The following trigonometric equation is considered to be a trigonometric identity.

cos (x°) = sin (90 - x°)

Using complete sentences, explain why an infinite number of x values that will prove the trigonometric identity to be true.

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5)

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

For each polynomial, determine the degree and write the polynomial in descending order. a. –4x^2 – 12 + 11x^4 b. 2x^5 + 14 – 3x^4 + 7x + 3x^3
