The answers should be 4.5 feet
C) I think you know the increasing line is the one with 3*x and the other one is -2*x, then the dotted line requires <, instead of <=, the rest I'm sure you can figure out.
Let me know if you need more explanation, but it's to make sure next time you answer someone, instead of asking! :)
A pentagon has five sides
Answer:
2.22m/s
Step-by-step explanation:
Distance = Velocity/Time
533.33m = V/4minutes
V = 533.33/240 seconds
V = 2.22m/s
Answer:
C (x, y) -> (x + 7, y + 8); scale factor = 3
Step-by-step explanation:
The translation can be found by subtracting the coordinates of the original center from those of the center of the image. The scale factor will be the ratio of the radii.
__
<h3>translation</h3>
We note the center coordinates are I(-3, -6) and I'(4, 2). Then the translation is ...
I' -I = (4, 2) -(-3, -6) = (4 +3, 2 +6) = (7, 8)
(x, y) ⇒ (x +7, y +8)
<h3>scale factor</h3>
The radius of each circle can be found by counting the grid squares from the center to the circle. It works best to do this along a horizontal or vertical line.
The radius of circle I is 2; the radius of circle I' is 6. The scale factor is ...
scale factor = 6/2 = 3
