Hello!
The number line progresses from negative infinity (extreme left) to positive infinity (extreme right). Beginning at zero, the numbers increase in value as they move to the right and decrease in value as they move to the left.
With this knowledge, we can look at the number 17.2 (a positive number) and conclude that it is placed 17.2 units to the right of zero on the number line.
The opposite of 17.2 would be (-17.2). Again, looking at this number (a negative number), we can conclude that it is placed 17.2 units to the left of zero on the number line.
I hope this helps!
14.50 - 6.95 = 7.55$
7.55 + 5.00 = 12.55$ spent on a snack?! dang she was hungry
Salt flows in at a rate of
(2 g/L) * (4 L/min) = 8 g/min
and out at a rate of
(<em>B</em>/(200 + <em>t</em>) g/L) * (3 L/min) = 3<em>B</em>/(200 + <em>t</em>) g/min
where <em>B</em> is the amount of salt in the tank at time <em>t</em>.
Then the net rate at which <em>B</em> changes is governed by the ODE,
Multipy both sides by :
Integrate both sides:
The tank starts with 30 g of salt, so <em>B</em>(0) = 30, which gives
