approximately 3 bags
A parabola intersects the xxx-axis at x=3x=3x, equals, 3 and x=9x=9x, equals, 9.
What is the xxx-coordinate of the parabola's vertex?
Answer:
x=6
Step-by-step explanation:
Given the x-intercepts of a parabola: [tex]x_1=3, x_2=9[/tex]
The equation of symmetry at the parabola's vertex is x=h
Where [tex]h=\dfrac{x_1+x_2}{2}[/tex]
In this case,
[tex]h=\dfrac{3+9}{2}=6[/tex]
Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.
The vertex of a parabola is the minimum or maximum point of the parabola.
The x-coordinate of the vertex is 6
The intersection points are given as:
[tex]\mathbf{x_1 = 3,\ x_2 = 9}[/tex]
The x-coordinate of the parabola is calculated as:
[tex]\mathbf{x = \frac{1}{2}(x_1 + x_2)}[/tex]
So, we have:
[tex]\mathbf{x = \frac{1}{2}(3 + 9)}[/tex]
[tex]\mathbf{x = \frac{1}{2}(12)}[/tex]
Simplify
[tex]\mathbf{x = 6}[/tex]
Hence, the x-coordinate of the vertex is 6

victor wants to buy fertilizer for his yard. the yard measures 45 feet by 50 feet. the directions on the bag of fertilizer says that one bag will cover 1,220 sq ft. how many bags of fertilizer should victor buy to be sure that he cover the entire yard
Answer:
He'll need 2 bags to cover his yard.
Step-by-step explanation:
To solve this problem we first need to calculate the area of Victor's yard. It seemes by the dimmensions given that his yard have a rectangular shape, it's area is given by:
yard area = length*width
yard area = 45*50 = 2250 square feet
Since each bag will cover 1220 square feet, to calculate how many bags are needed for his yeard we need to divide the yard's area by the area each bag can cover. This is shown below:
number of bags = yard area/ bag area = 2250/1220 =1.84
Since he can't buy 0.84 bags we will round the number of bags to 2.

Based on the relationship of the intercepted arcs of congruent chords, the measure of arc JM is: C. 132°.
What is the Measure of Intercepted Arcs of Equal Chords?If two chords are congruent, then the corresponding arcs bounded by the chords will have equal measure too.
Thus, KL = LM, therefore:
7x + 7 = 8x - 3
Solve for x
7x - 8x = -7 - 3
-x = -10
x = 10
Arc JM = 13x + 2

Mathematically, the square of a number, is the power of 2 to the base of that number, or the exponent 2 to the base of that number.
Such as :
The Square of 5.
=5²
= 5*5 = 25.
In thesame vain, the SQUARE of a number is to the power 2 of that number.
Hence, the SQUARE ROOT, of any number is the ROOT 2 , to that number. Such that:
Square roots of 5:

For other expression other than 2, the rational expression will be a function of the value before the root.
Such that:
1. ³√5 = 5 ^ ⅓
2. ³√ 12 = 12 ^ ⅓
3. ³√8 = 8 ^ ⅓ = 2
4. ⁴√ 16 = 16 ^ ¼ = 2

x = x equals negative 5 plus or minus the square root of seventeen all over 2
Answer:
A. x equals 5 plus or minus the square root of thirty-three all over 2
Step-by-step explanation:
Let's move all the terms to one side:
[tex]x^2=5x+2[/tex]
[tex]x^2-5x-2=0[/tex]
Now, we want to use the quadratic formula, which states that for a quadratic equation of the form [tex]ax^2+bx+c=0[/tex], the roots can be found with the equation: [tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] or [tex]x=\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex].
Here, a = 1, b = -5, and c = -2, so plug these in:
[tex]x=\frac{-(-5)+\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5+\sqrt{25+8} }{2}=\frac{5+\sqrt{33} }{2}[/tex]
OR
[tex]x=\frac{-(-5)-\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5-\sqrt{25+8} }{2}=\frac{5-\sqrt{33} }{2}[/tex]
Thus, the answer is A.

The distribution of number of hours worked by volunteers last year at a large hospital is approximately normal with mean 80 and standard deviation 7. Volunteers in the top 20 percent of hours worked will
receive a certificate of merit. If a volunteer from last year is selected at random, which of the following is closest to the probability that the volunteer selected will receive a certificate of merit given that the
number of hours the volunteer worked is less than 90?
A 0.077
B 0.123
C 0 0.618
D 0.618
E 0.923
Answer:
B. 0.123
Step-by-step explanation:
You want the probability that hours are in the top 20% of a normal distribution with µ = 80 and σ = 7, if the number of hours worked is less than 90.
Z-scoresThe number of hours will be in the top 20% if it exceeds the 80th percentile. That value is found using the inverse normal distribution.
P(Z) > 0.8 ⇒ Z ≈ 0.8416
The Z-score associated with 90 hours is ...
Z = (X -µ)/σ = (90 -80)/7 ≈ 1.4286
ProbabilityThen the probability of interest is ...
P(0.8416 < Z < 1.4286) ≈ 0.1234
The probability the volunteer will receive a certificate is about 0.123, choice B.
__
Additional comment
We have found the probability indicated above, which matches one of the answer choices. The wording of the question suggests that a conditional probability is needed:
P(Z>0.8416 | Z<1.4286) . . . hours in top 20% given they are less than 90
That value would be ...
P(Z>0.8416 | Z<1.4286) = P(0.8416 < Z < 1.4286) / P(Z < 1.4286)
P(Z>0.8416 | Z<1.4286) = 0.1234/0.9234 ≈ 0.134

Step-by-step explanation:
Best Buy would sell the 26" LED TV, which they bought from SONY for $138 each, at $237.36 in the store after adding a 72% mark-up.
Explanation:The question is asking how much a 26" LED TV, bought by Best Buy from SONY for $138 each, would cost in the store if Best Buy charges 72% more than this. We can solve this problem using basic multiplication and addition.
First, calculate 72% of $138, which is $138 * 0.72 = $99.36. This is the amount added to $138 to get the price in the store.Next, add this amount to $138 to get the store price: $138 + $99.36 = $237.36.So, this 26" LED TV from SONY would cost $237.36 in Best Buy's store.

Mr. Smith started his own business making sweatshirts. It costs him $15 for the sweatshirt, $3 for the designs, and $.50 for delivery. If he sells the sweatshirts for $26 in his store, what is the return on investment on each sweatshirt?
Answer:
$7.5 is the ROI on each sweatshirt
Step-by-step explanation:
In this question, we are asked to calculate ROI for a businessman who sells sweatshirts.
To calculate the profit we need to subtract the total cost incurred form manufacture to delivery and subtract bogus from the cost at which he sells the shirts.
Mathematically let’s calculate the cost from production to delivery.
That would be ;
$15 + $3 + $0.5 = $18.5
sales price is $26
His ROI will be $26 - $18.5 = $7.5

If no fallacy is committed, write "no fallacy." Todd Burpo, the best-selling author, argues in his book that heaven is real and that his son Colton met Jesus and John the Baptist in a near-death experience. But it’s clear that Burpo says these things only to sell lots of books. Therefore, his arguments have no merit.
The argument discrediting Todd Burpo uses an ad hominem fallacy and a fallacy of weak induction called circumstantial ad hominem, focusing on Burpo's potential financial gain instead of the validity of his claims.
The argument presented commits a couple of logical fallacies.
Firstly, it commits the ad hominem fallacy, which is a type of fallacy of relevance.
This fallacy occurs when the arguer attacks the person making the argument instead of the argument itself.
In this case, discrediting Todd Burpo because he has a financial motivation does not address the actual content of his claims about heaven.
Secondly, there's a fallacy of weak induction known as circumstantial ad hominem.
Here, the suggestion is that Burpo’s circumstances (wanting to sell books), rather than evidence, make his claims unworthy of consideration, which is an insufficient basis to deny the merits of his arguments.
While the argument does not prove the existence of a supernatural deity, dismissing it because of the author's potential financial gain uses inappropriate grounds that do not speak to the truth or falsity of the actual claim, thus making it an invalid critique.
The burden of proof demands that a claim be established through reason and evidence, and this fallacy does not appropriately engage with either.

You have one type of nut that sells for $3.00/lb and another type of nut that sells for $5.40/lb. You would like to have 7.2 lbs of a nut mixture that sells for $4.60/lb. How much of each nut will you need to obtain the desired mixture?
Answer: 2.4 pounds of the type of nut that sells for $3.00/lb and 4.8 pounds of the type of nut that sells for $5.40/lb would be needed.
Step-by-step explanation:
Let x represent the number of pounds of the type of nut that sells for $3.00/lb that you would need.
Let y represent the number of pounds of the type of nut that sells for $5.40/lb that you would need.
You would like to have 7.2 lbs of a nut mixture. It means that
x + y = 7.2
The mixture would sell for $4.60/lb. It means that the cost of the mixture would be
4.6 × 7.2 = $33.12
This means that
3x + 5.4y = 33.12- - - - - - - - - 1
Substituting x = 7.2 - y Intl equation 1, it becomes
3(7.2 - y) + 5.4y = 33.12
21.6 - 3y + 5.4y = 33.12
- 3y + 5.4y = 33.12 - 21.6
2.4y = 11.52
y = 11.52/2.4
y = 4.8
x = 7.2 - y = 7.2 - 4.8
x = 2.4
