Answer: 30° and 330°
<u>Step-by-step explanation:</u>
sec θ =

cos θ = 
cos θ = 
cos θ = 
cos θ = 
Look at the Unit Circle to see that cos = at 30° and 330° ( which is equivalent to π/6 and 11π/6)
Answer:
Working memory
Step-by-step explanation:
Working memory is a system the brain uses for temporarily storing and managing the information required to carry out complex cognitive tasks. The central executive part of the prefrontal cortex at the front of the brain is responsible for working memory. It serves as a temporary store for short-term memory, where information is kept available while it is needed for current reasoning processes.
So to be successful in holding the number 2.82 in my head while sorting, one must keep the information maintained in short-term storage by using one's working memory.

Let x be the size of the small room and 2x, the big room
The larger room requires 3 coats and the smaller, 2 coats
All requires exactly 8 gal.
2.x + (2x).3 = 8 Gal, 8x = 8 and x = 1 (size of te smallest)
if it's the small room, then it will need 2 coats or 2x1 = 2 Gal, and the paint left is 8-2 = 6 Gal.
if it's the large one, 6x or 6 Gal, and remaining 2 Gal
Answer:
If we used the quadratic formula to solve the equation we can say:
-b = -5
b² - 4ac = 13
2a = 2
Solving the first and last equations we get b = 5 and a = 1. Substituting these values into the second equation we get:
25 - 4c = 13
Solving this we get c = 3 so the answer is x² + 5x + 3.
