Points (−7, 5) and (7, 5) on the coordinate grid below show the positions of two players of a football team: A coordinate plane is shown. There is a point at 7, 5 labeled Player 2. There is a point at negative 7, 5 labeled Player 1.
Answer:
you just need to make your math to right a little more math
Step-by-step explanation:
The distance between the two soccer players positioned at (-7, 5) and (7, 5) in a Cartesian coordinate system is 14 units, calculated using the difference in x-coordinates.
The question is focused on understanding the Cartesian coordinate system and calculating distances between points on this grid. To determine the distance between two points on a soccer field, one can apply the distance formula derived from the Pythagorean theorem. If the positions of the two players are (-7, 5) and (7, 5), the players are aligned horizontally and share the same y-coordinate. Therefore, their distance apart is simply the difference in their x-coordinates, which can be calculated by subtracting the x-coordinate of player 1 from that of player 2 or vice versa. The result is the absolute value of the difference, |7 - (-7)| = 14 units, which is their horizontal separation on the field.
x varies directly as y, and x = 153 when y = 9. Find x when y = 13.

The graph below shows the height an elevator travels, y, in x seconds:
A graph is shown with x axis title as Time in seconds. The title on the y-axis is Height of Elevator Above Ground in feet. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 125 in increments of 25 for each grid line. A line is shown connecting points on ordered pair 1, 25 and 2, 50 and 3, 75 and 4, 100. The title of the graph is Rate of Ascent.

X : 0 1 2 3 4 5 →→ Time in Seconds
Y : 0 25 50 75 100 125 →→Height of Elevator Above Ground in feet
Rate of change can be found by using two point slope form of line.
The slope of line joining two points [tex](x_{1},y_{1}) and (x_{2},y_{2})[/tex] is given by = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Taking two points (1,25) and (2,50) and finding the slope of line, that is Rate of change:

An empty rectangular tank, 40 cm long and 25 cm wide, contains 2 metal cubes of edge 10 cm. the tank is being filled with water flowing from a tap at a rate of 10 liters per minute. If it takes 3 minutes to fill up the tank, find the height of the tank.
The height of the tank is 0.5 cm.
Explanation:To find the height of the tank, we can use the formula:
Volume of water = base area × height
The base area of the tank can be found by multiplying the length and width: 40 cm × 25 cm = 1000 cm².
The volume of water flowing from the tap is given as 10 liters per minute, which is equivalent to 10000 cm³ per minute or 166.667 cm³ per second. Since it takes 3 minutes to fill up the tank, the total volume of water will be 3 minutes × 166.667 cm³ per second = 500 cm³.
Now, we can plug these values into the formula to find the height:
500 cm³ = 1000 cm² × height
Dividing both sides by 1000 cm² gives:
height = 0.5 cm
Therefore, the height of the tank is 0.5 cm.
Which of the following coordinates of point C would make triangle ABC similar to triangle LMP ? Look at pic attached :) thank you .
which of the following are exterior angles ?
Answer:
A, C, and E
Step-by-step explanation:
The exterior angles are ∠2, ∠3, ∠4 and ∠6.
The correct options are E, F, A, and C.
Based on the information provided, we can identify the exterior angles by their positions outside the triangle. From the given options, the exterior angles are: ∠2, ∠3, ∠4 and ∠6.
Exterior angles are formed by extending one side of the triangle outward, and they lie outside the triangle itself. In this case, angles ∠1 and ∠5 are interior angles because they are inside the triangle, while angles ∠2, ∠3, ∠4 and ∠6 are exterior angles as they extend beyond the sides of the triangle.

What is expansion?
Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.
In mathematics, every real-world issue may be transformed into an equation, sometimes in the form of a factor, which must then be expanded to get a solution.
If you solve a factor by opening the bracket then you will go to get on some expanded term called expansion.
Area of rectangle = length × width
Given,
Area of rectangle rug = (3x + 9)
So,
length × width = (3x + 9)
length × width = 3(x + 3)
So out of 3 and (x + 3), one would be the length and one would be the width.

A. 184 pi units^2
B. 304 pi units^2
C. 248 pi units^2
D. 496 pi units^2
The surface area of the right cone with a radius of 8 and slant height of 15 is,
SA = 184π units³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Radius of cone = 8
Slant height = 15
Since, The surface area of the right cone is,
SA = πr (r + l)
where,
r is the radius of the cone
l is the slant height of the cone.
Hence, We get;
SA = π × 8 (8 + 15)
SA = π × 184
SA = 184π units³
Thus, The surface area of the right cone with a radius of 8 and slant height of 15 is,
SA = 184π units³

Given the exponential function A(x) = P(1 + r)x, what value for r will make the function a growth function?
Answer:
The function is a growth function when [tex]r>0[/tex].
Step-by-step explanation:
We are given,
The exponential function is [tex]A(x)=P(1+r)^x[/tex], where P= initial value and r= rate of change.
Now, we know,
1. The function is an exponential growth if their is positive rate of change.
2. The function is an exponential decay if their is negative rate of change.
