[Jawaban] A student wants to find point $C$ on the directed line segment from $A$ to $B$ on a number line such that the segment is partitioned in a ratio of $3: 4$. Point $A$ is at -6 and point $B$ is at 2. The student's work is shown. 1. $C=\left(\frac{3}{4}\right)(2-(-6))+(-6)$ 2. $C=\left(\frac{3}{4}\right)(8)-6$ 3. $c=6-6$ 4. $C =0$ Analyze the student's work. Is the answer correct? Explain. A. No, the student should have added $3+4$ to get the total number of sections, and used the fraction $\frac{3}{7}$ instead of $\frac{3}{4}$. B. No, the student should have subtracted 2 from -6 to find the distance. C. No, the student should have added 2 at the end to add to the starting point. D. Yes, the student's answer is correct.

[Jawaban] Analyzing Text Structure I don't think any segregation law angered black people in Montgomery more than bus segregation. And that had been so since the laws about segregation on public transportation had been passed. That was back in 1900, and black people had boycotted Montgomery streetcars until the City Council changed its ordinance so that nobody would be forced to give up a seat unless there was another seat to move to. But over the years practices had changed, although the law had not. -My Story, Rosa Parks What does this type of text structure highlight? What is the cause? What is the effect?

[Jawaban] Given this matrix, perform the RREF operation on a calculator to find the solutions to the nearest hundredth. $\left[\begin{array}{ccc} 100 & -1 & -200 \ 75 & 1 & 2,000 \end{array}\right]$ In $\square$ months, Rafiki will be able to pay off the remaining balance of $\$\square$

[Jawaban] Solve the equation, writing the solution as a reduced fraction or as an integer. If there is no real solution, enter "DNE." If there are multiple solutions, separate the solutions with a comma. Solve: [tex]$\sqrt{-3 l-6}=5$[/tex] Solution: [tex]$l=$[/tex] $\square$

[Jawaban] The possible rational roots are [tex]\pm 1, \pm 3, \pm 5, \pm 9, \pm 15[/tex], and [tex]\pm 45[/tex]. The actual roots ordered from least to greatest are [$\square$] and [$\square$].

[Jawaban] Select the correct answer. Consider functions [tex]$f$[/tex] and [tex]$g$[/tex]. [tex] \begin{array}{l} f(x)=x^4-16 x^3+94 x^2-240 x+225 \\ g(x)=\frac{1}{x-4}-1 \end{array} [/tex] Using graphing, what is the solution, or solutions, of [tex]$f(x)=g(x)$[/tex]? A. [tex]$x=0 ; x=5$[/tex] B. [tex]$x=3$[/tex] C. [tex]$x=0 ; x=3$[/tex] D. [tex]$x=5$[/tex]

[Jawaban] Given a function value of an acute angle, find the other five trigonometric function values. $\csc \theta=2.6$ $\sin \theta \approx 0.38 \quad \cos \theta \approx 0.92 \quad \tan \theta \approx 0.42$ (Round to two decimal places as needed.) $\sec \theta \approx \square \cot \theta \approx \square$ (Round to two decimal places as needed.)

[Jawaban] Simplify the expression. [tex]\left(\frac{4}{3}\right)^{-2}=\frac{3^2}{4^2}[/tex]
