Answer:
6000 mL
Step-by-step explanation:
The prefix "milli-" is an SI standard prefix meaning 1/1000. So, 1 mL = (1/1000)L.
When doing dimension changes, you always want to use scale factors that have a value of 1, which is to say the numerator is equal to the denominator. For converting liters to milliliters, the scale factor you want will have mL in the numerator and L in the denominator:
(1 mL)/(1/1000 L) or (1000 mL)/(1 L)
To do your conversion, multiply your liter volume by this factor.
6 liters is 6000 milliliters.
__
You will notice that the dimensions "L" cancel, which is the point of the exercise.
_____
<em>Additional comment</em>
6 L is closer to 202.884 fluid ounces. The conversion factor is ...
Answer:
Step-by-step explanation:
If I'm interpreting that correctly, you are trying to solve this equation:
for theta. To do this, you will need a trig identity sheet (I'm assuming you got one from class) and a unit circle (ditto on the class thing).
We need to solve for theta. If I look to my trig identities, I will see a double angle one there that says:
We will make that replacement, then we will have everything in terms of sin.
Now get everything on one side of the equals sign to solve for theta:
We can factor out the common sin(theta):
By the Zero Product Property, either
or
Now look at your unit circle and find that the values of theta where the sin is 0 are located at:
The next one we have to solve for theta:
simplifies to
and
Look at the unit circle again to find the values of theta where the sin is -1/2:
Those ar your values of theta!
