Let there be a rotation of 180 degrees about the origin. Point A has coordinates (-2,-4), and point B has coordinates (-3,1), as shown below.
8- (-3.1)

A(-2,-4)
1.
What are the coordinates of Rotation(A)? Mark that point on the graph so that Rotation(A) = A'. What are the
coordinates of Rotation(B)? Mark that point on the graph so that Rotation(B) = B'.

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
