(cos Ф -cos Ф)² + (cos Ф + cos Ф)²
Firstly: (cos Ф -cos Ф)² = 0² = 0
Secondly :(cos Ф + cos Ф)² = (2cos Ф)². = 4. (cos Ф)² = 4cos² Ф
Mind you when you raise a cosine (or sin or tan...) to the n power, the n power should affect the cosine only and NOT the angle Ф
Split the room into 2 rectangles
area = 5*4 + 3*3 = 29 sq ft
So the cost is 29*8 = $232
Answer:
You add all of the sides... or you can multiply one side with 4.

Answer:
40/76 or 10/19 or 52.63% (they are all equivalent)
Step-by-step explanation:
there are 76 parking spaces in total
30 parking spaces have numbers that are less than 31 (1 - 30)
that means that there are 76 - 30 = 46 spaces that are numbered 31 or higher
so the probability that Jillian parks on a parking space with a number ≥ 31 is 40/76 or 10/19 or 52.63%
Answer:
The answer is: m = 3/2
Step-by-step explanation:
The slope m = (y - y1)/(x - x1]
Replace the variables with the points given:
m = (2 - 5)/(1 - 3)
m = -3/-2
m = 3/2
