405/5=81 rotations per minute
405/60 seconds times 5 minutes=405/300=1 7/20 rotations per second
Answer:
- -1/3
- not geometric
- -5
- 4
Step-by-step explanation:
You find the ratio of terms by dividing the second by the first. If the ratio is the same for all adjacent pairs of terms, it is a "common" ratio.
1) (2/3)/-2 = -1/3
(-2/9)/(2/3) = -1/3
(2/27)/(-2/9) = -1/3 . . . . . the common ratio is -1/3
___
2) 2/0 = undefined . . . . not a geometric sequence
___
3) -10/2 = -5
50/-10 = -5
-250/50 = -5 . . . . . the common ratio is -5
___
4) 4/1 = 4
16/4 = 4
64/16 = 4 . . . . . the common ratio is 4
Answer:
a) ΔF'G'H' is the image of ΔFGH
b)Center of dilation (7,-1)
c) Scale factor: 
Step-by-step explanation:
Question a
Since the smaller triangle is named F'G'H', it means that, it is the image of triangle FGH.
Question B.
To find the center of dilation, draw straight lines through any two corresponding points.
The straight lines will meet at (7,-1).
This is called the center of dilation.
See graph in attachment.
Question c
The scale factor of the dilation is given by;
