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. )
