This is the formula of finding the hypotenuse: a² + b² = c².
So the legs would be a and b.
4² + 4² = c²
c² = 16 + 16
c² = 32
c = √32 (Option C)
This question is asking "Where does cosine equal

?"
Based on our unit circle values and the domain of the cos^{-1} function, we see that at 30 degrees, or

, cosine is equal to

.

Answer:
The pharmacy should give Marilyn 135 tablets to fill the isoniazid for 45 days

Marilyn has to take isoniazid 100 milligrams tablet 3 times a day which means three tablets a day.
The pharmacy has to provide the tablets for 45 days
So,
Total tablets that will be provided by the pharmacy are:
45*3 = 135 tablets ..
So the formula for finding the area of a cylinder is

. r=radius. If we put the numbers into the equation it is

We get 6 as the radius because half of 12 is 6. 6 squared is 36 and 6*14= 84. So our equation is now

. 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(36)+6.283(84). Just multiply them. 226.188+527.772= 753.96 is your final answer.
