At the beginning of the day stock xyz opened at 3.15. at the end of the day it closed at 2.87. what is the rate of change of stock xyz. a) 4.1% b) -8.9% c) 9.8% d) -0.09%

The correct answer is B) -8.9%

The rate of change for any problem is always determined using the following equation.

In this case, the old value is 3.15 and the new value is 2.87. SO we use these in the equation to get the answer.

-.088889 * 100

-8.9%

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
