Answer:
The denominator of the fraction is 2x and the answer is a= -
Step-by-step explanation:
Suppose we have a quadratic equation of the form:
ax²+bx+c
The axis of symmetry of the parabola is given by:
From here, we must clear the value of a.
For this, we follow the following steps:
1) Pass 2a multiplying to the other side of the equation:
2ax=-b
2) Clear the value of a by passing 2x to divide:
I will take a go at this. Imagine you had 10 chairs to put people in, and you had 10 people. For the first chair, you can pick out of 10 people, for the second chair, you have 9 people to pick from, and so on until the last chair, where you don't have a choice. So, to find the possible ways you can sit people in the chairs, you do 10*9*8*7*6*5*4*3*2*1, or you can denote it as 10!, where ! means factorial. So you get 3628800, and at first you might think that would be the answer, but we are talking about a circular arrangement here. So, two arrangements would be counted as different just because it turns by one person (Shown in picture). So since we dont count the first one, it should just be 9! instead of 10! And 9! equals 362880 (One less zero than the other answer). That should be the right answer

Answer:
Yes, he will have enough time to watch the entire film.
Step-by-step explanation:
5:30 to 6:30 is 1 hour of the movie completed.
6:30 to 7:30 is 2 hours completed.
7:30 plus 30 minutes brings him to 8:00.
8:00 plus the additional 5 minutes brings Greg to 8:05.
His movie ends at 8:05, so he will be able to watch the entire movie before going out.
