Answer:

5x (3-2x^2)

Step-by-step explanation:

so all you have to do is 15x-10x=5x right?, then all you have to do is 15/5=3. 10x/5x=2x. then subtract 1 from the exponents. then you get the answer. okay Im sure about the fist part and the divison but not the exponents, I did use a calculator to check it though.

The factorize equation is, [tex]\rm 5x (\sqrt{3} - \sqrt{2}x) (\sqrt{3}+\sqrt{2}x}) = 0[/tex].

The roots of the equation are [tex]0 , \ \dfrac{\sqrt{3}}{\sqrt{2} }, \dfrac{-\sqrt{3}}{\sqrt{2} }[/tex].

Given that,

Equation; [tex]\rm 15x - 10x^3[/tex]

We have to determine,

Factorize the equation and factor of the equation.

According to the question,

To factorize the equation and determine the factor of the equation following all the steps given below.

Equation; [tex]\rm 15x - 10x^3[/tex]

                   [tex]\rm = 15x - 10x^3 = 0 \\\\= 5x (3-2x^2) = 0[/tex]

                   [tex]\rm = 5x (3-2x^2) = 0\\\\ = 5x (\sqrt{3} - \sqrt{2x}) (\sqrt{3}+\sqrt{2x}) = 0[/tex]

                    [tex]\rm = 5x (\sqrt{3} - \sqrt{2}x) (\sqrt{3}+\sqrt{2}x}) = 0\\\\ The \ roots \ of \ the \ equation \ are;\\\\5x = 0, \ x = \dfrac{0}{5}, \ x =0\\\\\\[/tex]

                    [tex]\sqrt{3} - \sqrt{2x} = 0, \sqrt{2}x = \sqrt{3}, \ x = \dfrac{\sqrt{3} }{\sqrt{2} }\\\\ \sqrt{3} +\sqrt{2x} = 0, \sqrt{2}x = -\sqrt{3}, \ x =- \dfrac{\sqrt{3} }{\sqrt{2} }[/tex]

Hence, The roots of the equation are [tex]0 , \ \dfrac{\sqrt{3}}{\sqrt{2} }, \dfrac{-\sqrt{3}}{\sqrt{2} }[/tex].

Answer:

The volume of the new tent will be 3/2 times the volume of the original

Step-by-step explanation:

The original tent is a triangular prism, which missing dimensions of the tent are:

Volume of the original tent:

V = 1/2*b*h*l

The only difference between the new and the original tent are their heights. Let's call h' = 6 ft to the height of the new tent.

Volume of the new tent:

V' = 1/2*b*h'*l

Dividing V' by V:

V'/V = (1/2*b*h'*l)/(1/2*b*h*l)

V'/V =h'/h

Replacing with data:

V'/V =6/4

V' = 3/2*V

Answer:

any number except -20

Step-by-step explanation:

[tex]|-k-2|<18[/tex]

[tex]-k-2<18[/tex]                              [tex]-k-2>18[/tex]

[tex]-k<18+2[/tex]                               [tex]-k>18+2[/tex]

[tex]-k<20[/tex]                                      [tex]-k>20[/tex]

Multiply by -1 to make the k positive. This will alter all the terms which means 20 will become negative. NOTE: When multiplying or dividing by negative numbers, the inequaliy sign flips.

[tex]k>-20[/tex]                                           [tex]k<-20[/tex]

k must be either greater than -20 but not including it or fewer than -20 but not including it; therefore, any number between negative infinity and -21 and -19 and postive infinity

Step-by-step explanation:

In the circle below DAB and DCB are right angles and BDC=29. The figure is not drawn to scale. What is CAD?

A) 156  this is most likely correct

B)204  This one may be correct

C)238  X

D)282  X

hope

Based on the calculations, the measure of angle CAD is equal to: C. 238°.

A right angle can be defined as a type of angle that is formed by the intersection of two (2) straight lines at 90 degrees. Thus, a right angle has a measure of 90 degrees.

Angle DBC = 90 - Angle BDC

Angle DBC = 90 - 29

Angle DBC = 61°.

Angle DC = 2 × (Angle DBC)

Angle DC = 2 × 61

Angle DC = 122°.

Now, we can determine the measure of angle CAD:

Angle CAD = 360 - Angle DC

Angle CAD = 360 - 122

Angle CAD = 238°.

2/7, 7/13, 5/9, 10/11

Step-by-step explanation:

I used benchmark fractions to determine the order of the fractions above. 2/7 is close to 0, so it is first. 7/13 is close to 1/2, but is less than 5/9, so it is second. 5/9 is also close to 1/2, but it is greater than 7/13, so it is third. 10/11 is close to 1, so it is last.

Answer:

for diamond or spade: 1/2= 0.5 = 50%

Step-by-step explanation:

13/52 = 1/4 to diamond, heart, club or spade

1/4= 0.25

0.25*100% = 25%

If we need to choose diamond or spade,

1/4 for diamond, 1/4 for spade

diamond or spade:   1/4+ 1/4=1/2

1/2 = 0.5 = 50%

Answer:

2/4

0.50

50%

Step-by-step explanation:

If its a diamond or spade then it is it is basically written as 2/4 since there is 4 suits and your trying to pull 2 out of the four. 50% converts to 2/4 and you can turn 50% to decimal by putting a decimal point and a 0 to get 0.50

Left group: [tex]2x^{5\\}[/tex]     Right group: 3

Step-by-step explanation:

Right group: 3.x - 21 = 3.x - 3.7 = 3 . ( x - 7 )

21 is equal 3 times 7. When we do this change, it is clear which is the common factor, which is just the number 3.

Left group: 2[tex]x^{6\\}[/tex] + 14[tex]x^{5\\} \\[/tex]  =  2[tex]x^{5\\}[/tex].x + 2[tex]x^{5}[/tex].7 = 2[tex]x^{5\\}[/tex] . (x + 7)

Explanation: From the first term we can take 2[tex]x^{5\\}[/tex] and an x is the rest. From the second term we take 2[tex]x^{5\\}[/tex] either, but here the rest is 14. That's the reason the common factor is 2[tex]x^{5\\}[/tex].

A = 15 yd^2

Step-by-step explanation:

The area of a triangle

A = 1/2 bh where b is the base length and h is the height

A =1/2 (10) * 3

A = 15 yd^2

Multiply the base by the height and divide by 2. So 10x3 is 30 and 30 divided by 2 is 15.

Answer:

1. The error in the assumption is taking the sample mean, [tex]\bar x[/tex], as being equal to the population mean, μ

2. To correct the error, the manager will need to generate the confidence interval based on the population standard deviation on the acceptable values of the mean using the following relation;

[tex]CI=\bar{x}\pm z\frac{\sigma}{\sqrt{n}}[/tex]

Step-by-step explanation:

We note that from the central limit theorem as the size of the sample, n, becomes more and more larger, the mean of the sample, [tex]\bar x[/tex], approaches that of the population mean, μ, therefore as the grocery store manager uses the sample mean as the population mean's point estimate an error will be observed based on the size of the sample compared to the population, where the difference between the two means (the population mean and the sample mean) is [tex]\left | \bar{x} - \mu \right |[/tex]

1. The error in the assumption is taking the sample mean, [tex]\bar x[/tex], as being equal to the population mean, μ

2. To correct the error, the manager will need to generate the confidence interval based on the population standard deviation on the acceptable values of the mean using the following relation;

[tex]CI=\bar{x}\pm z\frac{\sigma}{\sqrt{n}}[/tex]

Where:

σ = Population standard deviation = $30

z = z value at 95% confidence level = 1.96

[tex]\bar x[/tex] = Sample mean $160

n = Sample size = 10

Plugging in the values, we have;

$141.4 < [tex]\bar x[/tex] < $178.6

Hence the expected value of the mean should be between $141.4 and $178.6.

You can use the FOIL method (First, Outer, Inner Last) as how most people prefer it.

Answer:

2

Step-by-step explanation:

The equation is p = 8/v.

If p = 4, then p = 4 = 8/v

Inverting both sides, we get  

                           1/4 = v/8

Multiplying both sides by 8, we get:

                              2 = v

If the value of p is 4, then the value of V will be 2. Then the correct option is C.

The solution of the equation means the value of the unknown or variable.

The equation is given below.

p = 8/V

If the value of p is 4, then the value of V will be

4 = 8 / V

V = 8 / 4

V = 2

Then the correct option is C.
