Given:
The coordinates of point A are (7,4).
It is dilated from the origin by a scale factor r = 3.
To find:
The coordinates of A'.
Solution:
If a figure is dilated from the origin by a scale factor k, then

Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:

Using this rule, we get


Therefore, the coordinates of point A' are (21,12).
A lot of the people out there are saying that the answer is negative 2 over sqrt 29. However, I am doing the test, and if you multiply the top and bottom by sqrt of 29, you get D, which is -2 sqrt29/29
D. I think. Hope that helps
Answer:
The 25th term of the sequence is 147
Step-by-step explanation:
For an nth term in an arithmetic sequence
U(n) = a + (n - 1)d
Where
n is the number of terms
a is the first term
d is the common difference
From the above sequence
a = 3
d = 9 - 3 = 6
So the 25th terms for the sequence is
U(25) = 3 + ( 25 - 1) 6
= 3 + 24(6)
= 3 + 144
The final answer is
= 147
Hope this helps you.
