Answer:
10.75 , 10 (6/24),13/20,-10(6/25)
Answer:
- A(0) = 2; A'(t) = 6 - 0.08A(t)
- A(∞) = 75
Step-by-step explanation:
The initial value is said to be 2 pounds, so A(0) = 2.
__
The influx is (1.5 #/gal)×(4 gal/min) = 6.0 #/min.
The outflow is (4 gal)/(50 gal) × A(t) = 0.08A(t).
The rate of change of A(t) is then ...
A'(t) = 6 - 0.08A(t)
__
When the system reaches steady state, A'(t) = 0, so ...
0 = 6 - 0.08A(∞)
A(∞) = 6/0.08 = 75
75 pounds of salt will be in the tank after a long period.
Answer:
First we have to calculate z
z + 69° = 180°
z = 180° - 69° = 111°
Now that we have 2 out of 3 angle already, we can easily calculate x which is the measurement of the third angle we are looking for:
23° + 111° + x = 180°
x = 180° - 23° - 111°
x = 46°
