Answer:
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
Step-by-step explanation:
Given the data in the question;
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?
dA/dt = rate in - rate out
first we determine the rate in and rate out;
rate in = 3pound/gallon × 5gallons/min = 15 pound/min
rate out = A pounds/1000gallons × 5gallons/min = 5Ag/1000pounds/min
= 0.005A pounds/min
so we substitute
dA/dt = rate in - rate out
dA/dt = 15 - 0.005A
Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
Answer:
cos 30 + sin60 + sin30 - cos60
we know that sin ( 90 -a ) = cos a { and vice versa }
therefore by using this property,
sin ( 90 - 30 ) + sin 60 + sin 30 - sin ( 90-60)
sin 60 + sin 60 + sin 30 - sin 30 =
<u>2 sin 6</u><u>0</u>
That's the answer I got. Tell me if it's correct
Answer:
The orange goldfish is 25 inches long
Step-by-step explanation:
Sorry I hope my answer makes sense, his question was a lil hard to read
2 x 11 = 22 + 3= 25
Answer: The answer is 25
Step-by-step explanation:
First, You would add the two numbers together, which you get 155
Then, the degrees of a triangle is equal to 180. So you would subtract 155 from 189, and you should get 55.
Hope this helps :3
