> Question 2 of 16 5л Find an equation of the tangent line to f(x) = 4 sec (x) at x = 6 (Express numbers in exact form. Use symbolic notation and fractions where needed. Express equation in terms of y and x, where y is the dependent variable and x is the independent variable.) equation:

Assume that all variables represent real numbers. Determine whether each equation determines y to be a function of x. x=|y|

The resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?
