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).
Answer:
y=8x
Step-by-step explanation:
the slope is 8/1 you times x by the slope and the y intercept is 0 so you don't add anything to 8x
33100 = 7.8% of total
33100 = .078 x total (change from percent to decimal)
33100/.078 = total (divide both sides by decimal)
424358.9 = total
Round to 424,359 copies.
Answer: $4.5/hour
Step-by-step explanation:
Total earned in 6 hours subtracted tips equals wage over 6 hours.
Divide by 6 hours to find individual hourly wage.
In this case, we must use trigonometry to find the value of x:

Thus the value of x rounded to the nearest tenth is <u>8.2</u>
