Question

Use complete sentences to explain how you would use graphing technology to find the solutions of 0 = 2x2 − 3x + 0.5. What do the solutions of 0 = 2x2 − 3x + 0.5 represent on the graph of the equation?

My Answer:
Personally, I would use a graphing technology to find where the function f(x) = 2x^2 - 3x + 0.5 intersects the x-axis. The solutions of 0 = 2x^2 - 3x + 0.5 represent the x-intercepts of the graph.

Does this sound okay?

Answer 1

I have five more questions in this link that I wanted to get checked as well, is anyone is willing to take the time? http://answers.yahoo.com/question/index;_ylt=AmzVCpuDoLIuLXes5vZLu7jsy6IX;_ylv=3?qid=20120406181758AAkH1v9

Answer 2

They are all word problems, so they may take time... depending on how good you are in math. I just want to make sure my answers are correct.

Answer 3

sorry if it's to much

Answer 4

Use complete sentences to explain how you would use graphing technology to find the solutions of 0 = 2x^2 − 3x + 0.5.

I would plot the function and see where the graph hits the x axis . That points are soloutins

Answer 5

oh, you answered it , and it is like my answer;

Answer 6

yeah, I just need someone to check my answers, I already answered them :)

Answer 7

I can do that

Answer 8

yay!!

Answer 9

Answer 16

okay

Answer 17

that's funny, that was my original answer for that question, but then I guess I thought I did something wrong... thanks! :)

Answer 18

3 is right

Answer 19

These two I didn't post on yahoo only because I was pretty sure they were right, but while your here, no harm in checking right? :)

1. Alexei wants to hang a mirror in his boat but the mirror and frame must not have an area larger than 19.25 square feet. The mirror is 3 feet wide and 5 feet long. Which quadratic equation represents the area of the mirror and frame combined? (The border must have equal width on each side.)

2x2 + 8x − 19.25 = 0
3x2 + 5x − 19.25 = 0
4x2 + 16x − 4.25 = 0<---- My Answer
4x2 + 16x + 15 = 0

2. Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting height of the ball is 0 feet. Approximately what maximum height does the soccer ball reach?
