Monomial has a degree of 4 in linear equation.

What in mathematics is a linear equation?

The algebraic equation y=mx+b is known as a linear equation. with m the slope and b the y-intercept as the single constant and a first-order (linear) term.

                       Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Let's define some of the vocabulary words so we can understand what is being asked.

trinomial: 3 terms   → each term is separated by a plus or minus sign

                              Example: 5x² + 3x + 2

monomial: 1 term   →  no plus or minus sign exists in the term.

                              Example: 5x²

degree: the largest exponent → it can be in any of the terms.

                              Example: 5x² has a degree of 2

It is possible that a monomial has an exponent greater than that of a trinomial so the answer is NO!

trinomial:   5x² + 3x + 2      has a degree of 2

monomial: 5x⁴                    has a degree of 4

Answer:

1/2

Step-by-step explanation:

Find the following limit:

lim_(x->∞) (x + 1)/(1 x + sqrt(x)^2 + 1)

(x + 1)/(1 x + sqrt(x)^2 + 1) = (x + 1)/(2 x + 1):

lim_(x->∞) (x + 1)/(2 x + 1)

The leading term in the denominator of (x + 1)/(2 x + 1) is x. Divide the numerator and denominator by this:

lim_(x->∞) (1 + 1/x)/(2 + 1/x)

The expressions 1/x and 1/x both tend to zero as x approaches ∞:

The 95% confidence interval for the variance in the pounds of impurities would be (3.829, 14.121).

In the given question, the quality-control manager of a chemical company randomly sampled twenty 100-pound bags of fertilizer to estimate the variance in the pounds of impurities.

The sample variance was found to be 6.62.

We have to find a 95% confidence interval for the population variance in the pounds of impurities.

From the question,

N=20,

s^2=6.62

So, the Standard Deviation(SD) = √s^2

SD = √6.62

SD = 2.573

The confidence interval for the population variance is given by the following formula:

[tex]\frac{(n-1)s^2}{ \chi_{\alpha/2}} \leq\sigma^2\leq \frac{(n-1)s^2}{ \chi_{1-\alpha/2}}[/tex]

On this case the sample variance is given and for the sample deviation is just the square root of the sample variance.

The next step would be calculating the critical values. First we need to calculate the degrees of freedom given by:

df = n-1

df = 20-1

df = 19

Since the Confidence is 0.95 or 95%, the value of α=0.05 and α/2=0.025, and we can use excel, a calculator or a table to find the critical values.  

The excel commands would be: "=CHISQ.INV(0.025,19)" "=CHISQ.INV(0.975,19)".

So for this case the critical values are:

[tex]\chi_{\alpha/2}[/tex] = 32.852

[tex]\chi_{1-\alpha/2}[/tex] = 8.907

Now putting the value in the formula:

[tex]\frac{19\times6.62}{32.852}\leq\sigma^2\leq\frac{19\times6.62}{8.907}[/tex]

3.829≤σ^2≤14.121

So the 95% confidence interval for the variance in the pounds of impurities would be (3.829, 14.121).

The length of the Hypotenuse for the given right angle triangle, is 10√5.

What is Hypotenuse?

A right-angled triangle's longest side, or the side opposite the right angle, is known as the hypotenuse in geometry. The Pythagorean theorem states that the hypotenuse's square length equals the sum of the squares of the lengths of the other two sides, and this can be used to determine the hypotenuse's length.

Let the two sides of right angle triangle are, a = 20 and b = 10.

We have to find the length of Hypotenuse.

Let x be the length of Hypotenuse.

So, by using the Pythagoras theorem,

[tex]a^2 + b^2 = x^2[/tex]

Plug a = 20, b = 10

[tex](20)^2 + (10)^2 = x^2\\400 + 100 = x^2\\500 = x^2\\x^2 = 500\\x = 10\sqrt{5}[/tex]

Take the LCM

So, we have the following equation

(2(x + 2) + 5x)/x(x + 2) = 1

So, we have

(2(x + 2) + 5x) = x(x + 2)

Open the brackets

2x + 4 + 5x = x² + 2x

Evaluate the like terms

x² - 5x - 4 = 0

Using a quadratic formula, we have

What is the Percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term per cent signifies. The letter "%" stands for it.

Example percentages include:

There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we imply that it is 50% of everything.

As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any topic are calculated in terms of percentages in academics.

if there is a 15 percent increase in the initial value then the value will be y = 1.15x

y is the price after the  increase

x is the price before the increase

Answer:

Angle = 71.08°

Step-by-step explanation:

Since we're given all of the sides, we're able to use any one of the trigonometric proportions.  I can go through all three to show how they all yield the same answer.

The sine proportion is [tex]\frac{opposite}{hypotenuse}[/tex]

Using the ? angle as our reference angle (which we can refer to as "a" for the sake of the math), the side measuring 70 units is the opposite side and the side measuring 74 units is the hypotenuse:

[tex]sin (a)=\frac{70}{74}\\ sin^{-1}=\frac{70}{74}=a = 71.07535558=71.08[/tex]

The cosine proportion is [tex]\frac{adjacent}{hypotenuse}[/tex]

Using a as our reference angle still, the side measuring 24 units is the adjacent side and the side measuring 74 units is the hypotenuse:

[tex]cos (a)=\frac{24}{74}\\ cos^-^1=\frac{24}{74}=71.07535558=71.08[/tex]

The tangent proportion is [tex]\frac{opposite}{adjacent}[/tex]

Using a as our reference angle still, the side measuring 70 units is the opposite side and the side measuring 24 units is the adjacent side:

[tex]tan(a)=\frac{70}{24}\\ tan^-^1=\frac{70}{24}=a=71.07535558=71.08[/tex]

Here we need to find the probability that x is less than or equal to 28.

According to a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.

Here first, we have to solve for the z-score using the formula below.

=> z-score = (x – μ) / σ

Here x refers the individual data value = 38

μ refers mean = 5

σ refers standard deviation = 15

Then when we apply the values on it, then we get,

1) y = -x -1

2) y + 4 = 3( x -2)

3) y = x + 1

Step-by-step explanation:

1)

The slope is the change in y over the change in x.  The y values from the points given is 0 and -1.  The x values from the points given is -1 and o

Slope: [tex]\frac{o - -1}{-1 - o}[/tex] = [tex]\frac{1}{-1}[/tex] = -1

y -intercept

y = mx + b  Use the point (0,-1) and the slope to solve for b

y = -1

m = -1

x = 0

y = mx + b

-1 = -1(0) + b

-1 = 0 + b

-1 = b  This is the y intercept.

y = mx + b

y = =x -1

2)

point-gradient form is

y -y = m (x-x)

y - -4 = 3 (x -2)

y + 4 = 3( x - 2)

3)

Parallel lines have the same slope.

slope is 1.  Use this and the point (0,1) to solve for b

y = mx + b

1 = 1(0) + b

1 = 0 + b

1 = b

y = x + 1

we have to solve it

Step 1 : Multiply both sides by 10

1.4 f ×10 + 1.1 ×10 = 8.3×10 - f ×10

=> 14/10(10f) + 11/10(10) = 83/10(10) - 10f

Step 2 : Subtract 11 from both sides

=> 14f + 11 - 11 = 83 - 10f -11

=> 14f = 72 - 10f

Step 3 : Add 10f both sides

=> 14f + 10f = 72 - 10f + 10f

=> 24f = 72

ans will be (c) 11 cm, 7 cm, 2 cm

Step-by-step explanation:

Though the sum of any two sides of a triangle should be always greater than the third side i.e.,

11 + 7 > 2

7 + 2 = 9 < 11

so, no triangle can be formed of such sides.
