The question is asking to convert the said decimal value in a simplest fraction form, base on my research and further calculation, I would say that the answer would be 3/10. I hope you are satisfied with my answer and feel free to ask for more
(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
F(x) = x^2 +5x + 3
= (x + 2.5)^2 - 6.25 + 3
= (x + 2.5)^2 - 3.25
That is vertex form. I am not sure what you mean by function form
Create and solve an appropriate equation: Maria's earnings = Liam's earnings
0.20x = $625+0.10x.
Find x.
0.10x = $625; thus, x = $6250. At this level of food sales, these two people earn the same amount.
