    Important information about Capacitive Reactance

    Capacitive reactance X_c in an electrical circuit to an alternating current is given by: (Please see attached) where f is frequency of the current and C is capacitance of the circuit. Solve for f.

    Rate of Rainfall

    Two rainstorms occurred in one week in a certain area. The first storm lasted 25 hours, and the second storm lasted 35 hours, for a total 2050ml of rain. What was the rate of rainfall for each of the two storms if the sum of the two rates was 70ml per hour?

    Graphing an Inequality Slope

    For inequality, 3x - 2y < 7 a) What is the slope? b) What is the y-intercept? c) Is the line dashed or solid? d) Is the area shaded below or above the line? e) Which Quadrant(s) is the area shaded: I, II, III, IV? f) Is (1,-3) the solution to the inequality?

    Growth rate of an exponential function

    In everyday language, exponential growth means very fasy growth. In this problem, you will see that any exponentially growing function eventually grows faster than any power function. (a) Show that the relative growth rate of the function f(x) = x^n, for fixed n>0 and for x>0, decreases as x increases. (b) Assume k>0 is f

    Writing Equations from Word Problems

    74. An algebraic equation is a complete sentence. It has a subject, a verb, and a predicate. For example, x + 2 = 5 can be written in English as "Two more than a number is five." Or. "A number added to two is five." Write an English version of the following equations. Be sure you write complete sentences and that the sentences e
