What is the axis of symmetry?
The axis of symmetry is a straight line that makes the shape of the object symmetrical. It can be either horizontal, vertical, or lateral. If we fold and unfold an object along the axis of symmetry, the two sides are identical.

A new city has an initial population of 600 and is doubling every hour. The new city reaches a population of 19,200 people. Which equation could represent the situation described and how long does it take for the population to reach 19,200?
a) 600(2)x=19,200 after 16 hours b) 2x+600=1900 after 7,750
c) 600(2)x=19,200 after 5 hours d) 2x+600=19200 after 8,250 hours
The correct answer choose is c) 600(2)x=19,200 after 5 hours
You can input the hours as the "x" value into each equations to determine is the value = 19,200

Erin was pushed just one on a swing. Erin movers a distance of 20 feet the first swing, and then only 80% as much as the previous swing for each after. Which of the following sequences express the distance Erin travels "n" swings after the first?
a) an=(20.88)n b) an=(20.80)n c) an=20(0.80)n d) a=20(0.80)n
The correct answer is c) an=20(0.80)n
20= is the a1
80% is the rate and in this case is the base because there is no other push after the first one.
