Which expression you find the length x of a side of a rectangle that has a diagonal of 15 units and a width of 9 units? a x^2 = 15^2 – 9^2 b x^2 = (15 + 9)^2 c x^2 = 15^2 + 9^2 d x^2 = (15 – 9)^2

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

The number of nails of a given length is normally distributed with a mean length of 5.00 in, and a standard deviation of 0.03 in. find the number of nails in a bag of 120 that are less than 4.94 in. long.
