640 x 0.30= 192
640-192= 448
448 is the answer
Answer:
The answer to your question is s = 399.5 m
Step-by-step explanation:
Formula

Data
V = 7 500 000 m³
h = 141 m
Substitution



s = 399.46 meters ≈ 399.5 meters
Well, notice the picture below
recall cosine is adjacent over hypotenuse
what's the hypotenuse? well, you can just use the pythagorean theorem to get "c" or hypotenuse

According to this <em>trigonometric function</em>, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:
![\displaystyle Phase\:[Horisontal]\:Shift → \frac{-\frac{π}{6}}{1} = -\frac{π}{6} \\ Period → \frac{π}{1} = π](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Phase%5C%3A%5BHorisontal%5D%5C%3AShift%20%E2%86%92%20%5Cfrac%7B-%5Cfrac%7B%CF%80%7D%7B6%7D%7D%7B1%7D%20%3D%20-%5Cfrac%7B%CF%80%7D%7B6%7D%20%5C%5C%20Period%20%E2%86%92%20%5Cfrac%7B%CF%80%7D%7B1%7D%20%3D%20%CF%80)
Therefore we have our answer.
