The slope of -10 as calculated from the data given is found out to be as 0.
Let's say y = -1= ,
Now, we know that the formula to calculate slope is y = mx+ b y .
This is known as slope-intercept form and can be written as ,
y = m x + b,
m = slope and b b= y-intercept.
y = mx +b y
y = m x + b
Therefore , by looking at this formula we can say that the value of m is 0 .
So , the slope is found out to be 0.
The slope is defined as the change in y coordinate with respect to the change in x coordinate of that line.

Rhonda' job i to drive a car for a company. Each month he i paid the ame alary. She i alo paid extra money for the number of mile he drive the car each month. • In July Rhonda drove 640 mile and wa paid a total of $3,502. 0. • In Augut Rhonda drove 820 mile and wa paid a total of $3,601. 0. Which function can be ued to find y, the total amount he i paid in a month if he drive × mile?
If Rhonda drives x miles in a month, she will be paid a total of $2,352 + ($0.55 * x).
We can use the information given to set up a system of equations to find the function that relates the number of miles driven (x) to the total amount paid (y).
Let's call the fixed salary that Rhonda receives each month "s" and the extra money she receives per mile driven "m".
Based on the information given, we know that in July, Rhonda drove 640 miles and was paid a total of $3,502. So, we can set up the following equation:
y = s + (m * 640) = $3,502
And in August, Rhonda drove 820 miles and was paid a total of $3,601. So, we can set up the following equation:
y = s + (m * 820) = $3,601
We can use these equations to solve for "s" and "m".
Subtracting the first equation from the second equation:
$3,601 - $3,502 = s + (m * 820) - s - (m * 640)
$99 = (m * 820) - (m * 640)
$99 = m * 180
m = $0.55
Now we can substitute this value of m back into one of the equations to solve for s
$3,502 = s + (0.55 * 640)
s = $2,352
So the function that relates the number of miles driven (x) to the total amount paid (y) is:
y = $2,352 + ($0.55 * x)
Thus, This means that if Rhonda drives x miles in a month, she will be paid a total of $2,352 + ($0.55 * x).

in 6-7 explain whether each graph represents a functions
A graph is a visual representation of data, showing relationships between different variables or values.
What is graph?Graphs are often used to represent a function, which is a set of inputs and outputs. A function is a relationship between two variables, where the output of the function depends on the input. In a graph, the input is represented on the x-axis, and the output is represented on the y-axis.
The first graph pictured is a linear function, which is a function that can be expressed as a straight line. This linear graph has a positive slope, meaning that as the input increases, so does the output. This graph represents a linear function because the output can be determined by the input, which is expressed as an equation in the form of y = mx + b.
The second graph pictured is a quadratic function, which is a function that can be expressed as a parabola.
This graph also has a positive slope, meaning that as the input increases, so does the output. This graph represents a quadratic function because the output can be determined by the input, which is expressed as an equation in the form of y = ax2 + bx + c.
Both of these graphs represent functions because they show a relationship between the input and output of a given data set. The input values are shown on the x-axis and the output values are shown on the y-axis, and these values can be used to determine the equation for the function.

Suppose a binomial trial has a probability of success of 0.2, and 500 trials are performed. What is the standard deviation of the possible outcomes? Round your answer to two decimal places.
10 is the standard deviation of the possible outcomes.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given a a binomial trial has a probability of success of 0.2, and 500 trials are performed
We need to find the standard deviation of the possible outcomes
To find the standard deviation of this binomial distribution, first find the variance by the formula:
= Number of trials x probability of success x ( 1 - probability of success )
= ( 500 x 0. 2 x ( 1 - 0. 2))
= 100
The standard deviation would be:

What is the standard form of equation y 3x 10?
The standard form of the equation y = 3x + 10 is -3x +y = 10.
To accomplish the given equation and bring it in the standard form for our problem, we first arrange it in standard form and then apply a little algebra to subtract 3x from both sides of the equation.
Given,
y = 3x + 10
Subtract 3x from each side.
Simplify: y - 3x = 3x + 10 - 3x.
y - 3x = 10
The x word should be placed first in the left-hand side arrangement.
-3x + y = 10
We discover that y = 3x + 10 is written as -3x + y = 10.
Ax + By = C is the equation of a line in its standard form, where A, B, and C are constants. There are several possible ways to express a line's equation, and if we are given a line that isn't in standard form, we can apply a little algebra to change the equation.

What do you call the triangle that have the same shape but not the same size?
The triangle that have the same shape but not the same size are similar triangles
What are Similar triangles ?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
If the respective sides of two triangles have the same ratio and the corresponding angles are equal, then the triangles are comparable (or proportion). Triangles that are similar will have the same form but may not be the exact same size.
Two triangles are said to be similar if their corresponding angles are equal. Equiangular triangles are what they are called. Two equiangular triangles were the subject of a significant finding made by the well-known Greek mathematician Thales. He applied the Basic Proportionality Theorem, sometimes known as the Thales Theorem, as a conclusion.

Step-by-step explanation:
since the triangle is isosceles then the altitude AD is the perpendicular bisector of BC , so
BD = [tex]\frac{1}{2}[/tex] BC = 7 cm
using Pythagoras' identity in right triangle ABD
AD² + BD² = AB²
AD² + 7² = 24²
AD² + 49 = 576 ( subtract 49 from both sides )

A′(3, 3)
A′(4.5, 2)
A′(4.5, 3)
Answer:
vertex of point A′ is A′(4.5, 3)
Step-by-step explanation:
To determine the vertex of point A′ after dilation, we need to know the coordinates of point A and the scale factor of the dilation.
In this problem, point A has the coordinates (3, 2) and the scale factor of the dilation is 1.5.
To find the coordinates of the dilated point, we multiply each of the original coordinates by the scale factor:
A'(x,y) = (1.5* x, 1.5*y)
So the coordinates of the point A' are:
A'(1.53, 1.52) = (4.5, 3)
Therefore, vertex of point A′ is A′(4.5, 3)
The vertex of point A after the dilation is A′(4.5, 3)
What is dilation?Dilation is a transformation that changes the size of a figure or an object without changing its shape.
The figure or object and its image after dilation are similar.
The size of the figure or object may increase or decrease based on a number called the scale factor.
Dilation is defined by a point called the center of dilation and the scale factor.
Given that, a triangle ABC, has been dilated by a scale factor of 1.5.
We need to determine the vertex of A',
The rule of dilation by a scale factor of k,
(x, y) → (kx, ky)
Therefore,
A'(x,y) = (1.5·x, 1.5·y)
So the coordinates of the point A' are:

Let us assume that x represents the rise and y represents the run,
According to the given problem,
x= 15 feet 34 inches
Converting feet into inches,
we know, 1 feet = 12 inches
so, 15 feet 34 inches = 15*12+34 = 214 inches
Now finding the rise in terms of x and y,
13 = y/x
substituting the value of x and solving for y:
13 = y/214
y = 13*214
y = 2782 inches
Converting inches into feet,
2782 inches = 2782/12 = 231 feet 10 inches
Thus, The rise is 231 feet 10 inches if the horizontal run of the roof is 15 feet 34 inches.
