If a 25 foot tree casts a 56 foot shadow, what is the angle that the sun is hitting the tree?

(Draw your image!) Tan x = Opposite / Hypotenuse Tan x = 56/25 Tan x = 2.24 x = 65.9 degrees

What is plagiarism, and why is proper citation important?

Plagiarism is the act of using another person's words or thoughts and failing to give proper credit. Plagiarism can be intentional (using someone else's paper or copying large paragraphs of text into your paper) or unintentional (forgetting to cite a work or using wording that is too close to the original). It is important to properly cite your sources for several reasons: 1) Citation acknowledges the work of others 2) Citation demonstrates the reliability of your research 3) Citation provides background to your research 4) Citation allows your readers to continue reading about your subject

Solve for x. x^2 + 2x + 25 = 11x + 5

x^2 + 2x + 25 = 11x + 5 (Original equation) x^2 - 9x +20 = 0 (Set the equation to zero by subrtacting 11x+5 from both sides) (x-5)(x-4) = 0 (Factor the quadratic) x-5 = 0 OR x-4 = 0 (Zero Product Property) x = 5 OR x = 4 (Solve each equation for x) x = (5, 4) (Final Answer)
