Answer:
≈ 4,22 m
Step-by-step explanation:
volume = 20000L = 20000 dm^3 = 20 m^3
diameter = 2,4m
the volume of a cilinder is π * r^2 * h (height)
20 = π * 1,2^2 * h
h = ≈ 4,42 m
When you add 8 to the end of a function formula, the graph moves UP 8 units. This is often called either a translation or vertical shift.
We have 112.5 = 225/2; cos112.5 < 0 because 90 < 112.5 < 180;
cos 112.5 = cos(225/2);
We use the trigonometric formula: cos(x/2) = -
;
Then, cos(225/2) = -
;
We have the formula: cos(270 - x) = -sinx (because cos(a-b) = cosacosb + sinasinb);
Then, cos225 = cos(270-45) = -sin45 = -
Finally, cos112.5 = -
cos 112.5 = cos(225/2);
We use the trigonometric formula: cos(x/2) = -
Then, cos(225/2) = -
We have the formula: cos(270 - x) = -sinx (because cos(a-b) = cosacosb + sinasinb);
Then, cos225 = cos(270-45) = -sin45 = -
Finally, cos112.5 = -
