A Binomial is a Polynomial with two terms:
Answer:

Step-by-step explanation:
We want to solve the equation:

Over the interval [0, 2π).
First, notice that this is in quadratic form. So, to make things simpler, we can let <em>u</em> = cos(x). Substitute:

Rearrange:

Factor:

Zero Product Property:

Solve for each case:

Back-substitute:

Using the unit circle:

Four options are given for this question, which are: 15/8, 49/64, 56/8 and 21/24.
7/8 = 0.875
15/8 = 1.875
49/64 = 0.7656
56/8 = 7
21/24 = 0.875.
The fraction that has a value that corresponds with that of 7/8 is 21/24, therefore, 21/24 is the correct option.
Answer:
353.6
Step-by-step explanation:
White blood cells in average drop of blood = 1.6 * 104 = 166.4
White blood cels in rare drop of blood = 5 * 104 = 520
Difference between the number of white blood cells in a rare drop of blood and the number of white blood cells in an average drop of blood
= 520 - 166.4 = 353.6
