What is the symbol of ordered pair?

Answer:

The hourly charge is $4 per hour for the first 3 hours.

The rate then drops to $2 per hour until the end of the 6th hour.  

The hourly rate drops further to $1 per hour between the 6th and 10th  hours.

The maximum price of the bike rental is $30.

Step-by-step explanation:

The slope of the graph corresponds to the hourly rate for the bike rental.

During the first three hours of the bike rental, the price increases by $4 each hour.

Between the 3rd  and 6 th hours, the slope of the graph is 2, which means the hourly rate of the bike rental is $2 per hour.

Between the 6th and 10th hours, the rate is $1 per hour.

After the 10th  hour, the price, P, stops increasing. The maximum price of the bike rental is $30.

The second set of coordinates is known as the Polar Coordinates.

Polar coordinates are a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point (the pole) and an angle from a reference direction (the polar axis). The reference point is usually the origin (0,0) of a Cartesian coordinate system, and the reference direction is usually the positive x-axis of the Cartesian coordinate system. Polar coordinates are useful when dealing with circular shapes and symmetric patterns because all points on a circle can be represented by a single polar coordinate. For example, if you want to draw a circle, you only need to specify the center point, the radius, and the number of degrees you want to cover. Polar coordinates also allow for an easy conversion to Cartesian coordinates, which can be used for plotting points and finding distances. Additionally, polar coordinates can be used to determine angles and distances between two points in a two-dimensional plane. Polar coordinates are a powerful tool in mathematics and engineering, allowing for more efficient analysis of shapes and patterns.

The equation -3(4x - 8) = 6x + 12 has infinitely many solutions.

An equation has infinitely many solutions when the equation is true for all possible values of the variable. One way to identify that an equation has infinitely many solutions is to see if the equation is true when the variable is replaced by any value.

A system of equations is a set of two or more equations that involve the same variables. The goal is to find the values of the variables that satisfy all of the equations in the system. There are different methods to solve a system of equations, depending on the type of equations and the number of variables involved.

The equation that has infinitely many solutions is:

B. -3(4x - 8) = 6x + 12

To see this, we can simplify the equation to:

-12x + 24 = 6x + 12

-12x = 12

x = -1

Now, if we put x = -1 in the equation, we see that it is true. If we put x = -2, x=0, x = 1, x = 3 and so on, we can see that the equation is true for all values of x.

The slope of the line through the points is -5/7.

What is slope ?

A number that describes a line's direction and steepness is known as the slope or gradient of a line in mathematics.

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

The slope is calculated as the ratio of the rise, which is the vertical change between two points, to the run, which is the horizontal change between those same two sites.

Typically, a line's slope provides information about the steepness and direction of the line. Finding the difference between the coordinates of the locations will allow you to quickly compute the slope of a straight line connecting two points, (x1,y1) and (x2,y2).

Answer:

Opposite Sides are perpendicular (only correct answer)

Step-by-step explanation:

Not every parallelogram has diagonals that are perp to each other (form right angles.

The new velocity of the object is -4.04 m/s

Impulse is the change in momentum of an object which a force causes. It is  equal to the magnitude of the force multiplied by the length of time the force is applied.

Mathematically:

Impulse (I) = change in momentum = force(F) × time (t)

Also,

Ft = m(v-u)

I = m(v-u)

where m is the mass of the object, v is the new velocity and u is the initial velocity

From the given information; m = 148kg, u = -3.5m/s, I = -80 kg m/s:

I = m(v-u)

-80 = 148(v - (-3.5))

-80 = 148(v +3.5)

-80 = 148v + 518

148v = -80-518

The parabola g(x) is reasonable because it can be derived of parabola f(x) by rigid transformations.

Parabolas are represented by second order polynomials in vertex form, whose definition is shown below:

y - k = C · (h - k)²

Where:

In this problem we must create the expression for the image of the parabola by means of rigid transformations, that is, transformations that change the parabola without changing Euclidean distances. Most common rigid transformations are listed below:

The procedure is summarized below:

Now we proceed to apply the rigid transformations in that order:

Step 1

y = f(x) → y = f(x - 3)

y = x² → y = (x - 3)²

Step 2

y = f(x - 3) → y - 2 = f(x - 3)

y = (x - 3)² → y - 2 = (x - 3)²

Step 3

y - 2 = f(x - 3) → y - 2 = - f(x - 3)

y - 2 = (x - 3)² → y - 2 = - (x - 3)²

Step 4

y - 2 = - f(x - 3) → y - 2 = - f[0.5 · (x - 3)]

y - 2 = - [0.5 · (x - 3)]²

Step-by-step explanation:

We can write an equation of a line in slope intercept form when given a graph of a line by using the equation y = mx + c.

There are various forms in which an equation is present. Based on the given equation or graph values, we can determine the form we should use. The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

We first see the point where the line cuts the y-axis, then we calculate the slope of the line using the formula,

Slope= Δy/Δx

Once we get these values, we can substitute them in the equation for our final answer.

from the table, what do we observe?

As x is increasing by 5 units;

y is decreasing by 5 units

What this mean is that there is a negative correlation between both

This means the linear regression will go through every point, and will be a perfect fit. The correlation coefficient, r, of a data set is 1 if it is a perfect positive fit and -1 if it is a perfect negative fit; since the slope is decreasing, this is a negative correlation, and since it fits perfectly, it is -1.

Thus, what we have here is that, since the rate of increase/decrease on both ends is of equal magnitude but opposite signs, we can conclude that the correlation coefficient is -1

The z-score for a temperature of 71 degrees is -0.75.

What is the z-score?

When assessed in terms of standard deviation units, a raw score's location in relation to its distance from the mean is indicated by a z-score. If a value is above the mean, the z-score is positive; if it is below the mean, it is negative.

The raw score less the population mean, divided by the population standard deviation, is the z-score.

Here, the mean average temperature is 74°, standard deviation is 4, and the raw score is 71°.

The formula for calculating z-score is -

Z = (x-μ)/σ

Where x is raw score, μ is mean and σ is standard deviation.
