The cost per kilometer for Emanuel's taxi ride is given as follows:

$9/4.

To obtain the cost per kilometer of the tax ride, we apply the proportion, dividing the total cost by the distance of the taxi ride.

From the text given in this problem, the parameters are given as follows:

Then the cost per kilometer for Emanuel's taxi ride is found applying the proportion as follows:

Cost per kilometer = 32/14.22 = 2.25.

We have that the fraction equivalent of .25 is given as follows:

1/4.

Thus the proper fraction that represents the cost is given as follows:

2 + 1/4 = 8/4 + 1/4 = $9/4.

To be a relation of a function for every value of x there must be a single value of y thus the given relation is not a function.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given table,

At x = 9

y = 9 and y = 3

Since at a single value of x there exist two values of y thus it will not be a function.

Hence "The provided relation is not a function since there must only be one value of y for a relationship to be considered a function.".

In lambda expressions and lambda (λ) phrases, the Greek letter lambda () is used to signify binding a variable in a function. You can have typed or untyped lambda calculus.

Functions can only be used in typed lambda calculus if they are able to accept the "type" of data that the input is. The Greek symbol lambda () is commonly used to represent wavelength, which is equal to the speed (v) of a wave train in a medium divided by its frequency (f): wavelength = v/f. The majority of the time, students struggle to understand calculus because they don't practice after class, can't concentrate in class, have gaps in their math knowledge, and believe it's a waste of time.

The actions you can do to make calculus simple are listed below. Calculus is the most difficult math topic, and very few students, whether in high school or elsewhere, succeed in it. In vector space, linear algebra is a subset of abstract algebra. Matrix technology makes things less abstract and easier to understand because it is more concrete. The mean number of events within a particular period of time or space is denoted by the Greek letter lambda () in the Poisson distribution formula. For instance, = 0.748 floods annually.

First, by solving for y, convert the equation of the given line into slope-intercept form y=mx+c .You obtain the slope of the equation as m. Since the slopes of perpendicular lines are negative reciprocal, the slope of the line we're looking is the negative reciprocal of the perpendicular equation.

By entering the supplied point into the formula y = mx + b and solving for b, we arrive at the value of b. Consequently, the line's equation is formed.

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively.

m = y/x = y/x = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line may be shown as

tan θ = Δy/Δx

30×25=750messages

Answer:

The equation is m = 25d

Ashley would send 750 text messages after 30 days.

Step-by-step explanation:

The equation is y = mx + b

We see that each day the number of text increase by 25, so our equation is

m = 25d

Now we ask how many text messages Ashley would send in 30 days. We need to put 30 in for d and solve it.

m = 25(30)

m = 750 text messages

So, Ashley would send 750 text messages in 30 days.

According to the properties of geometry the correct option is C.

What is geometry?

The study of measurements, sizes, shapes, locations, angles, and proportions of objects is known as geometry.

Dilation represents the enlargement and compression of a figure. Whether it is an enlargement or compression, It totally depends on the scale factor.

If the absolute value of scale factor is more than 1, then it represents the enlargement and if the absolute value of scale factor is lies between 0 to 1, then it represents the compression.

Image and preimage are similar figures. It means the corresponding angles are congruent or corresponding sides are proportional.

It is given that LMN is dilated by a scale factor of 0.5.

Since scale factor is lies between 0 to 1, therefore it shows the compression.

Therefore sides of L'M'N' is smaller than LMN.

Since corresponding angles of similar figure are congruent.

So, options A, B and D represent the correct statements. Only option C represents a false statement because the sides of similar figure are proportional not congruent.

A transformation that leaves a geometric figure's size or shape unaltered is known as a rigid transformation (also known as isometry). is a unique type of metamorphosis in which a figure's size or shape are left unaltered.

During a rigorous alteration of the geometric object, the distance between each pair of its points is maintained. In other words, an object's size and shape are maintained through a hard transformation. For example, the rigid transformation of a triangle preserves the triangle's angles and lengths. Consider a rigid form distortion that resembles a cardboard shape.

There are translations, reflections, and isometric rotations. As a result, none of these changes have an impact on the figure's size. If neither the size nor the shape of the figures are changed, the figures are constant.

The term correlation coefficient is used to show the level of the relationship between the variables. If the correlation coefficient is very close to 1 then it means that there is greater association between the variables. If it is far from one then it means that the variables are not associated at all.

This is because any number to the power of 0 is equal to 1. This is part of the fundamental rules of exponents in mathematics. For example, if we take 2 to the power of 0, that would be equal to 2^0=1.

Similarly, 5^0=1, and so on. This is because any number to the power of 0 is equal to 1, regardless of the number. This is because any number multiplied by 1 is equal to itself. This holds true for 0 as well, and so 0^1=1. This is why the value of 0 1 is 1.

The solution to the system of equations is x = 3/2 and y = 7/4.

The given system of equations can be written as:

y = -x^2 + 4

y = 2x + 1

To solve this system of equations, we can use the substitution method. First, we'll substitute the expression for y in the second equation into the first equation. We can then solve the resulting equation for x.

In the first equation, [tex]y = -x^2 + 4[/tex] . Substituting this expression into the second equation, we get:

[tex]-x^2 + 4 = 2x + 1[/tex]

We can rearrange the terms on the left side of the equation to solve for x. To do this, we'll subtract 4 from both sides, then add x^2 to both sides:

-4 = 2x + 1 - 4

-4 + 4 = 2x + 1 - 4 + 4

0 = 2x - 3

Now, we'll divide both sides of the equation by 2 to solve for x:

0/2 = (2x - 3)/2

0 = x - 3/2

We can rearrange the terms on the right side of the equation to solve for x. To do this, we'll add 3/2 to both sides:

0 + 3/2 = x - 3/2 + 3/2

3/2 = x

Now that we have the value of x, we can substitute it into either equation to solve for y:

[tex]y = -x^2 + 4y = -(3/2)^2 + 4y = -(9/4) + 4[/tex]

y = 7/4

Therefore, the solution to the system of equations is x = 3/2 and y = 7/4.
