Answer: B
Picture 1 shows the reflection of ABC 180° clockwise about the origin. To draw A'B'C' we draw the line segments AO, BO, and CO and extend them such that O is the midpoint of line segments AA', BB', and CC' respectively.
Picture 2 shows the line y=-x (the yellow line.) This is the line containing all points of the form (x, -x), that is, this points contains (1, -1), (-2, 2) etc...
We see that point C' is already on this line, and we draw the reflections of points B and C with respect to this line, to find B'' and C'' with coordinates as shown in the figure.
Answer:
Common ratio is 3
The three terms are 162, 486, 1458
Step-by-step explanation:
Given: The first 4 terms of a sequence are
To find:
A. the common ratio
B. the next 3 values in the geometric sequence
Solution:
Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.
A.
So, the common ratio is
B.
The next three values are as follows:
Answer:
The number 5 multiplied by -1 then by 2 then by -3 then by 4....... (alternating positive and negative
Step-by-step explanation:
5*-1 = -5
5*2 = 10
5*-3= -15
5*4= 20
5*-5 = -25 ......
Perpendicular = opposite sign and reciprocal slope
4/5x slope turns into -5/4x
The slope of perpendicular line: -5/4x
The answer is A).
0.14/0.2
=0.7
