● Complete the Section 6-1 Entrance Ticket.
○ You may use your notes and/or Section 6-1
handout, but you MUST work by yourself.
○ This will count as a quiz grade.
○ You may use a calculator, but DO NOT simply plug
the numbers into your calculator. You need to show
work, such as factor trees, to receive full credit.
● When you are finished, raise your hand, and I will
collect your paper.
Simplify the following expressions.

Rationalizing the Denominator
Dividing Rational Expressions
When simplifying radical expressions, we sometimes end
up with a radical in the denominator. We must then
rationalize the denominator.
Divide and simplify. Rationalize the denominator if
necessary.

Applying Radical Quotients
The formula
shows the time t that any vehicle takes to
travel a distance s at a constant acceleration a, starting from
rest.
1. What is the time that a car accelerating at 16 m/s2 takes to
travel 200 m?
2. What is the time that a car accelerating at 25 m/s2 takes to
travel 200 m?
3. What is the difference in time between a car accelerating at
16m/s2 and one accelerating at 25 m/s2 for a distance of 200 m?
