Answer:
there is no correct answer to this but I will give you 100 points so just keep reloading your page it will say FREEEEEEE POINTSSSSSSSS under math
Step-by-step explanation:
V = 20√(273 + t )
when v = 329
∴ 329 = 20 √(273 + t )
∴ √(273 + t ) = 329/20 = 16.45
273 + t = 16.45² = 270.6025
∴ t = -2.3975 ≈ -2 (<span> Rounded to the nearest degree )

Answer:
This is a function
Step-by-step explanation:
For every x value, there is at most one y value, so it can be expressed as a function.
Answer:
about 5.8cm
Step-by-step explanation:
Pythagorean theorem is
![a^{2} + b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
and using that sin is opposite/hypotenuse, you can find the third side of the triangle.
![11^{2}+(adjacent)^{2} = 61^{2} \\ 121+ (adjacent)^{2} = 3721 \\ (adjacent)^{2}=3600 \\ adjacent = 60](https://tex.z-dn.net/?f=11%5E%7B2%7D%2B%28adjacent%29%5E%7B2%7D%20%3D%2061%5E%7B2%7D%20%5C%5C%20121%2B%20%28adjacent%29%5E%7B2%7D%20%3D%203721%20%5C%5C%20%28adjacent%29%5E%7B2%7D%3D3600%20%5C%5C%20adjacent%20%3D%2060)
now you know adjacent is 60, so cos=60/61
