C. p. 1 if z = f(a(s, t), b(s, t)) = in a cos with a(s, t) = 28 +t and b(s, t) = 8 - 2t, find the first derivatives of z with respect to the independent variables s and t. c. p. 2 if w = f(s, t) with 8 = 8(x, y,z, p) and t = (x, y, z, p), write chain rule expressions for all possible first derivatives of w with respect to the four independent variables.

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

Match the vocabulary to the proper definition. in probability, two events in which 1. conditional probability the outcome of one event is independent of the outcome of a second event. 2. dependent events in probability, two events in which the outcome of one event is dependent on the outcome of a second event. the probability of an event in which the outcome of the event is conditional on the outcome of one or more different events. 3. independent events

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle?
