The domain of the function is not the set of all real numbers, that is why it is not from R to R

Here we want to see why the function f is not a function from R to R, where R is the set of the real numbers.

The function here is:

f(x) = 1/x

Notice that x is on the denominator, so we can't evaluate that function on x = 0.

So there is a real number that we can't use on that function, then the domain is not R, is R minus the element {0}

That is why f(x) is not a function from R to R, because the domain is not the set of the real numbers.

Answer:

Area = length x width (in feet)

Step-by-step explanation:

The area of a 2-dimensional shape can be found by multiplying its length by its width. The equation to find the area of a rectangle is:

Area = length x width

So if you know the length and width of a piece of glass in feet, you can use the above equation to find its area in square feet. For example, if the length of the glass is 10 feet and the width is 5 feet, the area would be:

Area = 10 feet x 5 feet = 50 square feet

So the equation to find the area of a piece of glass in square feet is:

Area = length x width (in feet)

It's worth noting that this equation applies to any 2-dimensional shape that has a length and a width, not just a rectangle.

The general solution to x squared dy over dx equals 3 plus 2y is given by 1/2 ln|3 + 2y| = -1/x + c, where c is an arbitrary constant.

To calculate this, we begin by taking the derivative of both sides of the equation with respect to x. We then rearrange the equation to yield 2y + x^2 dy/dx = 3. We divide both sides by x^2 so that dy/dx is isolated on one side of the equation, yielding dy/dx = (3 - 2y) / x^2. We can then integrate both sides of the equation, with respect to x, to yield 1/2 ln|3 + 2y| = -1/x + c, where c is an arbitrary constant. This equation is the general solution to x squared dy over dx equals 3 plus 2y.

Answer:4

Step-by-step explanation:

The graph demonstrates that the function g's line goes through the locations (0,2) and (2,8). The slope of the line is 3, implying that its equation is g(x) = 3x + 2.

The steepness or inclination of a line, route, or surface is measured by slope. It is the vertical distance divided by the horizontal distance between two locations on a line, route, or surface.

According to the graph, the function g is a line with a slope of 3 and a y-intercept of 2. This suggests that the line's equation is g(x) = 3x + 2. According to this equation, increasing the y-coordinate by one increases the x-coordinate by three. The line connects the points (0, 2) and (2, 8), which means that when x = 0, y = 2 and when x = 2, y = 8. This may be demonstrated by plugging the x-values into the equation, which will produce the matching y-values.

Note that if the family is to spend less than $60 dollars without further expenses, then they will have to spend nothing more than 6 hours. The inequality expression is given as: 36+4h < 60

First, the inequality expression is given as:

36+4h < 60

Where h is the number of hours they could spend.

We arrive at the above because we were given the following:

Cost of Movie = $36

Cost of parking Per Hour= $4

The maximum amount to be spent = $60

Thus, to find the number of hours the can spend without overshooting $60, we must find h. To do this, we must make h the subject of the formula by first removing 36 from both sides:

36+4h-36 < 60-36

4h < 24

h < 24/4

h < 6

What the above result show is that the number of hours that must be spent must be less than 6.

The cars receive the broadcast signal for length of about 36 miles.

The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.

A condition on a variable (or variables) is a pair of expressions in the variable (or variables) that have the same value. The solution or root of the equation is the quantity at which the variable's value satisfies the equation. If you swap the LHS and RHS, an equation still makes sense.

Equations can be categorized as either identities or conditional equations. For each value of the variables, an identity holds true. Only specific values of the variables make a conditional equation true. An equals symbol ("="), separating two expressions, is used to represent an equation.

Simultaneous equations are obtained:

[tex]$$x^2+y^2=1620 \\y=-\frac{1}{3} x+30\end{array}\right.$$[/tex]

[tex]$x^2+\left(-\frac{1}{3} x+30\right)^2=1620$[/tex]

simplifying the above equation, we get

[tex]$x^2-18 x-648=0$[/tex]

(x - 36)(x + 18) = 0

x = -18 and x = 36

The probability mass function of x  is P(0)= 1/8, P(1)= 3/8, P(2)= 3/8, P(3)= 1/8.

Here number of trials = 3

In tossing a coin for once, the outcomes of the trial are either head or tail.

The trials are independent.

probability of getting head(success)=p=1/2

probability of getting tail(failure)=1-p=1-(1/2)=1/2

Number of success=X

Since there are two mutually exclusive outcomes of independent trials, the probability mass function of Binomial = (nx)px(1−p)n−x(nx)px(1 − p)n−x {in this case n=3}

6 in 6,275 is 100 times greater than  6 in 62.75

What is place value?

Place value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value.

as,  6 in 6,275 have a place value 6000.

and in 62.75, 6 have place value 60.

So, the difference is

6000/60

=100

Hence, 6 in 6,275 is 100  times greater than  6 in 62.75

Step-by-step explanation:

The value of the 6 in 62.75 is 60, while it is 6000 in the number 6275. This is due to the concept of place value in the decimal number system.

In terms of place value, the value of the 6 in 62.75 is 60, because it is in the tens place. However, the value of the 6 in 6,275 is 6,000 because it is in the thousands place. This is based on the concept of place value in the decimal number system where each digit has a value depending on where it is located within the number. The further to the left a digit is, the larger its value.

The answer is O Congruent supplementary angles each have a measure of 90 or –12 + 11 < –1; true.

This can be proven by using the following formula:

p: 60 seconds = 1 minute

q: Congruent supplementary angles each have a measure of 90.

r: –12 + 11 < –1

For p, we can use the formula to calculate the number of minutes:

60 seconds * 1 minute = 60 minutes.

Therefore, 60 seconds = 1 minute.

For q, we can use the formula to calculate the measure of each angle:

2x = 90

Therefore, each angle has a measure of 45°.

For r, we can use the formula to calculate the result of the operation:

–12 + 11 = –1

Therefore, –12 + 11 < –1 is true.
