Answer: (9,5) and 2
Step-by-step explanation:
Get the difference between the coordinate points (9,5)
Multiply by 2
Answer:
y = x^2 - 4
Step-by-step explanation:
The vertex of a parabola is exactly halfway between the focus and the directrix. If the focus is at (0, -6) and the directrix is the line y = -2, then we do this to locate the vertex: Draw a vertical line through (0, -6) also crossing the line y = -2. The y value halfway between y = -6 and y = -2 is y = -4, and the vertex is thus (0, -4).
Using the vertex method, write out the equation of this parabola, starting with the general form y - k = (x-h)^2, where (h, k) is the vertex. Here h = 0 and k = -4
We get: y + 4 = (x - 0)^2, or y + 4 = x^2, or y = x^2 - 4. As a check, let x = 0; y = -4, which is the y-coordinate of the vertex.
The correct answer is actually (a) because rate of change is x/y (or that's how I learned it) then the more big the slope the bigger the rate of change
Answer:
(-20x -40)
Step-by-step explanation:
Answer:
3,456 pictures
Step-by-step explanation:
It can take 72 pictures in an hour. (3600 seconds in an hour ÷ 50 seconds)
72 × 48 = 3456 photos
