The "vanilla" y=cos(x) function oscillates between -1 and +1. In the given function, only a multiplication with 3 is applied. The min and max scale accordingly, so the maximum becomes +3 and the minimum -3.
The x interval of <span>[-2π, 2π] ensures that all y values are enclosed; the cosine makes two full sweeps.</span>
Answer:
The angles opposite each other when two lines cross. They are always equal. In this example a° and b° are vertical angles.
Answer:
3/10, 2/5, 7/10, 3/4
Step-by-step explanation:
3/10 is 30%. 2/5 is 40%. 7/10 is 70%. 3/4 is 75%. Or you could multiply the denominators so that all denominators have the value of 20. Then it can be arranged. For 3/4, you can multiply everything by 5 to get 15/20. for 3/10, you can multiply everything by 2 to get 6/20. For 2/5, you can multiply everything by 4 to get 8/20. And for 7/10, you can multiply everything by 2 to get 14/20. Now you can arrange everything, starting with 3/10, then 2/5, then 7/10, and finally 3/4.
