1. Solve for x. 1.1 343x = 492x+3 1.2 log2 (5x - 2) + log1/2 (x + 3) = 0 1.3 x = log1/2(1/4) log1/4(1/8) log1/8(1/16) 2. Answer the following with respect to the tangent line. 2.1 Determine the tangent line to x2 + y2 = 100 at x = 6 2.2 Determine the coordinate where the function's value and the slope of its tangent line are equal given f(x) = x2 - 4 x - 2 2.3 Determine the equation of the tangent line to x2 + xy + y2 = 12 at x = 2 3. Determine the definite integral. 3.1 fIn(x) /x dx; x > 0; F(e) = 1 3.2 S1/(1+5e-x) dx; F(-co) = In(5) 3.3 f 2.5 In(2) (25vx) / Vx dx; x > 0; F(1/25) = 2
