Answer:

Vertex: (0, 0)

Focus: (0, \frac{1}{16})

axis of symmetry: x = 0

Directrix: y = -\frac{1}{16}

solution(s): x = 0

Step-by-step explanation:

Vertex:

The equation for a parabola is y = a(x - h)² + k

the vertex is the point (h, k), so in this equation the vertex is (0, 0)

Focus:

The equation for the focus of a vertical parabola is 4p(y - k) = (x - h)²

(p is the distance from the vertex to the parabola)

axis of symmetry:

The axis of symmetry is a vertical line that divides the parabola into two equal halves.

In this instance, because the vertex is (0, 0), the axis of symmetry is x = 0

Directrix:

The directrix is the point that is an equally far from the vertex as the focus is. Because this is the case, it would be the opposite of the focus, making the directrix -\frac{1}{16}

Solution:

The only solution is x = 0 because the parabola only touches the x-axis once at the vertex

In a doctor's waiting room, there are 14 seats in a row. Eight people are waiting to be seated. There is someone with a very bad
diamong [38]

Answer: 12,972,960

Step-by-step explanation: There are 14 chairs and  8 people to be seated. But among the 8. three will be seated together:

So 5 people and (3) could be considered as 6 entities:

Since the order matters, we have to use permutation:

¹⁴P₆ = (14!)/(14-6)! = 2,162,160, But the family composed of 3 people can permute among them in 3! ways or 6 ways. So the total number of permutation will be ¹⁴P₆  x 3! 

2,162,160 x 6 = 12,972,960 ways.

Another way to solve this problem is as follow:

5 + (3) people are considered (for the time being) as 6 entities:

The 1st has a choice among 14 ways

The 2nd has a choice among 13 ways

The 3rd has a choice among 12 ways

The 4th has a choice among 11 ways

The 5th has a choice among 10 ways

The 6th has a choice among 9ways

So far there are 14x13x12x11x10x9 = 2,162,160 ways

But the 3 (that formed one group) could seat among themselves in 3!

or 6 ways:

Total number of permutation = 2,162,160 x 6 = 12,972,960
