Typing hint: Type Pythagorean theorem as a^2 + b^2 = c^2. Do not use special graphs or symbols because they will not appear when pasted to the discussion board.

Part 2: Using the Library, web resources, and/or other materials, find a real-life application of a quadratic function. State the application, give the equation of the quadratic function, and state what the x and y in the application represent. Choose at least two values of x to input into your function and find the corresponding y for each. State, in words, what each x and y means in terms of your real-life application. Please see the following example. Do not use any version of this example in your own post. You may use other variables besides x and y, such as t and S depicted in the following example, but you may not use that example. Be sure to reference all sources using APA style.

Typing hint: To type x-squared, use x^2. Do not use special graphs or symbols because they will not appear when pasted to the Discussion Board.

When thrown into the air from the top of a 50 ft building, a ball’s height, S, at time t can be found by S(t) = -16t^2 + 32t + 50. When t = 1, s = -16(1)^2 + 32(1) + 50 = 66. This implies that after 1 second, the height of the ball is 66 feet. When t = 2, s = -16(2)^2 + 32(2) + 50 = 50. This implies that after 2 seconds, the height of the ball is 50 feet.

my monitor is 13inch by 10inch

**Michael**, Thursday, November 22, 2007 at 10:45pmYour monitor is 13" by 10.5", and those are the height and width (a and b in the Pythagorean theorem).

a^2 + b^2 = c^2

Plug in a & b to solve for c.

**Patrick**, Thursday, November 22, 2007 at 11:16pmok thank you know if you could break it down to me where i can do it own my owe that would be great. because, i do not know how to do algebra at all.and i'm taking a college corse it which i have to pass.

**Michael**, Thursday, November 22, 2007 at 11:34pmSure. I'll give you an example of the Pythagorean Theorem.

We have a triangle with sides of 7 and 12. We need to find the hypotenuse (also called the diagonal).

a^2 + b^2 = c^2

Our sides are always a and b, and our hypotenuse is always c.

7^2 + 12^2 = c^2

49 + 144 = c^2

193 = c^2

Square root both sides of this because √(x^2) = x. The square root and the square cancel out.

√193 = √(c^2)

√193 = c

13.9 = c

If you have any more questions, let me know.

**Patrick**, Friday, November 23, 2007 at 11:16pmthis is what I came up with for my monitor is this right or did I do it wrong.

a^2 + b^2 = c^2

13*2+10*2 = c^2

26+20= c^2

46=c^2

46=√(c^2)

6.78= c
