Any one smart enough to answer me (a-b) (a+2b) ?
Answers
Answer:
ok lets do it..
Step-by-step explanation:
You simply multiply out each factor.
So you start by multiplying the a in (a+b) to each term in (a−2b).
You will get a2−2ab as the first portion of the answer.
So now you will do the same with the b in (a+b).
Then you get −2b2+ab.
Now you add a2−2ab and −2b2+ab to get a2−2b2−ab .
i hope it will work....

Answer:
x²+6x-15
Step-by-step explanation:
We are given this expression:
[tex](3x^2+2x-8) - ( 2x^2-4x+7)[/tex]
We want to simplify the expression. First, distribute the negative sign in front of the second set of parentheses. Multiply each term inside the parentheses by -1.
[tex](3x^2+2x-8) + (-1*2x^2) + (-1*-4x) + (-1*7)[/tex]
[tex](3x^2+2x-8) -2x^2+ 4x -7[/tex]
Next, combine like terms. The 2 terms with an x² can be combined, just like the two terms with an x, and the two terms without a variable.
[tex](3x^2-2x^2) + (2x+4x) + (-8-7)[/tex]
[tex]x^2+(2x+4x)+(-8-7)[/tex]
[tex]x^2+6x+(-8-7)[/tex]

Marlon is bowling in a tournament and has the highest average after 5 games, with scores of 210, 225, 254, 231, and 280. In order to maintain this exact average, what must be Marlon's score for his 6th game?
Answers
Answer:
By scoring 240 in the sixth game, Marlon can maintain this exact average
Step-by-step explanation:
The first thing to do here is to calculate the average for the first 5 games.
Mathematically, the average can be calculated by adding all the scores in the games and dividing by 5;
= (210 + 225 + 254 + 231 + 280)/5 = 1200/5 = 240
Now to maintain this average score of 240, we want to know the score she must have in the 6th game.
Let the score be x;
By adding x to the previous total of 1200 before and dividing by the new count of 6, we can work our way to get x.
Mathematically, what we are saying is;
(1200 + x)/6 = 240
6 * 240 = 1200 + x
1440 = 1200 + x
x = 1440 -1200
x = 240
A. Use composition to prove whether or not the functions are inverses of each other. B. Express the domain of the compositions using interval notation.
Answers
Answer:
Step-by-step explanation:
A). If a function 'f' is inverse of another function 'g',
Then f[g(x)] = x = g[f(x)]
In this question the given functions are,
f(x) = [tex]\frac{1}{x-3}[/tex] and g(x) = [tex]\frac{3x+1}{x}[/tex]
Then, f[g(x)] = [tex]\frac{1}{\frac{3x+1}{x}-3}[/tex]
= [tex]\frac{x}{3x+1-3x}[/tex]
= x
Similarly, g[f(x)] = [tex]\frac{(\frac{3}{x-3})+1}{\frac{1}{x-3} }[/tex]
= [tex]\frac{3+x-3}{1}[/tex]
= x
Therefore, Both the functions are inverse of each other.
B). Domain of the compositions of these functions will be a set of all real numbers, (-∞, ∞)

In right triangle ADE,
AD2 = AE2 + DE2
[Using Pythagoras theorem]
Subtracting (ii) from (i), we get
AB2 - AD2 = (AE2 + BE2) - (AE2 + DE2)
AB2 - AD2 = AE2 + BE2 - AE2 - DE2
⇒ AB2 - AD2 = BE2 - DE2

4. A rock is placed in a graduated cylinder with 40-mL of water in it. The water level rises to 60-mL. When placed on a balance scale it takes 54 grams of gram stackers to balance the scale. What is the density of the rock?
Answers
Answer:
2.7 [tex]g/mL[/tex]
Step-by-step explanation:
The density of an object will be its mass over volume.
We know that the mass of this rock is 54 grams because it took 54 grams of gram stackers to balance the scale. If we have a balanced scale, that means the amount of weight on either side is equal. So the mass is 54 grams.
Also, we can tell that the volume of the rock is 20 mL. This is because, according to Archimedes principle, if you put an object in water, the amount of water displacement will be it's volume. So the amount of water displacement is [tex]60-40=20[/tex] mL.
Density is mass over volume, so the density is [tex]54\div20 = 2.7[/tex]. Density is measure in mass over volume, so [tex]g/mL[/tex].
So 2.7 [tex]g/mL[/tex] is the density of the rock.

Find the deriative dy/dx for y=x^2-2x/x^3+3
Answers
Answer:
[tex]\frac{dy}{dx}=(\frac{(2x-2)(x^3+3)-(x^2-2x)(3x^2)}{(x^3+3)^2})[/tex]
Step-by-step explanation:
So we want to find the derivative of the rational equation:
[tex]y=\frac{x^2-2x}{x^3+3}[/tex]
First, recall the quotient rule:
[tex](\frac{f}{g})'=\frac{f'g-fg'}{g^2}[/tex]
Let f be x^2-2x and let g be x^3+3.
Calculate the derivatives of each:
[tex]f=x^2-2x\\f'=2x-2[/tex]
[tex]g=x^3+3\\g=3x^2[/tex]
So:
[tex]\frac{dy}{dx}=(\frac{x^2-2x}{x^3+3})'[/tex]
Use the above format:
[tex]\frac{dy}{dx}=\frac{f'g-fg'}{g^2}\\\frac{dy}{dx}=(\frac{(2x-2)(x^3+3)-(x^2-2x)(3x^2)}{(x^3+3)^2})[/tex]

Answers
Answer:
[tex]JL=56[/tex] [tex]JK=39[/tex] [tex]KL=17[/tex]
Step-by-step explanation:
Your question is not well presented/formatted; however, I can deduce that the question requires that you calculate the following lengths;
JK, KL and JL
Given that
[tex]JL=5x-9[/tex]
[tex]JK=3x[/tex]
[tex]KL=1x+4[/tex]
The relationship between the given parameters is:
[tex]JL = JK + KL[/tex]
Substitute 5x - 9 for JL; 3x for JK and 1x + 4 for KL
[tex]5x - 9 = 3x + 1x + 4[/tex]
Collect Like Terms
[tex]5x - 3x - 1x = 9 + 4[/tex]
[tex]x = 13[/tex]
Now that the value of x has been solved, we can easily get the numeric values of JK, KL and JL by substituting 13 for x
So;
[tex]JL=5x-9[/tex]
[tex]JL=5*13-9[/tex]
[tex]JL=65 - 9[/tex]
[tex]JL=56[/tex]
[tex]JK=3x[/tex]
[tex]JK=3 * 13[/tex]
[tex]JK=39[/tex]
[tex]KL=1x+4[/tex]
[tex]KL=1 * 13+4[/tex]
[tex]KL=13+4[/tex]
[tex]KL=17[/tex]
Hence;
[tex]JL=56[/tex] [tex]JK=39[/tex] [tex]KL=17[/tex]

An object is moving at a speed of 3 kilometers per hour. Express this speed in feet per
minute. Round your answer to the nearest whole number.
Answers
The speed of the object in feet per minute to nearest whole number is 164feet/min
Speed is the ratio of the distance to the time of an object. Mathematically;
Speed = Distance/Time
Given the following
Speed = 3km/hr
Using the conversion ratio
1km = 3280.84feet
3km = x
Cross multiply
x = 3 * 3280.84
x = 9,842.52feet
Convert 1 hour to minute
1 hour = 60minutes
Get the speed in feet per minutes
Speed in feet/minutes = [tex]\frac{9,842.52}{60}[/tex]
Speed in feet/minutes = 164.042 feet/minutes
Hence the speed of the object in feet per minute to nearest whole number is 164feet/min

The speed in feet per minute is 164.
Given the following data:
Speed = 3 kilometers per hour.In this exercise, you're required to convert the value of the speed given in kilometers per hour to feet per minute.
Conversion:
1 kilometer = 3280.84 feet
3 kilometer = X feet
Cross-multiplying, we have;
X [tex]= 3280.84[/tex] × [tex]3[/tex]
X = 9842.50 feet
Since we know that one (1) hour is equal to sixty (60) minutes, we would divide the value of X by 60 in order to convert it to feet per minute.
[tex]X = \frac{9842.50}{60}[/tex]
X = 164.042 feet per minute.
To the nearest whole number;
X = 164 feet per minute

Answer:hi
Step-by-step explanation:Let me first warn you that I CANNOT get the denominators of this problem to go underneath the numerators. It looks good on my answer page but when I click "preview your answer" the denominators are ALL over the place. Grrrrr.
I think the weirdly placed denominators make this explanation hard to understand but you give this a go and see if you understand things. If it is too hard to see, maybe this website will let you instant message me or email me. If so, then I will send you the solution via email. I'm very sorry the denominators are SO scattered.
See what you think of the explanations below but it might help if you write down my answer on paper, so that you can move the number to rest more closely under their proper numerators. :-)
Ok then......
Let's start with your first problem. A quick way to do this work is to cross multiply. Here's what I mean:
__3___ = __6___
r - 1 r + 2
Ok, so you can cross multiply:
3(r + 2) = 6(r - 1) (cross multiply)
3r + 6 = 6r - 6 (use the distributive property)
Now you will have to put the "r" variables on the left side of the equal sign and numbers without variables on the right side of the equal sign. To get 6r from the right side to the left, you can subtract 6r from the right side. If you subtract it from the right, you must subtract it from the left.....
To get 6 from the left side to the right, you can subtract it from the left. If you subtract it from the left, you must subtract it on the right.....
So now you have:
3r - 6r = -6 - 6 This becomes.........
- 3r = -12
Now to solve for "r" you will have to divide by -3. Why? Well, -3r is really saying: -3 times r. The -3 and the r are actually being multiplied together so to isolate the "r" you have to sort of "undo" the multiplication. What is the opposite of multiplication? It's DIVISION. Soooo, you must divide by -3 on both sides. SO you have:
- 3r = -12
r = 4 (-12 divided by -3 is a positive 4)
Now you know "r" equals 4. If we "plug" 4 back into the original equation, we can see the answer is correct. Check this out:
__3___ = __6___ (original equation)
r - 1 r + 2
__3___ = __6___ (substitute "4" in for "r"
4 - 1 4 + 2
__3___ = __6___ (do the math in the denominator area)
3 6
1 = 1 (3/3 equals 1 and 6/6 also equals 1, so our
solution that r = 4 is correct!) :-)
Now to your 2nd problem..........
4/2x-5 = 24/2x
___4___ = __24___
2x � 5 2x
Let's cross multiply again:
4(2x) = 24(2x - 5)
8x = 48x - 120
8x - 48x = - 120
-40x = - 120
(divide both sides by -40)
x = 3
Now let's "plug" 3 in where we had the variable "x" in the original equation to see if we are correct.
___4___ = __24___ (original equation)
2x � 5 2x
___4___ = __24___ (substituted 3 for "x")
2(3) � 5 2(3)
___4___ = __24___
6 - 5 6
___4___ = __24___
1 6
4 = 4
SO once again we have found the correct answer. Yay for us! :-)
I hope this helps. :-)

PART A :A deli receives a large order for sandwiches for a company picnic. The company wants one club sandwich and two regular sandwiches for each person. The company also wants an extra Dagwood sandwich. A club sandwich has $3$ slices of bread. A regular sandwich has $2$ slices. A Dagwood has $5$ slices. If there are $n$ people going to the company picnic, how many slices of bread does the deli need to make this order? Write your answer as a fully simplified expression. Your answer should have the variable $n$ in it exactly once. PART B: Given that the deli ends up using $110$ slices of bread, how many people are going to the company picnic?
Answers
Answer:
Part A:
[tex]7n + 5[/tex]
Part B:
15 people
Step-by-step explanation:
Each person gets one club sandwich and two regular sandwiches. There is one additional Dagwood sandwich.
If a club sandwich has 3 slices, then the total amount of slices needed for [tex]n[/tex] people will be [tex]3n[/tex], since each person has 3 slices.
If a regular sandwich has 2 slices and everybody gets 2 regular sandwiches, then it's represented as [tex]4n[/tex], since everyone has 4 slices each.
Additionally, we have one Dagwood sandwich, which can be represented as 5,, since a Dagwood sandwich has 5 slices.
Combining these terms we get [tex]3n + 4n + 5[/tex]. Combining like terms gets us the expression [tex]7n + 5[/tex].
To solve for [tex]7n + 5[/tex], we have to make it an equation. Using the information in Part B, the Deli ends up receiving 110 slices of bread. So, the equation is
[tex]7n + 5=110[/tex]
We want to isolate n on one side, to do this we have to subtract 5 then divide by 7.
[tex]7n + 5 - 5= 110-5\\\\7n = 105\\\\7n\div7 = 105\div7\\\\n = 15[/tex]
So 15 people are going to the picnic.

Wakaba buys some granola bars at $0.50 each and energy drinks at $2 each for a group hike. She buys twice as many granola bars as energy drinks. If she spends $27 in total, how many granola bars and energy drinks does she buy?
Answers
Answer: 9 energy drinks and 18 granola bars.
Step-by-step explanation:
Price per granola bar = $0.50
Price per energy drink = $2.
We can define G as the number of granola bars that she bought, and D as the number of drinks that she bought.
Then
"She buys twice as many granola bars as energy drinks."
G = 2*D
" If she spends $27 in total"
G*$0.50 + D*$2 = $27
So we have a system of equations:
G = 2*D
G*$0.50 + D*$2 = $27
The first step will be to replace the first equation into the second one, and solve it for D.
(2D)*$0.50 + D*$2 = $27
D*(2*$0.50) + D*$2 = $27
D*$1 + D*$2 = $27
D*$3 = $27
D = $27/$3 = 9.
So she bought 9 energy drinks, and we know that:
G = 2*D
G = 2*9 = 18
She bought 18 granola bars.

Answers
Answer:
D) systematic
Step-by-step explanation:
Systematic sampling. With systematic random sampling, one creates a list of every member of the population, and from the list, one can randomly select the first sample element from the first Nth elements on the population list. Thereafter, we select every Nth element on the list. Selection is done according to a random starting point but with a fixed, periodic interval. This interval, which is called the sampling interval, is calculated by dividing the population size by the desired sample size.
