NEED HELP ASAP. BEST ANSWER GETS BRAINLIEST. f is inversely proportional to d.
When d=50, f=256
Write the formula for f in terms of d

d = 12800/f

Step-by-step explanation:

variation of proportion is 256(50) = 12,800

d = 12800/f

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  

x
