When the dilation of a line or is centered at the origin,
both the x and y coordinates are multiplied by the same value, k (which
represents the scale or ratio of dilation)
If ab is dilated by a factor of 2/5 to produce a’b’, then k
= 2/5
Since the dilation is centered at origin,
The y-coordinate of b' what will be 2/5 of the y-coordinate of b.
Answer:
432 feet
Step-by-step explanation:
The total length of line he will draw is equivalent to the perimeter of the plane shape he is drawing. Given that it is a soccer field measured as 96 feet by 120 feet, the shape is a rectangle.
The perimeter p of a rectangle whose length is l and width is b is given as
p = 2(l+b)
Hence the length of the line he must draw
= 2(96 + 120)
= 2 * 216
= 432 feet
Answer:
b)On the scatter plot of the data, there are some points above and below the regression line, but no points that fall on the line.
c)The line is not a good fit for the data.
f)The residuals are relatively small compared to the actual data values.

Answer:
D
Step-by-step explanation:
First take out a factor of 2:
2(1 - 25x^2)
Then factor the difference of squares:
2(1 -5x)(1+5x)
