Tan B=1.33. If you put tan^-1 and find the angle of A, you’ll get 36.87, so 90-36.87=53.13, then put Tan53.13, you’ll get TanB=1.33

The area of a circle is 25pi m squared what is the circumference

IceJOKER [234]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
A=25\pi 
\end{cases}\implies 25\pi =\pi r^2\implies \cfrac{25\pi }{\pi }=r^2
\\\\\\
25=r^2\implies \sqrt{25}=r\implies 5=\boxed{r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad C=2\pi\left( \boxed{5} \right)\implies C=10\pi$

Answer:

D. 4

Step-by-step explanation:

Without actually solving the equation, recall that for $a=|b|$ , there are two cases:

$\begin{cases}a=b, \\a=-b\end{cases}$

In the given equation $|x-2|^{10x^2-1}=|x-2|^{3x}$ , there are two pairs of absolute value symbols.

Since each has two cases, there must be a total of $2\cdot 2=\boxed{4}$ different equations created.

All four cases are:

$\begin{cases}(x-2)^{10x^2-1}=(x-2)^{3x},\\(-x+2)^{10x^2-1}=(x-2)^{3x},\\(x-2)^{10x^2-1}=(-x+2)^{3x},\\(-x+2)^{10x^2-1}=(-x+2)^{3x}\end{cases}$

Exponents differ, hence clearly there are four possible solutions to this equation.

You can solve for all four values of $x$ by taking the log of both sides and using a bit of algebra to verify you have four solutions.
