If f(x) = log↓2 (x + 4), what is f↑−1(3)
never [62]
As you already know, to get the inverse of any expression, we start off by doing a switch on the variables, and then we solve for "y".

\bf \textit{Logarithm Cancellation Rules}
\\\\
log_a a^x = x\qquad \qquad a^{log_a x}=x\\\\
-------------------------------\\\\
\stackrel{f(x)}{\underline{y}}=log_2(x+4)\qquad \qquad \stackrel{inverse}{x=log_2(\underline{y}+4)}
\\\\\\
2^x=2^{log_2(y+4)}\implies 2^x=y+4\implies 2^x-4=\stackrel{f^{-1}(x)}{y}
\\\\\\
2^3-4=f^{-1}(3)\implies 8-4=f^{-1}(3)\implies 4=f^{-1}(3)

you are working on a project for school. the project will take 12 hours to finish in all. so far, you have worked on the project
nasty-shy [4]

Answer:

6 hours and 45 minutes

Step-by-step explanation:

First, convert 12 hours into minutes.

12*60=720

Convert 5 hours to minutes and add 15

5*60=300+15=315

Subtract 720 from 315.

720-315=405

Convert into hours and minutes.

405/60=6.75

0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
