Answer:
The ratio would be 39:100.
Step-by-step explanation:
Check the picture below.
that's the line of x = 12, just a straight vertical line, notice the green line, that's parallel to it, and the red line, that's perpendicular to it.
let's pick two points for each to get their slopes, hmm say for the green one (5,2) and (5,4)
and for the red one hmmm (3,2) and (7,2)
1.Make a table with the x,y coordinates of each vertex. Start at any vertex and go around the polygon in either direction. Add the starting vertex again at the end. You should get a table that looks like the leftmost gray box in the figure above.
2.Combine the first two rows by:
Multiplying the first row x by the second row y. (red)
Multiplying the first row y by the second row x (blue)
Subtract the second product form the first.
3.Repeat this for rows 2 and 3, then rows 3 and 4 and so on.
4.Add these results, make it positive if required, and divide by two.
It’s really simple if you think about it
Answer:
Step-by-step explanation:
Domain: - ∞ <x < ∞
Range: The range starts out at - ∞ and goes to 8
- ∞ < y ≤ 8
Vertex: (0,8) The vertex is a point. It's the highest point.
Axis of symmetry: x = 0 The axis of symmetry is the y axis.
zeros: (4,0) and (-4,0)
I have no idea what the last sentence is asking for.
