y = 12^x


x = 12^y

12^y = x

\log 12^y = \log x

y \log 12 = \log x

y = \dfrac{\log x}{\log 12}

y=12^x\ \ \ |log_{12}\\\\\log_{12}y=\log_{12}12^x\\\\\log_{12}y=x\log_{12}12\\\\x=\log_{12}y


y=12^x\to y^{-1}=\log_{12}x;\ x\in\mathbb{R^+}\to\ y^{-1}=\dfrac{\log x}{\log12};\ x\in\mathbb{R^+}\to y^{-1}=\dfrac{\ln x}{\ln 12}

Used:\\\\\log_aa=1\\\\\log_ab^n=n\log_ab\\\\\log_ab=\dfrac{\log_cb}{\log_ca}

A straight line has a slope of 2.08. Calculate the angle that the line makes with the x (horizontal) axis.
zubka84 [21]

Answer:

The angle that the line makes with x-axis of of 64.3º.

Step-by-step explanation:

Equation of a line, and angle with the x axis:

The equation of a line has the following format:

y = mx + b

In which m is the slope.

The angle that the line makes with the x axis is given by the angle which has tangent m, that is, a = \tan^{-1}{m}.

In this question:

We have that m = 2.08. So

a = \tan^{-1}{2.08} = 64.3

The angle that the line makes with x-axis of of 64.3º.
