Ashley is a member of the Movie-a-Month Club, where she rents movies each month. She uses the table below to keep track of the number of movies she rents and the total cost, which includes her monthly membership fee. Number of Movies vs. Total Cost
Number of Movies
12
15
9
22
Total Cost
$35.00
$42.50
$27.50
$60.00
Ashley graphed the relationship in the table. What is the slope of the graph, and what does it represent?
The slope of the graph is 2.50, and it represents the cost of each movie.
The slope of the graph is 2.50, and it represents the amount of the membership fee.
The slope of the graph is 5, and it represents the cost of each movie.
The slope of the graph is 5, and it represents the cost of the membership fee.
im not sure how to format it but its suppose to be a table.

# of movies Total Cost
9 27.50
12 35.00
15 42.50
22 60.00
Run or change in x: 9 - 22 = -13
Rise or change in y: 27.50 - 60 = -32.50
Slope = Rise / Run
Slope = -32.50 / -13
Slope = 2.50
The slope is 2.50, and it represents the cost of each movie.

Area of the shade region=area of the square - area of a circle
1)we calculate the area of the square.
area of a square =slide²
slide=8 m
area of a square=(8 m)²=64 m².
2) we calculate the area of the circle:
area of a circle=πr²
r=4 m
area of a circle=π(4 m)²=16π m²≈50.27 m²
3) we calculate the area of the shaded region:
Area of the shaded region=64 m² - 50.27 m²=13.73 m²
answer:The area of the shaded regios is 13.73 m²

Answers
Answer:
Step-by-step explanation:
The given y=x²+4x+3 should be re-written in "vertex form," which is
y = a(x - h) + k, where (h, k) is the vertex.
Here y=x²+4x+3 = y=x²+4x + 4 - 4 +3 (completing the square), or
y = x^2 + 4x + 4 - 1. which condenses to y = (x + 2)^2 - 1
Thus, h = -2 and k = 1, and so the vertex is at (h, k), or (-2, 1). This parabola opens up. The axis of symmetry is the vertical line x = -2.
An alternative equation for a vertical parabola that opens up is:
y - k = 4p(x - h)^2. Rewriting y = (x + 2)^2 - 1 to fit this form leads to:
y + 1 = 4p(x + 2)^2. We must find the value of p that makes this equation true at any (x, y) on the graph. Suppose we arbitrarily choose x = 1. Then, according to y=x²+4x+3, y = 1^2 + 4(1) + 3, or y = 8 when x = 1.
Then y - k = 4p(x - h)^2 becomes 8 - 1 = 4p(1 + 2)^2, or
7 = 4p(9), or p = 7/36
The focus is thus 7/36 units above the vertex: (-2 + 7/36), and the directrix is the horizontal line which is 7/36 units below the vertex: y = -2 - 7/36.
Vertex: (-2, 1)
Focus: (-2, 2 7/36)
Directrix: y = -2 7/36

If you graph it you can see that they all the points match up to the perfect right triangle. You may have to rotate it to see it though. Point Z is the angle of the triangle that is the corner of the 90 degree triangle.

2.5 * x - 10.5 = 64 * 0.5 * x
2.5 * x - 10.5 = 32 * x
- 10.5 = 32 * x - 2.5 * x
- 10.5 = 29.5 * x
x = - 10.5 / 29.5
