A tank contains 8000 L of pure water. Brine that contains 35 g of salt per liter of water is pumped into the tank at a rate of 25 L/min. The concentration of salt after t minutes (in grams per liter) is C(t) = 35t 320 + t . As t → [infinity], what does the concentration approach?

The concentration of salt in the tank approaches

Step-by-step explanation:

Data provide in the question:

Water contained in the tank = 8000 L

Salt per litre contained in Brine = 35 g/L

Rate of pumping water into the tank = 25 L/min

Concentration of salt

Now,

Dividing both numerator and denominator by , we have

Here,

The concentration of salt in the tank approaches

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
