Which polynomial is equal to  (-3x^2 + 2x - 3) subtracted from  (x^3 - x^2 + 3x)?

The polynomial equal to (-3x^2 + 2x - 3) subtracted from  (x^3 - x^2 + 3x) is [tex]x^3 + 2x^2 + x + 3[/tex]

Given that two polynomials are: [tex](-3x^2 + 2x - 3)[/tex] and [tex](x^3 - x^2 + 3x)[/tex]

We have to find the result when [tex](-3x^2 + 2x - 3)[/tex] is subtracted from  [tex](x^3 - x^2 + 3x)[/tex]

In basic arithmetic operations,

when "a" is subtracted from "b" , the result is b - a

Similarly,

When [tex](-3x^2 + 2x - 3)[/tex] is subtracted from  [tex](x^3 - x^2 + 3x)[/tex] , the result is:

[tex]\rightarrow (x^3 - x^2 + 3x) - (-3x^2 + 2x - 3)[/tex]

Let us solve the above expression

There are two simple rules to remember:

So the above expression becomes:

[tex]\rightarrow (x^3 - x^2 + 3x) + 3x^2 -2x + 3[/tex]

Removing the brackets we get,

[tex]\rightarrow x^3 - x^2 + 3x + 3x^2 -2x + 3[/tex]

Combining the like terms,

[tex]\rightarrow x^3 -x^2 + 3x^2 + 3x - 2x + 3[/tex]

[tex]\rightarrow x^3 + 2x^2 + x + 3[/tex]

Thus the resulting polynomial is found

WAR is given as 57 degrees.

If you draw a line from W to R, the angle WRA would also be 57 degrees.

57 + 57 = 114

The measure of AR = 180 -114 = 66 degrees.

Answer:

66.

Step-by-step explanation:

If You See W.And R., They Are The Same Angle's, So If They Are Little And Big At The Same Time, You Can Notice It Will Be 66* :)

Answer:

g(x) = - (x² + 3x + 2) = - x² - 3x - 2

Step-by-step explanation:

The graph represents the function f(x) = x² + 3x + 2.

Now, g(x) is the function which is obtained by reflecting f(x) across the x-axis.

While a graph of a function reflects across x-axis then its y-values will change sign for a fixed value of x.  

Therefore, the function g(x) will be given by  

g(x) = - (x² + 3x + 2) = - x² - 3x - 2 (Answer)

Answer:

[tex]Rs\ 4,296[/tex]

Step-by-step explanation:

step 1

Find out the lateral area of the pillars

we know that

The lateral area of a rectangular prism is equal to

[tex]LA=PH[/tex]

where

P is the perimeter of the base

H is the height of the prism

Determine the perimeter of the base

[tex]P=4(1)=4\ ft[/tex] ----> is a square base

[tex]H=6\ ft[/tex]

The lateral area is equal to

[tex]LA=4(6)=24\ ft^2[/tex]

Remember that the number of pillars is 2

so

[tex]LA=2(24)=48\ ft^2[/tex]

step 2

Find the cost of tiling the pillars at the rate of  Rs 52 per square feet

Multiply the lateral area of the two pillars by the rate

so

[tex]48(52)=Rs\ 4,296[/tex]

Answer:

length is 28 meters

width is 15 meters

Step-by-step explanation:

Write out formulas and assign variables:

Width: w

Length: l = 2w - 2

Here is a diagram:

            2w - 2              

|                                     |  w

|_________________|

The perimeter formula for rectangle is P = 2(l +w). Substitute the perimeter and the formula for length into the formula.

P = 2(l +w)

86 = 2(2w - 2 + w)       Simplify inside the brackets

86 = 2(3w - 2)            Divide both sides by 2

43 = 3w - 2              Add 2 to both sides

45 = 3w                  Divide both sides by 3

w = 45/3               Variable on left side is standard formatting

w = 15                 Width of basketball court

Substitute width into the length formula to fin length.

l = 2w - 2

l = 2(15) - 2

l = 30 - 2

l = 28           Length of basketball court

Therefore the length is 28 meters and the width is 15 meters.

The dimensions of the basketball court are 28 meters in length and 15 meters in width.

We need to find the dimensions of the rectangular court where the length (L) is 2 meters less than twice the width (W), given that the perimeter is 86 meters. We can set up the equations as follows:

First, substitute the value of L from the first equation into the second equation:

Simplify and solve for W:

Now, find the length (L):

Thus, the dimensions of the court are 28 meters in length and 15 meters in width.

Answer: x = 6

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is -3x.

Since 28 is being added to -3x, we subtract 28 from both sides of the equation to isolate the -3x. On the left, the +28 and -28 cancel out and on the right 10 - 28 is -18 so we have -3x = -18.

Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and we have x. On the right, -18 divided by -3 is 6 so we have x = 6 which is the solution to our equation.

Answer:

Step-by-step explanation:

x = small box and y = large box

30x + 40y = 330

y = 2x

30x + 40(2x) = 330

30x + 80x = 330

110x = 330

x = 330/110

x = 3 <===== 3 small boxes

y = 2x

y = 2(3)

y = 6 <=== 6 large boxes

check...

30x + 40y = 330

30(3) + 40(6) = 330

90 + 240 = 330

330 = 330 (correct)

The perimeter of rectangle is 16x-2y+4.

Step-by-step explanation:

Given dimensions are;

Length = 5x-y

Width = 3x+2

We know that;

Perimeter of rectangle = 2(Length + Width)

Perimeter of rectangle = [tex]2(5x-y+3x+2)[/tex]

Perimeter of rectangle = [tex]2(8x-y+2)[/tex]

Perimeter of rectangle = [tex]16x-2y+4[/tex]

The perimeter of rectangle is 16x-2y+4.

3000/8000 *100= 37.5%

Answer:

[tex]x=-2\sqrt5\ and\ x=2\sqrt5[/tex]

Step-by-step explanation:

Given:

The given equation to solve is:

[tex]x^2=20[/tex]

In order to solve the above equation, we take square root on both the sides.

While taking square root on both sides, we must consider both positive and negative values. So, this gives:

[tex]\sqrt{x^2}=\pm\sqrt{20}[/tex]

From the definition of square root function, we have

[tex]\sqrt{a^2}=a[/tex]

Therefore,

[tex]x=\pm\sqrt{20}[/tex]

Now, writing 20 into the product of its prime factors, we have

[tex]20=2^2\times 5[/tex]

Therefore, [tex]x=\pm\sqrt{2^2\times 5}[/tex]

We also know, [tex]\sqrt{a\times b}=\sqrt{a}\times\sqrt{b}[/tex]

So, [tex]\sqrt{2^2\times 5}=\sqrt{2^2}\times \sqrt{5}=2\sqrt5[/tex]

Therefore, [tex]x=\pm2\sqrt5[/tex]

So, there are two values of 'x'. They are:

[tex]x=-2\sqrt5\ and\ x=2\sqrt5[/tex]

Answer: 138

Step-by-step explanation:

Let the first number be x , the second number be x + 2 and the third number be x + 4 since they are consecutive even numbers.

Their sum implies:

x + x + 2 + x + 4 = 408

3x + 6 = 408

subtract 6 from both sides

3x + 6 - 6 = 408 - 6

3x = 402

divide through by 3

3x/3 = 402/3

Therefore x = 134.

The numbers are :

134 , 136 and 138 , this means that the largest number is 138

Answer:

The maximum rate of change is between second 15 and second 19.

Step-by-step explanation:

See the attached table.

The table shows the total distance a spider traveled after a light was turned on.

Now, the average rate of change between two consecutive times in the table is given by  

= [tex]\frac{\textrm {Total change in Distance in feet}}{\textrm {Total change in Time in seconds }}[/tex]

Therefore, between second 5 and second 11, the average rate of change = [tex]\frac{7 - 4}{11 - 5} = 0.5[/tex]

Between second 11 and second 15, the average rate of change = [tex]\frac{13 - 7}{15 - 11} = 1.5[/tex]

Between second 15 and second 19, the average rate of change = [tex]\frac{20 - 13}{19 - 15} = 1.75[/tex]

Between second 19 and second 28, the average rate of change = [tex]\frac{24 - 20}{28 - 19} = 0.44[/tex]

Therefore, the maximum rate of change is between second 15 and second 19. (Answer)

Sale Price = (100 - Discount Rate) x Cost Price

Let Y = Sale Price

By Putting the values in above equation:

Y = (100 - 45) x $650

Y = 0.55 x $650

Y = $357.5

Hence the Sale Price of the bicycle will be $357.5

Solution 4:

Percent error = [(Experimental Value - Accepted Value) / Accepted Value] x 100

Percent error = [(15.5 - 14.5) / 14.5] x 100

Percent error = [1 / 14.5] x 100

Percent error = 2.2%

Hence the percent error in Mark's estimate is 2.2%

Answer:

The value of x is 22.

Step-by-step explanation:

We are given that,

12 less triple the difference of x and 10 is 24.

So, according to question :

  3(x - 10) - 12 = 24

Adding '12' on both sides of the above equation, we get

  3(x -10) - 12 + 12 = 24 + 12

⇒3(x - 10) = 36

Dividing the above equation by '3', we get

  3(x - 10) ÷ 3 = 36 ÷ 3

⇒x - 10 = 12

Now, adding '10' on both sides of the above equation, we get

  x - 10 + 10 = 12 + 10

⇒x = 22

So, the value of x is 22.

In this question, we're trying to make an equation for the given scenario and answer a couple of leading questions.

We know that Aiko types at a rate of 70 words per minute

We would represent this as 70x

x = minutes

We are also given more information that he types 210 words in 3 minutes, that still follows our "70x" scenario.

So our equation would be:

y = 70x

The slope of the linear equation would be 70 or 70/1

The slope would be 70 because this is the change that's happening each minute.

A point on a graph would be at (1 , 70)

You would put this equation into a graph, and you would grab a point that's on the linear line. I'll insert a picture of the graph

The linear equation would be written as: y = 70x

The beginning point would be at 0, since Aiko doesn't type anything for 0 minutes.

Answer:

1 The slope of the linear equation is  70

2 One point on the graph of a linear equation will be 3, 210

3,This linear equation can be written as  y-210=70(x-3)

Explanation:

Suppose you know that:

[tex]\begin{array}{l}{\log 2 \approx 0.30103} \\{\log 3 \approx 0.47712}\end{array}[/tex]

Then note that:

[tex]43=\frac{129}{3} \approx \frac{128}{3}=\frac{2^{7}}{3}[/tex]

So

[tex]\log 43 \approx \log \left(\frac{2^{7}}{3}\right)=7 \log 2-\log 3 \approx 7 \cdot 0.30103-0.47712=1.63009[/tex]

We know that the error is approximately:

[tex]\log \left(\frac{129}{128}\right)=\log 1.0078125=\frac{\ln 1.0078125}{\ln 10} \approx 0.00782 .3=0.0034[/tex]
