In $a x^2+b x+c=0$, the equation has the solution $x=0$. What does this tell you about the parameters? Assume $a \neq$ 0.

The widely used solvent ethyl acetate undergoes the following reaction in basic solution:

$$\mathrm{CH}_3 \mathrm{CO}_2 \mathrm{C}_2 \mathrm{H}_5(a q)+\mathrm{OH}^{-}(a q) \longrightarrow \mathrm{CH}_3 \mathrm{CO}_2^{-}(a q)+\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}(a q)$$

The rate of this reaction increases by a factor of $6.37$ on raising the temperature from $15^{\circ} \mathrm{C}$ to $45^{\circ} \mathrm{C}$. Calculate the value of the activation energy in $\mathrm{kJ} / \mathrm{mol}$.

If you buy a lottery ticket in 50 lotteries, in each of which your chance of winning a prize is $\frac{1}{100}$, what is the (approximate) probability that you will win a prize (a) at least once, (b) exactly once, (c) at least twice?

Perform the following steps to find the maximum area of the rectangle shown in the figure.

a. Solve for $c$ in the equation $f(c)=f(c+x)$.

b. Use the result in part (a) to write the area $A$ as a function of $x$. [Hint: $A=x f(c)]$

c. Use a graphing utility to graph $A$. Use the graph to approximate the dimensions of the rectangle of maximum area. Determine the required area.

d. Use a graphing utility to graph the expression for $c$ found in part (a). Use the graph to approximate $\lim _{x \rightarrow 0^{+}} c$ and $\lim _{x \rightarrow \infty} c$. Use this result to describe the changes in the dimensions and position of the rectangle for $0<x<\infty$.
