Hello!
1 floz divided by 100 = 0.01
0.01 x 10 = 0.1 floz for 10 drops.
Answer:
A(t) = 300 -260e^(-t/50)
Step-by-step explanation:
The rate of change of A(t) is ...
A'(t) = 6 -6/300·A(t)
Rewriting, we have ...
A'(t) +(1/50)A(t) = 6
This has solution ...
A(t) = p + qe^-(t/50)
We need to find the values of p and q. Using the differential equation, we ahve ...
A'(t) = -q/50e^-(t/50) = 6 - (p +qe^-(t/50))/50
0 = 6 -p/50
p = 300
From the initial condition, ...
A(0) = 300 +q = 40
q = -260
So, the complete solution is ...
A(t) = 300 -260e^(-t/50)
___
The salt in the tank increases in exponentially decaying fashion from 40 grams to 300 grams with a time constant of 50 minutes.
Answer:
r = 18/pi
or approximately 5.7325 inches
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
36 = 2*pi*r
Divide each side by 2 pi
36/(2pi) = r
18/pi = r
Letting pi = 3.14
18/3.14
5.732484076 = r
