Answer:
Distance between A and B is 5400 meters
Step-by-step explanation:
Consider "D" the letter to identify distance between A and B
Let's use "t" to identify the time of the first encounter (Devi and Kumar), and create an equation that states that the distance covered by Devi (at 100 m/min) in time "t", is equal to the total distance D minus what Kumar has covered at his speed (80 m/min) in that same time:
Recall that distance equals the speed times the time:
distance= speed * time
First encounter:
100 * t = D - 80 * t
180 * t = D Equation (1)
Not, 6 minutes later (at time t+6) , Devi and Li Ting meet .
Then for this encounter the distance covered by Devi equals total distance d minus the distance covered by Li Ting:
100 *(t+6) = D - 75 * (t+6)
100 t + 600 = D - 75 t - 450
175 T + 150 = D Equation (2)
Now, let's equal equation (1) to equation (2), since D should be the same:
180 t = 175 t + 150
5 t = 150
t = 30
Then the time t (first encounter) is 30 minutes. Knowing this, we can use either equation to find D:
From Equation (1) for example: D = 180 * t = 180 * 30 = 5400 meters
The research was conducted on the ferris wheel. The number of cars or compartments is 32. The London Eye and the diameter of the wheel is 120m.
It is required to find the solution.
<h3>What is a statement?</h3>
A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.
Given:
The circumference of the wheel will be:
= 2πr
= 2π(120/2)
= 377m
The area of the wheel will be:
= πr²
= π(60²)
= 11310m²
The measure of a central angle in degrees will be:
= 360/32 = 11.25 degrees
The measure of a central angle in radians will be:
= 2π(11.25)/360
= 20 radians.
The arc length between two cars or compartments will be:
= 2π(60)(11.25)/360
= 11.78
The area of a sector between two cars or compartments will be:
= π(60²)(11.25)/360
= 353.43
An equation of a circle for your ferris wheel when the center of the ferris wheel is located at (0, 0) on a coordinate grid will be x² + y² = 3600.
Therefore, the research was conducted on the ferris wheel. The number of cars or compartments is 32. The London Eye and the diameter of the wheel is 120m.

Answer: C
Step-by-step explanation: graph C’s slope is 2x and has a y intercept of 0. This is the only right answer because A does not have a y intercept of 0, B’s slope is -2x, and D is not a function.
