The village green is the shape of a square. Along the diagonal of the square is a path through the park. The path is 80 feet long. Find the area of the park. Round to the nearest tenth, if necessary.

1. If a person invests in a tax-sheltered annuity, the money invested, as well as the interest earned, is not subject to taxation until withdrawn from the account. Assume that a person invests $2000 each year in a tax-sheltered annuity at 10 percent interest compounded annually. Let An represent the amount at the end of n year

Let (f_k) be the Fibonacci sequence, show that: a) For every integer n>= 0, we have f_4(n+1) = 3f_4n+1 + 2f_4n b) Use a) in order to prove by induction that ∀n Є N, 3 | f_4n

A pilot flies from Toledo to Chicago, which lies 280 mi directly west. Her plane can fly at 120 mi/hr. She ignores the wind and heads directly west. However, there is a 25 mi/hr wind blowing from the south. a) Write the equation that describes the effect of the wind b) Write the equation that describes the plane's contr

Let G be a nonabelian group and Z(G) be its center. Show that the factor group G/Z(G) is not a cyclic group. We know if G is abelian, Z(G)=G. But now if it is not abelian, can we simply say because G is not cyclic, then any factor group will not be cyclic either? or is there more to it?

Fibonacci posed the following problem: Suppose that rabbits live forever and that every month each pair produces a new pair which becomes productive at age 2 months. If we start with one newborn pair, how many pairs of rabbits will we have in the nth month? Show that the answer is fn, where {fn} is the Fibonacci sequence defined
