I need to find the upper asymptotic bound for the recursion: T(k)=2T(k-1)+1/k; I was able to determine: (1) The height of this tree is k-1; (2) The cost of each level is (2i)/(k-i)

If two angles of two triangles are congruent to each other, then the third angles will be congruent to each other. Using the above statement, choose which two congruency criteria eventually becomes same.
A)SAS and ASA;
B)AAS and SAS;
C)AAS and ASA;
D) No two congruency criteria are same

Evaluate $6C_3$

Solve the following differential equation dx/dy=-[(4y2+6xy)/(3y2+2x)]

The velocity distribution for laminar flow between parallel plates is given by:
$\frac{u}{u_{max}}=1-<!--\; -\; -->{\left(\frac{2y}{h}\right)}^2$
where h is the distance separating the plates and the origin is placed midway between the plates. Consider a flow of water at ${15}^{\circ <!--\; \circ \; -->}C$ , with $u_{max}=0.30\frac{m}{sec}$ and $h=0.50mm$ . Calculate the shear stress on the upper plate and give its direction.

In August 2013, E*TRADE Financial was offering only 0.05% interest on its online checking accounts, with interest reinvested monthly. Find the associated exponential model for the value of a $5000 deposit after "t" years. Assuming that this rate of return continued for 7 years, how much would a deposit of $5000 in August 2013 be worth in August 2020? (Answer to the nearest $1. )
