Answer:

The value of x = - 1 and 2 double root of this function

Step-by-step explanation:

we need to find the value of x which double root of f(x)=x^{3} -3x-2

If we replace x with -2 then

f(-2)=(-2)^{3} -3(-2)-2 = -8+6-2 =-4

If we replace x with -1 then

f(-1)=(-1)^{3} -3(-1)-2 = -1+3-2 =0

If we replace x with 1 then

f(1)=(1)^{3} -3(1)-2 = 1-3-2 =-4

If we replace x with 2 then

f(2)=(2)^{3} -3(2)-2 = 8-6-2 =0

Hence, the value of x = - 1 and 2 double root of this function

Answer: \mu_x=18\text{ hours}

\sigma_x=4\text{ hours}

Step-by-step explanation:

We know that mean and standard deviation of sampling distribution is given by :-

\mu_x=\mu

\sigma_x=\dfrac{\sigma}{\sqrt{n}}

, where \mu = population mean

\sigma =Population standard deviation.

n= sample size .

In the given situation, we have

\mu=18\text{ hours}

\sigma=6\text{ hours}

n= 2

Then, the expected mean and the standard deviation of the sampling distribution will be :_

\mu_x=\mu=18\text{ hours}

\sigma_x=\dfrac{\sigma}{\sqrt{n}}=\dfrac{6}{\sqrt{2}}=4.24264068712\approx4  [Rounded to the nearest whole number]

Hence, the the expected mean and the standard deviation of the sampling distribution :

\mu_x=18\text{ hours}

\sigma_x=4\text{ hours}

<span>we have to solve simultaneous equations.
                                                                     
x = 10 oz. boxes
                                                                     
y = 16 oz. boxes
                                                                               
simultaneous equations
                                                                     
x + y = 24 ---1)
                                                                     
3.50x + 5.00y = 97.50 ----2)
                                                                   
to solve for x we need to eliminate y, therefore we have to multiply 1st equation by 5
                                                                   
5x + 5y = 120 --3)
                                                                   
subtract 3) - 2)
                                                                   
5x - 3.50x = 120 - 97.50
                                                                   
1.50x = 22.5 x = 15

What is the factored form of the binomial expansion 125x^3 + 525x^2 + 735x + 343?
yarga [219]

Answer:

Step-by-step explanation:

1. regroup terms

125x^3+343+525x^2+735x

2. Rewrite 125x^3 as  (5x)^3 and 343 as 7^3

(5x)^3+7^3+525x^2+735x

3. Since both terms are perfect cubes, factor using the sum of cubes formula, a^3+b^3 = (a+b)(a^2-ab+b^2), where a=5x and b=7

(5x+7)((5x)^2-(7)(5x)+(7)^2)+525x^2+735x

(5x+7)(25x^2-35x+49)+525x^2+735x

4. Factor 105x out of 525x^2+735x

(5x+7)(25x^2-35x+49)+105x(5x+7)

5. Regroup

(5x+7)(25x^2-35x+49+105x)

(5x+7)(25x^2+70x+49)

6. Factor again

(5x+7)(5x+7)^2

(5x+7)^3
