Basically, the problem is asking us to take 2.20, the length of AB, and work with it through the problem. Well, we are first told that the original polygon is reflected across the x-axis to form the polygon A'B'C'D'E'. This does nothing to the length of AB, so we can move onto the next given section. We are given that A'B'C'D'E' is dilated by a factor of 0.5 (1/2) to form the polygon LMNOP. Here, we will have to take 2.20, the original length, and divide it by 0.5, to get the length of LM. When we perform the operation, we get 1.10, or 1.1. Therefore, the length of LM is 1.10 units. Hope this helped and have a great day!

<h2> Question # 3</h2>

Answer:

$x = 13.094$

Step-by-Step Explanation

Considering the exponential equation

$e^{x-9}-6=54$

Solving the exponentiation equation

$e^{x-9}-6=54$

$\mathrm{Add\:}6\mathrm{\:to\:both\:sides}$

$e^{x-9}-6+6=54+6$

$e^{x-9}=60$

$\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)$

$\ln \left(e^{x-9}\right)=\ln \left(60\right)$

$\mathrm{Apply\:log\:rule}:\quad \log _a\left(x^b\right)=b\cdot \log _a\left(x\right)$

$\ln \left(e^{x-9}\right)=\left(x-9\right)\ln \left(e\right)$

$\left(x-9\right)\ln \left(e\right)=\ln \left(60\right)$

$\mathrm{Apply\:log\:rule}:\quad \log _a\left(a\right)=1$

$\ln \left(e\right)=1$

$x-9=\ln \left(60\right)$

$x=\ln \left(60\right)+9$

$x=13.094$ ∵ $\ln \left(60\right)=4.094$

Therefore, x = 13.094

<h2> Question # 4</h2>

Answer:

$x=0.386$

Step-by-Step Explanation

Considering the exponential equation

$3e^{9x}-6=91$

Solving the exponentiation equation

$3e^{9x}-6=91$

$\mathrm{Add\:}6\mathrm{\:to\:both\:sides}$

$3e^{9x}=97$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3e^{9x}}{3}=\frac{97}{3}$

$e^{9x}=\frac{97}{3}$

$\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)$

$\ln \left(e^{9x}\right)=9x\ln \left(e\right)$

$9x\ln \left(e\right)=\ln \left(\frac{97}{3}\right)$

$\mathrm{Apply\:log\:rule}:\quad \log _a\left(a\right)=1$

$\ln \left(e\right)=1$

$9x=\ln \left(\frac{97}{3}\right)$

$\mathrm{Divide\:both\:sides\:by\:}9$

$\frac{9x}{9}=\frac{\ln \left(\frac{97}{3}\right)}{9}$

$x=\frac{\ln \left(\frac{97}{3}\right)}{9}$

$x=\frac{3.476}{9}$ ∵ $ln\left(\frac{97}{3}\right)=3.476$

$x=0.386$

Therefore, x = 0.386
