ALGEBRA: 8.3.2 Problem 8-105


The Background...

Riding Up and Visiting:

More Details...
The Saint Louis Gateway Arch has a shape much like a (1)___________________.  Suppose the x and y represent distances in feet and the origin is the point on the ground directly below the arch's apex.

The Task...

Write the formula in standard form (2) ____________________ and find the vertex (3) ______________
of the arch.  Along with that, find the y intercept (4)____________________ and both of the x intercepts        
(5)_______________________     (6)_________________________.

Algebra 8-84 b

1. Find x intercepts
2. Set them to Zero using Zero Product Property.
3. Find the factored quantities.
4. Insert your x coordinate from the height into your factored quantities. Both should equal the same number.
5. The number obtained after subtracting is the GCF that needs to be outside of the two quantities.


PreAlgebra: Chapter 7 Questions 6 and 7!

Question 6:  Overstock dot com has forgotten to indicate the "You Save" part on their website for this hammock.  What is the the percent of decrease that you will obtain, when a person purchases this item?  Place your work on the back of your quiz.  *Don't forget to submit your answer!

Question 7:  Below are two signs indicating gas prices.  WE WILL FOCUS ON THE TOP LINE ONLY! DON'T worry about the fractions.  Focus on the main dollars and cents!
The EXXON sign is from the 1970's.  The SHELL sign is from today.  Determine the percent gas has increased!  Show your work on the back of your quiz.  *Don't forget to submit your answer.

That is $3.98 (three dollars and 98 cents)

To help in mastering this concept, please complete the problems found on THIS LINK.

HINT:  To find the VERTEX, find the LINE OF SYMMETRY (the exact 1/2 way point on the x-axis) in the parabola.  Insert that x axis point into your original equation and you will find the y.  This y becomes your vertex point!
