How to solve x3 6x2 11x 6 0?

Answers

Answer 1

The solutions of the cubic equation x³ + 6x² + 11x + 6 = 0 will be -1, -2, and -3.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The equation is given below.

x³ + 6x² + 11x + 6 = 0

Factorize the equation, then we have

x³ + 6x² + 11x + 6 = 0

x³ + x² + 5x² + 5x + 6x + 6 = 0

x²(x + 1) + 5x(x + 1) + 6(x + 1) = 0

(x + 1)(x² + 5x + 6) = 0

(x + 1)[x² + 3x + 2x + 6] = 0

(x + 1)(x + 3)(x + 2) = 0

x = -1, -2, -3

The solutions of the cubic equation x³ + 6x² + 11x + 6 = 0 will be -1, -2, and -3.

20, because by using Pythagorean theorem, a2+b2=c2. Let’s make a=12 and b=16. (12)2 + (16)2 =c2. If you simplify this, 144 + 256 = c2. 144 + 256 = 400, so 400=c2. Finally if we take the square root of both sides, c=20.

When looking for a job micah is told that the monthly salary has a range of 876 he also knows that the starting salary is 1,793 per month what is the maximum amount of money that micah can earn in this position?

Answers

Answer:

2669

Step-by-step explanation:

Given that :

Salary range = 876

Starting salary = 1793 monthly

The starting salary represents the minimum amount Micah can earn monthly

Therefore, the amount of money much can earn can be calculated thus :

Recall :

Range = maximum - minimum

876 = maximum - 1793

876 + 1793 = maximum

Maximum = 2669

Hence, the maximum salary Micha can earn is 2669 monthly

find the inverse of h(x)= -x^5+2 step by step

Answers

Hi there!

[tex]\large\boxed{y = \sqrt[5]{-(x-2)}}[/tex]

[tex]h(x) = -x^{5} + 2[/tex]

Rewrite h(x) as y:

[tex]y = -x^5 + 2[/tex]

Switch the x and y variables:

[tex]x = -y^{5} + 2[/tex]

Isolate y by subtracting 2 from both sides:

[tex]x - 2 = -y^5[/tex]

Multiply both sides by -1:

[tex]-(x-2) = y^5[/tex]

Take the 5th root of both sides:

[tex]y = \sqrt[5]{-(x-2)}[/tex]

Therefore the two middle obs are 30,36

Therefore median 30+36/2

Therefore median 66/2

Therefore median is 33

There is no mode in the following obs

If you are helped with my answer pls tag me brianliest I really want it

THANK YOU.......

The median of the numbers is M = 33 and the mode is not defined

What is Median?

The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points

Arrange the data points from smallest to largest.

If the number of data points is odd, the median is the middle data point in the list.

If the number of data points is even, the median is the average of the two middle data points in the list.

Given data ,

Let the set of numbers be represented as set A

Now , the value of A is

A = { 40, 28, 24, 37, 43, 26, 30, 36 }

Arranging the numbers in the ascending order , we get

A = { 24 , 26 , 28 , 30 , 36 , 37 , 40 , 43 }

Now , the total number of elements in the set A = 8

So , the median is the average of the two middle data points in the list.

M = ( 30 + 36 ) / 2

M = 33

The mode of the numbers is the numbers that appears the most often

So , mode is not defined

Hence , the median is M = 33

Answers

Answer:

y= 0.007x- 4.945

The estimated average miles per gallon for cars of this weight is (20.829 or 21 ) miles per gallon.

The miles per gallon of this car below (18 < 20.829) the average for cars of this weight.

Step-by-step explanation:

Weight                   Miles

2687                        24                   64,488

3522                        18                     63,396

3827                        16                      61,232

∑y²=4075; ∑y=199;    ∑x²= 116,406,174 ; ∑x=33,844 ;  ∑xy=659,808

b= n∑XY - (∑X)(∑Y)/ n∑X² - (∑X)²

b=(10) (659,808) - (33,844)(199)/ 10 (116,406,174) - 1,145,416,336

b=6,598,080- 6,734,956/ 1,164,061,740 -1,145,416,336

b=136,876/18,645,404

b= 0.007341

a= Y`- bX`

a= 19.9- (0.007341) (3384.4)

a= 19.9 -24.845

a=-4.945

Y^= -4.945+ ( 0.007341) X

y= 0.007x- 4.945

Putting the values

y= 0.007x- 4.945

18 = 0.007(3511) - 4.945

18< 20.829

​The estimated average miles per gallon for cars of this weight is (20.829 or 21 ) miles per gallon.

The miles per gallon of this car below (18 < 20.829) the average for cars of this weight.

What does the constant term in the above expression represent? A. The constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold. B. The constant -10 represents the maximum number of cheeseburgers sold by the food stall at the funfair. C. The constant -10 represents the total money earned by setting up the food stall. D. The constant -10 represents the cost of each cheeseburger at the food stall.

Answers

Answer:

In the expression [tex]\dfrac{60 \cdot x}{x + 3} -10[/tex] what the constant term -10 represents is;

A. The constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold

Step-by-step explanation:

Whereby the expression is as given in a similar question which is presented as follows;

[tex]\dfrac{60 \cdot x}{x + 3} -10[/tex]

Where the expression represents the total money earned when a food stall is set up at a fair where 'x' stands for the number of cheeseburgers sold

Then when no cheeseburger were sold, x = 0, such at the start just after setting up the food stall,  we then have;

[tex]\dfrac{60 \times 0}{0 + 3} -10 = -10[/tex]

Therefore, the money earned at the start = -10

∴ The money spent at the start = 10

Therefore, the constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold.
