a square with a side length of 2 units is drawn on the coordinate plane with a vertex at the origin. Which shows a dilation of the square by a scale factor of 2

Step-by-step explanation:

From the figure attached,

ABCD is a square with vertices as,

A(-2, 0), B(-2, 2), C(0, 2) and D(0, 0)

If the given square is dilated by a scale factor of 2 and the center of dilation is the point D (origin).

Rule for the dilation of a point by a scale factor k is,

(x, y) → (kx, ky)

By this rule,

A(-2, 0) → A'(-4, 0)

B(-2, 2) → B'(-4, 4)

C(0, 2) → C'(0, 4)

D(0, 0) → D'(0, 0)

Now we can plot these points to get the image square (dilated figure) as given the figure attached.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
