The domain of f(x) = 3x - 2 is (-∞, +∞) or the set of all real numbers.

The domain of a function is the set of all input values (x-values) for which the function produces a valid output (y-value). For f(x) = 3x - 2, the domain is all real numbers.

In other words, for any value of x, whether it is a whole number, a fraction, a decimal or a negative number, we can substitute it into the function and find the corresponding output. Therefore, the domain of f(x) = 3x - 2 is (-∞, +∞) or the set of all real numbers.

Answer: c

Step-by-step explanation:

The domain of the function y = √(x - 5) is x >= 5, that is [5, ∞).

The domain of the function y = sqrt(x - 5) is the set of all input values (x-values) for which the function is defined.

In this case, the square root function is defined for all non-negative values of x - 5. If x-5 is negative, it would result in an imaginary number, which is not defined. However, since x - 5 cannot be negative, x must be greater than or equal to 5. Therefore, the domain of the function y = √(x - 5) is x >= 5.

The line equation for Carmen's donation plan is y + 2x ≤ 460.

Please refer to the attached graph below for the corresponding region.

From the case, we know that:

City youth fund = x

Educational growth foundation = y

Educational growth foundation = 2 city youth fund

Total budget = $460

Based on the case, we know that:

y = 2x --> the slope of the line constraint should be 2

Then, the line equation for this condition should be:

y + 2x ≤ $460

To construct the graph, we need to find the point constraint first.

(y= 0)

(0) + 2x = 460

x = 230 --> (230, 0)

(x = 0)

y + 2(0) = 460

A 95% confidence interval for the mean of 3243 dollars.

In statistics, the confidence interval formula is used to express the degree of uncertainty surrounding a sample estimate of a population parameter. It is used to describe the degree of uncertainty surrounding a sampling technique.

Given random sample = 55

mean = $2900

standard deviation = $1300

Confidence Interval = m ± z(SD/√n)

n = Number of terms

m = Sample average

SD = Standard Deviation

z = Value corresponding to confidence interval in z table

value of z for 95% confidence interval is 1.96,

substitute the values in formula,

Confidence Interval = m ± z(SD/√n)

Confidence Interval = 2900 ± 1.96(1300/√55)

Confidence Interval = 2900 ± 343.581

Confidence Interval =  3243.581

Confidence Interval =  3243

The number of hours it would take Miller's family to reach their destination is [tex]2\frac{2}{3}[/tex] hours. This can be solved using the concept of fractions.

A fraction is expressed as p/q, where q ≠ 0. Proper fractions, in which the numerator is less than the denominator, and improper fractions, in which the numerator is higher than the denominator, are the two sorts of fractions.

Given, The Miller family must drive 8 hours to reach their destination.

The first time they stopped after driving  hours and again for the second time they stopped after driving  hours.

Therefore the total hours they drive is,

= [tex](2\frac{2}{3}+2\frac{2}{3})[/tex] hours.

= (8/3 + 8/3) hours.

= 16/3 hours.

= [tex]5\frac{1}{3}[/tex] hours.

So, The number of hours they still need to drive is,

The probability of 50% shows that the  mean cholesterol level of the sample will be no more than 210 for the given mean and standard deviation.

As given in the question,

Area average represents the mean ' μ ' = 210 mg /dL

Standard deviation 'σ ' = 30 mg /dL

Sample 'n' =  48

Normal distribution 's' = σ /√n

A hole occurs when there is a duplicate factor on the numerator or denominator. This is not the case here, so there are no gaps.

The denominator of f(x) cannot be zero because f(x) would become undefined. The values that x cannot be are obtained by equating the denominator to zero and solving.

To solve 5x² + 2x + 1 = 0

This does not factor, so verify the discriminant.

Here, a = 5, b = 2, and c = 1.

b² - 4ac = 4 - 20

= -16

Because the discriminant is 0, there are no real roots, and thus no vertical asymptotes.

Horizontal asymptotes can be found as

[tex]\lim_{x \to \infty}[/tex] , f(x) -> c

Divide the terms on the numerator/denominator by the highest power of x, x².

f(x) = (3x² /x² )/((5x²/x² )+(2x/x²) +(1/x²))

     = 3/ 5 + 2/x + 1/x²

Since x -> ±∞. f(x) -> 3/5 + 0 + 0

= y = 3/5

When there is a duplicate factor on the numerator/denominator, a hole occurs. This is not the case in this case, so there are no holes.

To find out the number of roses David would have to buy for both florists to charge him the same amount, we set the two equations equal to each other and solve for x:

2x + 10 = 1x + 19

On average, an underground storage tank has a remaining useful life of between 10-20 years depending on the construction, maintenance, and environment it is in. The tank's remaining useful life is also dependent on the type of material used in its construction.

Tanks constructed from steel or fiberglass have a life span of around 15-20 years, while concrete tanks have a longer life expectancy of up to 25 years.  In this case, the tank has been in place for 15 years, which puts it at the midpoint of its expected life expectancy.

Depending on the maintenance and environment that the tank has been subjected to, it is not unlikely that it could last longer than its expected life, but it is recommended to inspect the tank periodically to ensure that it is still in good condition. If the tank is not properly maintained, the remaining useful life may be significantly shorter.

The solution set to the given system of equation is -

x = 4 & y = 1.5.

Given is the system of linear equations as -.

- 5x + 6y = - 11

6y = x + 5

In mathematics, a system of linear equations is a collection of one or more linear equations involving the same variables.

The types of systems of linear equations are as follows:

The system of linear equations is -

- 5x + 6y = - 11

6y = x + 5

We can write -

6y = x + 5

x = 6y - 5

Now, we can write -

- 5(6y - 5) + 6y = - 11

- 30y + 25 + 6y = - 11

- 24y = - 11 - 25

- 24y = - 36

y = 36/24

y = 9/6

y = 3/2

y = 1.5

Then, we can write -

x = 6 x 3/2 - 5

x = 9 - 5

x = 4

Therefore, the solution set to the given system of equation is -

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given:

The altitude of an equilateral triangle is 4.2 meters long.

let x is the measure of the side of the equilateral.

Using Pythagoras theorem

x = √(4.2)(4.2) + (x/2)(x/2) )

x = √( 4.2)² + (x²/4) )

x² = 17.64 + x²/4

3x²/4 = 17.64

The natural logarithm function gradually increases as x rises to positive infinity and gradually decreases as x approaches zero. Only for x>0 is the natural logarithm function ln(x) defined. Therefore, it is unknown what a negative number's natural logarithm is.

A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459. 

After that, the definition of the natural logarithm can be expanded to include logarithm values for all non-zero complex numbers as well as negative numbers, albeit this results in a multi-valued function.

When seen as a real-valued function of a positive real variable, the natural logarithm function is the exponential function's inverse. Not just e, but any positive base other than 1, logarithms can be defined.

However, compared to the natural logarithm, logarithms in other bases only differ by a fixed multiplier.
