Can someone explain to me what b means? im confused
vovangra [49]

Answer:

This is a personal reflection of your own thoughts and feelings

example its accurate yes because you have good things to do and say about yourself and to help yourself.

example its not accurate because there are circumstances that may get in the way or bring you down too often. But to compensate that you can try to listen more.

Another example

example it is accurate because i have thought of 4 major things about why health is this level and have accounted for the mind and body elements as well as my own awareness to comparison and reflection in what i strive or to what is should strive to be.

example it is not accurate because in such comparison of mind and body and comparison i sometimes still find i could be so much more happier or healthier or more self aware etc or listen more to myself or others etc.. .

Another example

example it is accurate because i have interest in this part of my health and am self aware to my own interests and find time for them at all costs.

.

example it is not accurate as im still learning how to be self aware, and can only think of what is good health right now in certain circumstances.

An example of certain circumstances may be when you are around your best friends and not in all new friend circumstances as you need more interests to give confidence maybe and if this is not why then try to pin point what holds you back in personal development.

6. A tank contains 100-gallon of pure water. At time t = 0, a solution containing 2 lb of salt per gallon flows into the tank at
SOVA2 [1]

Answer:

The answer is below

Step-by-step explanation:

Let Q represent the amount of salt in the tank at time t.

\frac{dQ}{dt}= flow\ in - flow\ out\\ \\flow\ in=3\ gal/min*2\ lb/gal=6\ lb/min\\\\net\ gain\ in\ tank\ volume=3-4=-1, henceflow\ out= \frac{4Q}{100-t} \\\\\frac{dQ}{dt}= 6-\frac{4Q}{100-t} \\\\\frac{dQ}{dt}+ \frac{4Q}{100-t}=6\\\\The \ integrating\ factor\ is:\\\\IF=e^{\int\limits {\frac{4}{100-t} } \, dt }=e^{-4\int\limits {\frac{-1}{100-t}}=e^{-4ln(100-t)}=(100-t)^{-4}}\\\\Multiplying\ through  \ by\ IF: \\\\(100-t)^{-4}\frac{dQ}{dt}+ (100-t)^{-4}\frac{4Q}{100-t}=6(100-t)^{-4}\\\\

Integrating:\\\\A(100-t)^{-4}=-2(100-t)^{-3}+c\\\\A=-2(100-t)+\frac{c}{(100-t)^{-4}} \\\\at, t=0,A=0\\\\0=-2(100-0)+\frac{c}{(100-0)^{-4}}\\\\c=0.02\\\\A=-2(100-t)+\frac{0.02}{(100-t)^{-4}}
