divide this polynomial:
(x^2-6x-20) divided by (x+2)
* if someone would be able to tell me how to divide this it would be very MUCH appreciated
Answers
So I'll show you how to divide the polynomial step-by-step
First you want to write this out like any long division problem.
After that you need to see what times x is x^2?
x*x is x^2 so you want to write x over -6x, you have to make sure that you write it over the same degree term.
Now you multiply both x and 2 (which came from the x +2) by x (which was what you wrote in your first part of the quotient)
Then you subtract what you got from multiplying the x and 2 by x (you should have gotten -8x)
Now you want to bring down the next term in the dividend.
So you want to see what times x is -8x? (This should be -8)
Now you write -8 in the quotient. Now your quotient should be x-8.
After that, you want to multiply x+2 by the -8 and subtract again. (you should get -4)
Since you've filled in the last space in your quotient you have a remainder of -4. Remember to write the remainder as a fraction, -4/x+2

Consider the function y = x^2 − 18x. Enter the values for the variables to complete the inverse
Answers
Given the equation:
y = x^2 – 18x
Rewrite in vertex form:
y = x^2 – 18x + (18/2)^2 – (18/2)^2
y = (x – 9)^2 – 81
Swap x and y:
x = (y – 9)^2 – 81
Solve for y:
x + 81 = (y – 9)^2
y – 9 = sqrt (x + 81)
y = sqrt (x + 81) + 9
or
y = (x + 81)^(1/2) + 9
Can you find the missing angle measurements
Answers
if you notice the tickmarks on those sides, that means they're equal, that means is an isosceles triangle, or with two equal sides, so the 70° angle is the vertex angle, and the other two angles are just two twins, 180 - 70 = 110, split that equally to the twins, and you get that, check the picture.
what's is "x"? well, "x" is just a supplementary angle of the one inside the triangle, thus 180 - 55.

A color printer prints 9 pages in 3 minutes. how many minutes does it take per page
Answers
3 pages per min
3/60 seconds = .05 seconds
.05 s/ 60 = 0.00083333 min per pg.
Final answer:
To calculate time per page, divide the total printing time by the number of pages. A printer that prints 9 pages in 3 minutes takes approximately 0.333 minutes (or 20 seconds) to print one page.
Explanation:
The question is asking us to calculate the time it takes for a color printer to print one single page. To find this, we need to divide the total time taken to print multiple pages by the number of pages printed. So, if a printer prints 9 pages in 3 minutes, we can calculate the time per page as follows:
First, identify the total time taken for printing multiple pages, which is 3 minutes for 9 pages.
Divide the total minutes by the number of pages to get the time per page. In this instance, it would be 3 minutes ÷ 9 pages.
Perform the division to find the time it takes to print one page. 3 minutes ÷ 9 pages = 0.333... minutes per page.
Therefore, it takes approximately 0.333 minutes (or 20 seconds) for the color printer to print one page.

Why does dividing by a fraction make a number bigger?
Answers
What does it mean to divide 2 by 1/2? What we're asking is, in essence, the inverse of a multiplication problem: 1/2 times what number gets us 2? Or, if we split 2 up into pieces 1/2 in size, how many pieces would make up the whole? Well, 1/2 + 1/2 + 1/2 + 1/2 = 2, which means we need four halves to make the whole (2). Similarly, if you divided 3 by 1/3, it would take 9 thirds to make three, so 3/(1/3) = 9.
It also helps to consider the fact that any number divided by 1 simply gives you back that number, and any number divided by a number greater than one produces a number less than the one you started with (i.e. 6/2 = 3, which is less than 6), so it would make sense if dividing by a number between 1 and 0 gave you back a number greater than the one you started with.
A number dividing by a proper fraction always make the number bigger.
What is Fraction?Fractions are a kind of real numbers where we express a number as a part of a whole.
Fractions are of the form p/q, where p is called the numerator and q is called the denominator.
Algebraically speaking when a number is divided by a fraction, then actually the number is getting multiplied by it's reciprocal.
For example [tex]\frac{5}{1/2}[/tex] = 5 × [tex]\frac{2}{1}[/tex] = 10
That is a number when get divided by a proper fraction, operation is changed into the multiplication of the reciprocal.
In other words, we have to find that 5 is divided into how many equal 1/2
parts or 0.5 equal parts. Now, 1/2 part is actually the half part of 1.
Since 1/2 is half part of 1, 1 can be divided into 2 equal 1/2 parts.
We know that 5 when divided into equal 1 parts, we will get 5 parts.
So 5 can be divided into 5 × 2 = 10 equal 1/2 parts.
Hence, dividing by a fraction make a number bigger.

Dimitri is paid 8 percent commission on his total sales every pay period. Last pay period, he sold $6,300 worth of items. After a state tax of 6 percent is deducted from his commission, how much is left to the nearest dollar?
Answers
Answer:

Given,
The amount at which the items are sold = $ 6,300,
Also, commission percentage = 8 %,
Thus, commission = 8% of 6300
[tex]=\frac{8\times 6300}{100}[/tex]
[tex]=\frac{50400}{100}[/tex]
[tex]=\$ 504[/tex]
Now, deducted tax percentage on commission = 6%,
Hence, the left amount of commission = commission - 6% of the commission

A pilot flies 640 miles with a tail wind of 35 miles per hour. Against the wind, he flies only 455 miles in the same amount of time. Find the rate of the plain in still air
Answers
so, we know the wind rate is 35mph.
when the pilot goes with it, it runs for say "t" hours and covers 640 miles.
when he goes against it, it runs for say also "t" hours, covering 455 miles only.
now, let's say the still air speed of the plane is "r", so when it goes with the wind, is not really going "r" mph, is really going "r + 35", because the wind is adding speed.
likewise, when it goes against it, the speed is not "r" but "r - 35", the wind is slowing it down.
[tex]\bf \begin{array}{lcccll} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{t}\\ &------&------&------\\ \textit{with wind}&640&r+35&t\\ \textit{against the wind}&455&r-35&t \end{array} \\\\\\ \begin{cases} 640=t(r+35)\implies \cfrac{640}{r+35}=\boxed{t}\\\\ 455=t(r-35)\\ ----------\\ 455=\left( \boxed{\frac{640}{r+35}} \right)(r-35) \end{cases}[/tex]
[tex]\bf 455(r+35)=640(r-35)\implies 455r+15925=640r-22400 \\\\\\ 38325=185r\implies \cfrac{38325}{185}=r\implies \cfrac{7665}{37}=r\implies 207\frac{6}{37}=r[/tex]

If m∠TRK equal 32.5°, what is m∠TSK?
Answers
The measure of angle TSK is 130°, because it is an inscribed angle that intercepts the same arc as angle TRK, and angle TRK is half the measure of the central angle that intercepts the same arc.
The correct answer is option C.
The center of the circle is S, and the measure of angle TRK is 32.5°. We want to find the measure of angle TSK.
We can use the following theorem to solve this problem:
Inscribed Angle Theorem: An inscribed angle is half the measure of the central angle that intercepts the same arc.
In other words, if an angle is inscribed in a circle and intercepts a certain arc, then the measure of that angle is half the measure of the central angle that intercepts the same arc.
In this problem, angle TRK is an inscribed angle that intercepts arc KT. Therefore, the measure of angle TRK is half the measure of the central angle that intercepts arc KT.
Let's call the central angle that intercepts arc KT θ. Since angle TRK measures 32.5°, we know that θ measures 32.5° * 2 = 65°.
Now, we can use the Inscribed Angle Theorem again to find the measure of angle TSK.
Angle TSK is an inscribed angle that intercepts arc KT, and the measure of the central angle that intercepts arc KT is 65°. Therefore, the measure of angle TSK is half the measure of the central angle that intercepts the same arc, which is 65° * 2 = 130°.
The measure of angle TSK is 130° making option C the correct option.

Answers
The x-intercept for the equation 2y - 5x = 30 is found when y is set to zero and the equation is solved, resulting in the x-intercept being -6.
Explanation:To find the x-intercept of a given equation, you need to set y equal to zero and solve for x. So, for the equation 2y - 5x = 30, you set y = 0 which leads to the adjusted equation of -5x = 30
To isolate x, you should divide both sides of the equation by -5, which gives x = -6. Therefore, the x-intercept of the equation 2y - 5x = 30 is -6.

Answers
x - 4 = 7 (add 4 to both sides to get x by itself)
x = 11 (one of the answers)
x - 4 = -7
x = -3 (other answer)
So the answer is { -3, 11 }
-----------------------------------------
Checking choice A
Plug in x = -3
|x-4| = 7
|-3-4| = 7 ... replace x with -3
|-7| = 7
7 = 7
We have a true equation so x = -3 works
--------------
Plug in x = 3
|x-4| = 7
|3-4| = 7 ... replace x with 3
|-1| = 7
1 = 7
The last equation is false so x = 3 is not a solution. We can cross choice A off the list.
-----------------------------------------
Checking choice B
We already checked x = -3 (see above in choice A). All we need to do is check x = 11
|x-4| = 7
|11-4| = 7 .... replace x with 11
|7| = 7
7 = 7
We have a true equation so x = 11 works
Since x = -3 and x = 11 work, this means we have the proper solution set {-3, 11}. So this means choice B is the final answer
-----------------------------------------
For the sake of completeness, let's check choice C.
Plug in x = -11
|x-4| = 7
|-11-4| = 7 ... replace x with -11
|-15| = 7
15 = 7
The last equation is false so choice C can be ruled out as well.
-----------------------------------------
We can cross choice D off the list since we found there is a solution set and it is {-3, 11} back in choice B.
-----------------------------------------
Let's say that we didn't have these answer choices and it was a fill in the blank type of problem. Here's how to find the two solutions
|x-4|=7
x-4=7 or x-4=-7 ...... break up the absolute value
x-4+4=7+4 or x-4+4=-7+4 .... add 4 to each side (for each equation)
x = 11 or x = -3
x = -3 or x = 11
So the solution set is {-3, 11}
