Answer:
Step-by-step explanation:
Volume of water in the tank = 1000 L
Let y(t) denote the amount of salt in the tank at any time t.
Initially, the tank contains 60 kg of salt, therefore:
y(0)=60 kg
<u />
<u>Rate In</u>
A solution of concentration 0.03 kg of salt per liter enters a tank at the rate 9 L/min.
=(concentration of salt in inflow)(input rate of solution)
<u>Rate Out</u>
The solution is mixed and drains from the tank at the same rate.
Concentration,
=(concentration of salt in outflow)(output rate of solution)
Therefore, the differential equation for the amount of Salt in the Tank at any time t:

What type of number is Select all that apply
Let's start by taking a look at all the four sets of numbers.
<h2>A: Whole number</h2><h3>{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22...∞}</h3>The set is shown above. To be honest, this is an infinitely small part of the number set; the whole number set would take FOREVER to type ;)
<h2>B: Integers</h2><h3>{∞...-2,-1,0,1,2,3,4,5,6,7,8,9...∞}</h3>Wow, this set starts at negative infinity and ends at positive infinity!
<h2>C: Rational</h2>This set consists of all integers, decimals, and fractions.
<h2>D: Irrational</h2>That's where the desired number belongs!

-8, -19, -30, -49 , -60
<u>Step-by-step explanation:</u>
Here we have the following sequence :
-8, -19, -30, _ , _
- First term of sequence is -8 .
- Second term of sequence is -19 :
- Third term of sequence is -30 :
- Fourth term of sequence is :
- Fifth term of sequence is :
Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. and common difference
having general equation as :
