Solve for equation x. <br> 3In(x)+2In(4)=In(128)

Serggg [28]

$Domain:\ x > 0\\\\3\ln(x)+2\ln(4)=\ln(128)\qquad\text{use}\ \lag_ab^n=n\log_ab\\\\\ln(x^3)+\ln(4^2)=\ln(128)\qquad\text{use}\ \log_ab+\ln_ac=\ln_a(bc)\\\\\ln(16x^3)=\ln(128)\iff16x^3=128\qquad\text{divide both sides by 16}\\\\x^3=8\to x=\sqrt[3]8\\\\\boxed{x=2}\in D$

Please help with geometry

Mariana [72]

Answer: The angle of depression is 51.34°.

Step-by-step explanation:

1. You can make the diagram shown in the figure attached. Where $A$ is the point where the clue is and $B$ is the point where Tyler is.

2. To calculate the angle of depression, which is identified in the diagram as $\alpha$ , you can use $tan^{-1}$ , as following:

$tan^{-1}(\alpha)=\frac{3.5}{2.8}$

3. Then, you obtain the following angle of depression from the clue to the point where Tyler is:

$\alpha=51.34$ °
