Answer:

m = - 1 , m = 0 , m = \(\frac{7}{2}\)

Step-by-step explanation:

2m³ - 5m² - 7m = 0 ← factor out common factor m from each term

m(2m² - 5m - 7) = 0

factorise the quadratic 2m² - 5m - 7

consider the factors of the product of the coefficient of the m² term and the constant term which sum to give the coefficient of the m- term

product = 2 × - 7 = - 14 and sum = - 5

the factors are + 2 and - 7

use these factors to split the m- term

2m² + 2m - 7m - 7 ( factor the first/second and third/fourth terms )

2m(m + 1) - 7(m + 1) ← factor out (m + 1) from each term

(m + 1)(2m - 7)

then

2m³ - 5m² - 7m = 0

m(m + 1)(2m - 7) = 0 ← in factored form

equate each factor to zero and solve for m

m = 0

m + 1 = 0 ( subtract 1 from both sides )

m = - 1

2m - 7 = 0 ( add 7 to both sides )

2m = 7 ( divide both sides by 2 )

m = \(\frac{7}{2}\)

solutions are m = - 1 , m = 0 , m = \(\frac{7}{2}\)

The polynomial 18x³ - 2x² + 4x - 1 consists of four terms.

The number of terms in a polynomial helps when performing operations like simplification, factoring, or evaluating expressions.

The polynomial 18x³ - 2x² + 4x - 1 consists of four terms.

In order to determine the number of terms in a polynomial, we count the number of distinct algebraic expressions separated by addition or subtraction operations.

In this polynomial, we have:

Term 1: 18x³ (This is the term with the highest degree, which is 3 in this case, and it includes the coefficient 18.)

Term 2: -2x² (This term has a degree of 2 and a coefficient of -2.)

Term 3: 4x (This term has a degree of 1 and a coefficient of 4.)

Term 4: -1 (This is a constant term with a degree of 0.)

We can see that there are four distinct terms separated by addition and subtraction operations:

18x³, -2x², 4x, and -1.

Answer: 75% of the rate lies in 47 per month and 55 per month.

Step-by-step explanation:

The mean rate for a satellite television from a sample of households was $51.00 per month,  with a standard deviation of $2.00 per month.

According to the Chebychev's Theorem, atleast \((1-\dfrac{1}{k^2})\)  % of the data lies within k standard deviation from the mean.

For k=2

\(1-\dfrac1{2^2}=1-\dfrac14=\dfrac34=0.75\ or \ 75\%\)

Alteast 75% of data lies within 2 standard deviation from mean.

i.e. 51-2(2) per month and 51+2(2) per month

i.e. 47 per month and 55 per month

Hence, 75% of the rate lies in 47 per month and 55 per month.

The equation of the line that passes through the point (4, 2) with a slope of -2 is y = -2x + 10.

A straight line's general equation is y = mx plus c, where m denotes the line's slope and c its y-intercept. It is the geometry-related straight line solution that is used the most frequently. A straight line's equation can be expressed in various ways, including point-slope form, slope-intercept form, intercept form, standard form, etc. A straight line is a two-dimensional geometric object that can reach infinity on both sides.

The equation of a line can be represented in the slope-intercept form, which is given by:

y = mx + b

where:

m = slope of the line

b = y-intercept of the line

Given:

Point (x1, y1) = (4, 2)

Slope (m) = -2

Plugging in the given values into the slope-intercept form, we have:

y = -2x + b

Now, we can use the given point (4, 2) to solve for the y-intercept (b). We substitute the coordinates of the point (x1, y1) into the equation and solve for b:

2 = -2(4) + b

2 = -8 + b

b = 2 + 8

b = 10

So, the value of b is 10.

Putting the values of m and b back into the slope-intercept form, we get the equation of the line:

y = -2x + 10

So, the equation of the line that passes through the point (4, 2) with a slope of -2 is y = -2x + 10.

Step-by-step explanation:

In normal distribution(z) tomato plants have a height of less than 2.58 feet is 1.017%.

The normal distribution is a "continuous probability distribution that its symmetrical around its mean with most values near the central peak".

According to the question,

The heights of tomato plants are Normally distributed.

Mean(μ) = 3.56

Standard deviation (σ)  = 0.25

For a tomato plant that has a height of 2.98 feet

In order to find the Percentage of tomato plantof s have a height less than 2.98 feet

Standard Normal Distribution Formula,

z = (x-μ)/σ    where X~(μ,σ).

( 2.98 - 3.56 ) / 0.25  =-0.58 / 0.25  = -2.32.

P ( x < 2.58 ) = P( z < -2.32 )

                     = 0.01017( Using standard Normal distribution table)

Find the percentage of tomato plants with have a height of fewer than 2.58 feet is

Multiply 0.01017 by 100

= 0.01017 x 100 %

= 1.017%

Hence, using Standard Normal distribution we find tomato plants have heights less than 2.58 feet is 1.017%

The correct answers are option 1, Option 3 and option 4 which are:-

2(x² + 6x + 9) = 3 + 18

2(x² + 6x) = 3

x+3 = ±√21/√2

The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.

We will check all three options one by one:-

2(x² + 6x + 9) = 3 + 18

2x² +  12x + 18 = 3 + 18

2x² + 12x -3 = 0

We are getting the original equation so it is correct.

2(x² + 6x) = 3

2x² + 12x = 3

2x² + 12x - 3 = 0

This is also right.

x+3 = ±√21/√2

Squaring on both the sides:-

( x + 3 )² = 21 / 2

x² + 6x + 9 = 21 / 2

2x² + 12x + 18 = 21

2x² + 12x = 21 - 18

2x² + 12x -3 = 0

This is also right

Therefore the correct answers are option 1, Option 3 and option 4 which are:-

2(x² + 6x + 9) = 3 + 18

2(x² + 6x) = 3

x+3 = ±√21/√2

The average price of the textbook over all seasons is $77.9625 (without the dollar sign).

What is Average?

When you add two or more numbers and divide the result by the number of numbers you added together, you get an average.

To compute the average price of the textbook over all seasons, we need to calculate the weighted average of the prices during each season, where the weights are the proportions of sales in each season.

Let P1, P2, and P3 be the average prices of the textbook during the "end of term," "start of term," and "other" periods, respectively. Let w1, w2, and w3 be the corresponding proportions of sales in each period, as given in the table. Then the weighted average price is:

Average price = w1P1 + w2P2 + w3*P3

Substituting the values from the table, we get:

Average price = 0.3076.75 + 0.4582.52 + 0.25*71.21

= 23.025 + 37.134 + 17.8025

= 77.9625

Hello!

We have all angles of the triangle:

We will use the law of cosines. This relation is valid for all sides of any t

We have:

angle A = 12°

côté a = 10

angle B = 150°

This is therefore the first case of application of the sine law.

So:

\(\sf \dfrac{b}{sin~B} = \dfrac{a}{sin~A}\)

\(\sf b =\dfrac{sin~B~*~a}{sin~A} = \dfrac{sin~150~*~10cm}{sin~12} = \dfrac{arcsin~0.5~*~10cm}{arcsin~0.2079116908} = \dfrac{30~*~10cm}{12} = \dfrac{300cm}{12} = \boxed{\sf25cm}\)

When applying the some rule, we only combine two equal ratios at once. Consequently, we deal with pairs of sides and angles that have equivalent ratios.

When two ratios are equal, a percentage is formed; alternatively, two equal ratios can be said to produce a proportion. When we understand that two ratios are equal, you can write a proportion. The ratios of these two numbers are equal.

When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant. Two angles are said to be complimentary if their sum is 90 degrees. Alternatively put, two angles are said to be complimentary if they combine to make a right angle.
