Two word problems on Present Value
1. Income from a precious metals mining operation has been decreasing uniformly for 5 years. If income in year 1 was $100,000 and it decreased by $10,000 per year through year 5, the present worth of the income at 10% per year is closest to? A. $310,500 B. $352,200 C. $379,100 2. Income from sales of a certain oil additi ...continues
A thin glass pipe with the internal diameter of 3 mm was probed into a heart tissue (membrane) and air pressure was plied thriugh the pipe to expand the membrane. Assuming its thickness to be negligible, the circular arc of the bulged membrane was to be 3.6mm (see picture below). Find the volume of the excessive space between th ...continues
Prove a theorem relating to complex solutions of a polynomial eqn
(See attached file for full problem description and equations) --- Prove that if p is a polynomial with real coefficients, and if is a (complex) solution of P(E)z = 0, then the conjugate of z, the real part of z, and the imaginary part of z are also solutions. Note: This is from a numerical analysis course, and here P(E) ...continues

(See attached file for full problem description and equations) --- 1. Let g : R → R+ be such a function that g ∈ C1(R) and for all x ∈ R,−1 < g'(x) < 0. Show that the sequence xn+1 := g(xn) converges to the unique fixed point of the function g, regardless of choice of x0 ∈ R. [Note: Observe t ...continues
