The graph is periodical meaning that it repeats itself after some point. This is because the motion of the wheel makes the car move up and then come back down again. Each local min point is likely where the riders get on the ride, since its closest to the ground. Each local max point is the highest point on the graph indicating when the car is at the top of the wheel.

Let's say that the vertical distance from the lowest point to the highest point is 50 feet, just as an example. This would mean the amplitude is half that at 50/2 = 25 feet. The amplitude represents the vertical distance from the center line to either the highest or lowest point.

The period describes how long each cycle takes. For instance, if it takes 60 seconds for a specific car to go from the bottom position, loop around, and then come back to the bottom position, then the period is 60 seconds. The frequency is simply 1 over the period. Though the frequency may not be used as much.

So overall this curve is likely a sine or cosine curve (depending on the phase shift of course). Also there's a vertical shift as well. Because we don't have any numbers to work with, the actual sine or cosine function cannot be determined.

Answer:

  DE ≈ 14.91

Step-by-step explanation:

Make use of the relationships between sides and angles in a right triangle. These are summarized by the mnemonic SOH CAH TOA:

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

__

The side DE is opposite the angle 19°, so the sine or tangent relation will be involved. The sine relation requires you know hypotenuse EF. The tangent relation requires you know adjacent side DF.

The only common side between triangles CDF and DEF is side DF. That side is opposite the given 61° angle. The given side length (CF = 24) is adjacent to the 61° angle.

This means you have enough information to use these relations:

  tan(61°) = DF/CF = DF/24

  DF = 24·tan(61°)

and

  tan(19°) = DE/DF

  DE = DF·tan(19°) = (24·tan(61°))·tan(19°) . . . . . use DF from above

  DE ≈ 24(1.804048)(0.344328) ≈ 14.908

The length of DE is about 14.91.

Put the following Points on a plane.
jeka57 [31]

Answer:

A (3, 1/2) B (-3/2, -7/4) C (7/5, 9/2)

Just a helpful tip for next time you need to graph something, you can look up "Graph Generator" and click on one of the first couple links and then you can put in your points. It makes it easier on the brain to be able to see and understand an accurate, and clean graph with the points on it.

dezoksy [38]

Answer:

  the square rug will cover 0.33 square feet more

Step-by-step explanation:

The area of a rectangle is the product of its length and width. The area of the rectangular rug is ...

  (4.8 ft)(8.2 ft) = 39.36 ft^2

Similarly, the area of the square rug is ...

  (6.3 ft)(6.3 ft) = 39.69 ft^2

The square rug has the larger area by ...

  39.69 -39.36 = 0.33 . . . square feet
