The rational inequality f(x) > 0 has the solution x > - 7

A rational inequality is an inequality in the form of a fraction

Given the function f(x) = (x + 7)/(x² - 4x + 3)

To find the value of x for which the function f(x) > 0, we proceed as follows

Given that f(x) > 0

So, this means that

(x + 7)/(x² - 4x + 3) > 0

This implies that

x + 7 > 0

Subtracting 7 from both sides, we have that

x + 7 - 7 > 0 - 7

x + 0 > - 7

x > - 7

So, f(x) > 0 has the solution x > - 7

The value of the fraction expression -2 1/2 - (-4 3/5) is 2 1/10

From the question, we have the following parameters that can be used in our computation:

−2 /2/1 −(−4 3/5)

Express properly

So, we have the following representation

-2 1/2 - (-4 3/5)

Remove the brackets

This gives

-2 1/2 - (-4 3/5) = -2 1/2 + 4 3/5

Express the denominator as 10

So, we have

-2 1/2 - (-4 3/5) = -2 5/10 + 4 6/10

Evaluate the difference

-2 1/2 - (-4 3/5) = 2 1/10

Hence, the solution is 2 1/10

Given a right angle triangle with:

y = 8.00 m

r = 10.0 m

(a) We are to find the length of the unknown side x?

Using pythagoras theorem:

r² = x² + y²

x² = r² - y²

x = √r² - y²

Inputting values:

x = √10² - 8²

x = √100 - 64

x = √36

x = 6 m

Therefore, the length of the unknow side x is 10 m.

(b) The tangent of θ

Using SOHCAHTOA

Tan θ = Opposite/Adjacent

Opposite = y = 8 m

Adjacent = x = 6

Tan θ = 8/6

Tan θ = 1.3

(c) Sin σ

Sin σ = Opposite/Hypotenuse

Opposite = x = 6 m

Hypotenuse = r = 10

Sin σ = 6/10

Sin σ = 0.6

The cost of 20 T-Shirt will be 2560 when cost of one t-shirt is 128.

When a selling price and profit are provided, cost price equals selling price plus profit. When the selling price and loss are disclosed, cost price equals selling price plus loss.

Profit is calculated as S.P. - C.P. If the selling price is less than the cost price, the difference between the two is the loss incurred. Loss is also equal to C.P. - S.P.

We must divide the gross profit by the entire revenue for the year, multiply by 100, and then find the gross profit margin. We must divide net income (or net profit) by the entire annual revenue before multiplying the result by 100 to get the net profit margin.

The numbers are 1 and 8.

We have,

Let's assume the lesser number as "x" and the greater number as "8x".

According to the given information, when the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number:

8x - x = 5x + 2

Simplifying the expression:

7x = 5x + 2

Subtracting 5x from both sides:

2x = 2

Dividing both sides by 2:

x = 1

So, the lesser number is 1 and the greater number is 8 times that, which is 8.

Therefore,

Answer:

Step-by-step explanation:

a) The formula for the regression function is:

Maintenance Cost = 54.7757 + 120.689 x Age of Car

b) The slope of the regression equation is 120.689. This means that on average, for every one year increase in the age of a car, the maintenance cost is expected to increase by $120.689.

c) To construct a 95% interval to predict the maintenance cost for a car that is 7 years old, we can use the formula:

Y = a + bX ± tα/2 * SE

where Y is the predicted maintenance cost, a is the intercept, b is the slope, X is the age of the car, tα/2 is the t-value for the 95% confidence level with n-2 degrees of freedom (11 in this case), and SE is the standard error of the estimate.

Plugging in the values, we get:

Y = 54.7757 + 120.689 * 7 ± 2.201 * 11.8442

Y = 923.167 ± 26.010

Therefore, we can be 95% confident that the maintenance cost for a car that is 7 years old will be between $897.16 and $949.17.

d) The null hypothesis is that there is no significant linear relationship between the average maintenance cost and the age of a car in years. The alternative hypothesis is that there is a significant linear relationship between the average maintenance cost and the age of a car in years.

To test the hypothesis, we can perform a t-test on the slope coefficient using the t-statistic and the p-value provided in the output. The t-statistic is 10.1898, which is much greater than the critical t-value at the 0.05 level of significance for a two-tailed test with 11 degrees of freedom (2.201). The p-value is 0.0000, which is less than the significance level of 0.05. Therefore, we can reject the null hypothesis and conclude that there is a significant linear relationship between the maintenance cost and the age of the car in years.

The gametes FG and FG represent the two possible combinations of alleles for the FFGG genotype.Assuming that the genes are not linked and assort independently, an individual with the genotype FFGG would produce gametes with the following possible genotypes:

FG

FG

Each gamete receives one allele from each gene, and since the individual has homozygous dominant alleles for both genes (FF and GG), each gamete will receive one dominant allele from each gene. Therefore, all of the individual's gametes will have the genotype FG. This individual is said to be homozygous dominant for both genes.

An FFGG individual has two pairs of alleles, one for each gene. Since they are not linked and assort independently, the gametes produced by this individual will have only one allele for each gene, randomly selected from the two alleles in the individual's genotype.

In this case, the possible gametes produced by an FFGG individual would be FG and FG. Each of these gametes would have one allele for each of the two genes. The first allele could be either F or f, and the second allele could be either G or g. Therefore, the gametes FG and FG represent the two possible combinations of alleles for the FFGG genotype.

The 66th derivative of f(x) is the same as the second derivative of f(x). Thus, we can calculate the 66th derivative as follows f''(x) = -4sin(x).

The derivative of a function is the rate at which the function changes with respect to its input variable. It is a fundamental concept in calculus and is used in many areas of mathematics, science, and engineering.

The derivative of the function f(x) = 4sin(x) with respect to x is:

f'(x) = 4cos(x)

Taking the derivative again, we get:

f''(x) = -4sin(x)

Taking the derivative 3 times, we get:

f'''(x) = -4cos(x)

Taking the derivative 4 times, we get:

f''''(x) = 4sin(x)

We notice that the derivative of f(x) repeats every 4 times, alternating between sin(x) and cos(x) with a sign change. Therefore, to find the 66th derivative of f(x), we can simplify the calculation by considering the remainder when 66 is divided by 4:

66 mod 4 = 2

This means that the 66th derivative of f(x) is the same as the second derivative of f(x). Thus, we can calculate the 66th derivative as follows:

f''(x) = -4sin(x)

Therefore, the 66th derivative of f(x) is:

f^(66)(x) = f''(x) = -4sin(x)

The values of $k$ and $m$ for which the system of equations has infinitely many solutions are $k = -1$ and $m = 11$.

To find the values of $k$ and $m$ for which the given system of equations has infinitely many solutions, we can start by analyzing the equations and their coefficients.

The system of equations is:

$3a + 2b = 2$

$6a + 2b = k - 3a - mb$

To have infinitely many solutions, the two equations must represent the same line or be linearly dependent. This can occur when the coefficients of the variables in the two equations are proportional.

Comparing the coefficients of $a$ and $b$ in the two equations, we have:

For $a$: $3$ and $6$ are proportional (doubled)

For $b$: $2$ and $2$ are proportional (equal)

Since the coefficients of $b$ are already proportional, we focus on the coefficients of $a$ to determine the condition for infinitely many solutions.

The coefficient of $a$ in the first equation is $3$, while in the second equation, it is $-3$. For these coefficients to be proportional, we need:

$3 = -3 \cdot k$

$-3k = 3$

$k = -1$

Now that we have determined the value of $k$, we need to find the corresponding value of $m$ to satisfy the condition for infinitely many solutions.

Using $k = -1$ in the second equation, we have:

$6a + 2b = -1 - 3a - mb$

Rearranging the equation:

$9a + (m - 2)b = -1$

For the coefficients of $a$ and $b$ to be proportional, we need:

$9 = -1 \cdot (m - 2)$

$-m + 2 = -9$

$m = 11$

Therefore, the values of $k$ and $m$ for which the system of equations has infinitely many solutions are $k = -1$ and $m = 11$.
