Answer:
½
Explanation:
According to the Unit Circle, tan240° [when it falls in between 180° and 270°] is √3, so we plug this into the sine function to get this:
sin240° - 210° → sin30° >> ½

** I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.
*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.
**** Now, 60° is the main possible answer, however, it falls in between 0° and 90°, not 180° and 270°.

Step-by-step explanation:
ANSWER= square root(-1) = i
STEP-BY STEP EXPLANATION:
Imaginary number. An imaginary number is the square root of a negative real number. (The square root of a number is a second number that, when multiplied by itself, equals the first number.)
(has to be a fraction)
I think it is 1/216
Answer:
Volume of acetic acid = 4L
Volume of water = 1L
Step-by-step explanation:
Total volume = 5L
The solution contains 80% acetic acid.
Volume of acetic acid in the solution = 80/100 x 5 = 4L
To get the volume of water present, we subtract the volume of acetic acid from the total Volume i.e
Volume of water = 5 — 4 = 1L
The 5 liter container contains 4 liters of acetic acid and 1 liter of water.
In order to determine the amount of acetic acid and water in the 5 liter container, we need to use the given concentration of 80% acetic acid. This means that 80% of the total volume is acetic acid and the remaining percentage is water.
To find the amount of acetic acid, we can multiply the total volume by the concentration: 5 liters x 0.8 = 4 liters of acetic acid.
To find the amount of water, we can subtract the amount of acetic acid from the total volume: 5 liters - 4 liters = 1 liter of water.
Hence, The 5 liter container contains 4 liters of acetic acid and 1 liter of water.
