t must equal √2h/g but I don't see that in the choices above
Answer:
Step-by-step explanation:
V-0.12V (first option) if we factor it it becomes
V(1-0.12)=0.88V (last option)
Answer:
66 squares are in the circle.
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.
