Find and sketch the domain for the function. f(x, y)equalsln left parenthesis x squared plus y squared minus 16 right parenthesis select the correct choice below and, if necessary, fill in the answer box to complete your choice.

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
