Answer:
The answer is
miles.
Step-by-step explanation:
To solve this is pretty easy,
We know that the equation is
, and since we have to find the distance in 21 seconds, you just have to substitute the variable.
![t=time\\d(t)=186000(t)\\d(21)=186000(21)\\d(21)=3,906,000](https://tex.z-dn.net/?f=t%3Dtime%5C%5Cd%28t%29%3D186000%28t%29%5C%5Cd%2821%29%3D186000%2821%29%5C%5Cd%2821%29%3D3%2C906%2C000)

Answer:
1,75 kg
Explanation:
1 kg = 1000 g
2.5 kg = 2.5 × 1000 g = 2500 g
2500 g - 750 g = 1750 g
1750 g = 1750 ÷ 1000 kg = 1.75 kg

Answer:
Answer: The answer is option B.
Step-by-step explanation:
Here,
We have,
![{ \sin }^{2} theta \: + {cos}^{2}theta = 1](https://tex.z-dn.net/?f=%20%7B%20%5Csin%20%7D%5E%7B2%7D%20%20theta%20%5C%3A%20%2B%20%20%7Bcos%7D%5E%7B2%7Dtheta%20%20%3D%201)
![{cos}^{2} \: theta = 1 - {sin}^{2} \: theta](https://tex.z-dn.net/?f=%20%7Bcos%7D%5E%7B2%7D%20%5C%3A%20theta%20%20%3D%201%20-%20%20%7Bsin%7D%5E%7B2%7D%20%20%5C%3A%20theta)
![cos \: theta = \sqrt{1 - { \sin }^{2}theta }](https://tex.z-dn.net/?f=cos%20%5C%3A%20theta%20%3D%20%20%5Csqrt%7B1%20-%20%20%7B%20%5Csin%20%7D%5E%7B2%7Dtheta%20%7D%20)
So, it's true; and it lies in quadrant 1 and 4.
The reason according to the "CAST" rule cos theta is in 1st and 3rd quadrant cos theta is positive.
