Explain what is phlebitis.

Spiro says, "Choose a number. Multiply by 3. Subtract 2. Multiply by 5." For each starting number given, what is your ending number?
a. $n$
b. 4 c. $\dfrac{4}{3}$

What is phlebitis?

Do the equations $x-2=5$ and $\frac{x}{x-7}-\frac{2}{x-7}=\frac{5}{x-7}$ have the same solution(s)?

Apply a graphing utility to plot $y_1=1+x+x^2+x^3+x^4$ and $y_2=\frac{1}{1-x}$, and let the range of $x$ be $[-0.5,0.5]$. Based on what you see, what do you expect the geometric series $\sum_{n=0}^{\infty} x^n$ to sum to?

Apply a graphing utility to plot $y_1=1-x+x^2-x^3+x^4$ and $y_2=\frac{1}{1+x}$, and let $x$ range from $[-0.5,0.5]$. Based on what you see, what do you expect the geometric series $\sum_{n=0}^{\infty}(-1)^n x^n$ to sum to?

Suppose a graph similar to (Figure $19-9$ ) were drawn for the process $\mathrm{I}_2(\mathrm{~s}) \longrightarrow \mathrm{I}_2(1)$ at $1 \mathrm{~atm}$. What would be the value of $\Delta G^{\circ}$ at this temperature? Explain.

Calculate $\Delta H$ for the process $\mathrm{Hg}_{2} \mathrm{Cl}_{2}(s) \longrightarrow 2 \mathrm{Hg}(l)+\mathrm{Cl}_{2}(g)$ from the following information: $\mathrm{Hg}(l)+\mathrm{Cl}_{2}(g) \longrightarrow \mathrm{HgCl}_{2}(s)$ $\Delta H=-224 \mathrm{kJ}$ $\mathrm{Hg}(l)+\mathrm{HgCl}_{2}(s) \longrightarrow \mathrm{Hg}_{2} \mathrm{Cl}_{2}(s)$ $\Delta H=-41.2 \mathrm{kJ}$

Given $c=\langle 5,-12\rangle$ and $d=\langle 10,-24\rangle$, a. Find the product $\|c\|\|d\|$. b. Find $c \cdot d$. c. Based on the results of parts (a) and (b), what do you know about the two vectors?

Do the equations x - 2 = 5 and $\frac{x}{x-7}-\frac{2}{x-7}=\frac{5}{x-7}$ have the same solution(s)?

Do the following calculations, and write the answers in scientific notation:

$$\begin{array} { l } { \text { a. } 37000000 \mathrm { A } \times 7100000 \mathrm { s } } \\ { \text { b. } 0.000312 \mathrm { m } ^ { 3 } \div 486 \mathrm { s } } \end{array}$$

The question can be answered using the algebraic method or using a GDC. Make sure you can do both. s = t(35 + 6t) Find $\frac{\mathrm{d} s}{\mathrm{d} t}$ when t = 3.

Compute the following products. (a) $([a] \oplus [b])^2$ in $\mathbb{Z}_2$ (b) $([a] \oplus [b])^3$ in $\mathbb{Z}_3$ (c) $([a] \oplus [b])^5$ in $\mathbb{Z}_5$ (d) Based on the results of parts (a)-(c), what do you think $([a] \oplus [b])^7$ is equal to in $\mathbb{Z}_7$?

What does the equation $s=-16 t^{2}+v_{0} t+s_{0}$ represent? What do v0 and s0 represent?
