180/3 = 60
Therefore the car traveled 60km per hour.
Answer:
Quadrant 4
Step-by-step explanation:
The x value is positive so it is either in 1 or 4
The y value is negative so it is either 3 or 4
To meet both conditions, it must be 4
Given:

To find:
The correct equivalent equation.
Solution:
We have,

Taking sin on both sides, we get

![[\because \sin (\sin^{-1}\theta )=\theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%20%28%5Csin%5E%7B-1%7D%5Ctheta%20%29%3D%5Ctheta%5D)
Interchanging the sides, we get

Therefore, the correct option is 4.
