Plz the statement "cot theta= 12/15, sec theta= -13/5 and the terminal point determined by theta is in quadrant 4": a. cannot be true because sec(theta) is greater than zero in quadrant 4 b. cannot be true because if cot(theta)= -12/5, then sec(theta)= +/- 13/12. c. cannot be true because cot(theta) must be less than 1. d. cannot be true because 12^2+5^2 does not = 1.

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ac=26 and ch=8, find bh.

Question 6(multiple choice worth 5 points) (05.02 lc) what is the value of x? a right angle is shown divided into two parts. the measure of one part of the right angle is 10 degrees. the measure of the other part is 2x 20 40 45 85
