90 hours. If you divide the total number of gallons (6750) by the rate of 75 gal/hour, it will take 90 hours to fill the whole pool.
Answer:
Step-by-step explanation:
3, -3, -4
Answer:
3
Step-by-step explanation:
1: Turn the mixed fraction into improper.
2: Multiply 3/5 to each side
3: The you get x = 3
You need to multiply the fraction instead of division because multiplying by the reciprocal is the same as dividing the normal fraction.
Answer:
The population size after four days is calculated as 168.
Step-by-step explanation:
Let the population size be P
t be the time variable which is measured in hours
Therefore,
by the differential equation
= 0.8329P
So,by solving and expifying the equation on both sides, we get
P = Ae^0.8329t
Therefore,from the first equation we get
P(0) = 6,
A = 6.
Therefore the population size after four days is
P(4) =![{6}\times{e^0.8329(4)}](https://tex.z-dn.net/?f=%20%7B6%7D%5Ctimes%7Be%5E0.8329%284%29%7D)
= 168( rounded to nearest whole number)
If you have a graphing calculator, you can simply type it into y= and it will graph it for you. But if you need coordinates, the line runs through (0,2) , (4,5) , and (-4,1)
