What is the point of a pythagorean theorem?
1 answer:
The Pythagorean Theorem describes an important geometric relationship between the three sides of a right triangle.
First of all, to understand the Pythagorean Theorem, you need to know about angles and triangles, and you also need to know about exponents and square roots. These things will help you understand how it works and how to solve for a missing side.
The Pythagorean Theorem
For a right triangle
with legs a and b and the hypotenuse c
+
=
The Pythagorean Theorem does not apply to all triangles.

Answer:
Therefore the concentration of salt in the incoming brine is 1.73 g/L.
Step-by-step explanation:
Here the amount of incoming and outgoing of water are equal. Then the amount of water in the tank remain same = 10 liters.
Let the concentration of salt be a gram/L
Let the amount salt in the tank at any time t be Q(t).
Incoming rate = (a g/L)×(1 L/min)
=a g/min
The concentration of salt in the tank at any time t is = g/L
Outgoing rate =
Integrating both sides
[ where c arbitrary constant]
Initial condition when t= 20 , Q(t)= 15 gram
Therefore ,
.......(1)
In the starting time t=0 and Q(t)=0
Putting t=0 and Q(t)=0 in equation (1) we get
Therefore the concentration of salt in the incoming brine is 1.73 g/L
