Problem 2. An evaluation of diffusion bonding of zircaloy components is performed. The main objective is to determine whether at least one any of the three elements -nickel, iron or copper- produces a different bonding effect. A series of zircaloy components are bonded using each of the bonding agents. Since there is a significant amount of variation among components machined from different ingots, a randomized block design is used, blocking on the ingots. A pair of components from each ingot is bonded together, using each of the three agents, and the pressure (in units of 1000 psi) required to separate the bonded components is measured. The data is shown below.

(1 point) The solution of a certain differential equation is of the form \begin{align*} y(t) = a e^{4t} + b e^{5t}, \end{align*} where $a$ and $b$ are constants. The solution has initial conditions $y(0) = 5$ and $y'(0) = 2$. Find the solution by using the initial conditions to get linear equations for $a$ and $b$. \begin{align*} y(t) = 23e^{4t} - 18e^{5t} \end{align*}
