[Jawaban] Consider the following reversible reaction. [tex]2 H_2 O(g) \leftrightarrow 2 H_2(g)+O_2(g)[/tex] What is the equilibrium constant expression for the given system? A. [tex]K _{ eq }=\frac{\left[ H _2 O \right]}{\left[ H _2\right]\left[ O _2\right]}[/tex] B. [tex]K _{ eq }=\frac{\left[ H _2 O \right]^2}{\left[ H _2\right]^2\left[ O _2\right]}[/tex] C. [tex]K _{ eq }=\frac{\left[ H _2\right]^2\left[ O _2\right]}{\left[ H _2 O \right]}[/tex] D. [tex]K _{ eq }=\frac{\left[ H _2\right]^2\left[ O _2\right]}{\left[ H _2 O \right]^2}[/tex]

[Jawaban] The overall cost of carpet and installation from a particular company is represented by the function, where [tex]$x$[/tex] represents the square footage of the carpet. [tex]$P(x)=\$ 2.35 x+\$ 104.00$[/tex] What is the average rate of change over the interval [tex]$[2,000,2,500]$[/tex]? A. [tex]$\$[/tex]0.43 per square foot B. [tex]$\$[/tex]4.81 per square foot C. [tex]$\$[/tex]2.35 per square foot D. [tex]$\$[/tex]1.04 per square foot

[Jawaban] Proof: We are given that [tex]$AB =12$[/tex] and [tex]$AC =6$[/tex]. Applying the segment addition property, we get [tex]$A C+C B=A B$[/tex]. Applying the substitution property, we get [tex]$6+C B=12$[/tex]. The subtraction property can be used to find [tex]$CB =6$[/tex]. The symmetric property shows that [tex]$6=A C$[/tex]. Since [tex]$C B$[/tex] [tex]$=6$[/tex] and [tex]$6= AC , AC = CB$[/tex] by the property. So, [tex]$\overline{ AC } \cong \overline{ CB }$[/tex] by the definition of congruent segments. Finally, C is the midpoint of [tex]$\overline{ AB }$[/tex] because it divides [tex]$\overline{ AB }$[/tex] into two congruent segments.
