Answer:

Vertex=(0.5,9)

Axis-of-symmetry=0.5

<u>Skills needed: Quadratic Graphing</u>

Step-by-step explanation:

1) We need to first understand what the vertex is. In a parabola, the vertex is either the highest or lowest point. If the parabola is like a mountain (with the peak at the top), then it is the highest point. If the parabola is like a valley (with a divot like point at the lowest part), then the vertex is the lowest point.

---> On the graph in the picture, it is like a mountain.

- This mean it is the highest point for this graph.

The highest point would be (0.5, 9), as to the left of that point it goes down, and also to the right of the point it starts going down.

(0.5, 9) is the vertex.

2) The axis-of-symmetry is always the x-axis value of the vertex when given a parabola. This is basically the x-axis value for which the equation can be folded over with symmetry.

---> Axis of symmetry here is 0.5

A group of friends wants to go to the amusement park. They have $116 to spend on parking and admission. Parking is $10.25, and t
Alexus [3.1K]

Answer:

2 people

Step-by-step explanation:

no. of people = x

total parking costs = 10.25x

total tickets cost = 35.25x

total = 10.25x + 35.25x

suppose 3 people go, then the total cost will be

10.25(3) + 35.25(3) = 136.5 and this is greater than 116

Suppose 2 people go then the cost will be

10.25(2) + 35.25(2) = 91 which is less than 116

so only 2 people can go.

6. If you draw 35 lines on a piece of paper so that no two lines are parallel to each
umka2103 [35]

The point of intersection is the point where lines intersect.

<em>There will be 595 intersections for 35 lines, where no 3 lines are concurrent.</em>

<em />

Given

<em />n = 35<em> --- the number of lines</em>

<em />d = 3<em> --- no three lines are concurrent</em>

<em />

When no three line are concurrent, it means that no three lines meet at the same point.

<u>So, the sequence of intersection is:</u>

  • <em>0 intersection for 1 line</em>
  • <em>1 intersection for 2 lines</em>
  • <em>3 intersections for 3 lines</em>
  • <em>6 intersections for 4 lines</em>

<em />

Following the above sequence, the number of intersections for n lines is:

n_k = \frac{n \times (n - 1)}{2}

In this case, n = 35.

So, we have:

n_k = \frac{35 \times (35 - 1)}{2}

n_k = \frac{35 \times 34}{2}

n_k = 35 \times 17

n_k = 595

<em>Hence, there will be 595 intersections for 35 lines, where no 3 lines are concurrent.</em>

<em />
