In your post, include the height, the width, and the calculations needed to determine the length of the diagonal of your computer monitor. After you have calculated the approximate length using the Pythagorean theorem, use a measuring device to measure the length of the diagonal of your monitor. Was your measurement close? Why might the measurements not be exactly the same?
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 ballís 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

ok 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.

Sure. 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.

this 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
