What you’re doing is breaking it down into its parts and writing it into an equation that way long hand.
3 + .4 + .00 + .005
Answer:
a)
b)
Step-by-step explanation:
It can be seen in the graph that the water velocity and solution velocity is the same, but the salt concentation will be lower
Water velocity
Solution velocity
Brine concentration =
a) Amount of salt as a funtion of time Sa(t)
b)
This value was to be expected since as the time passes the concentration will be lower due to the entrance to the pure water tank
Answer:
Step-by-step explanation:
Slope intercept form: when is the slope of the line and is the y-intercept (the y-coordinate of the point the line crosses the y-axis)
<u>1) Find the slope (</u><u>)</u>
when the points are and
We can use any two points that the table gives us to plug into this equation. For example, we can use the points (14,0) and (0,7):
Simplify the fraction
So far, our equation looks like this:
<u>2) Find the y-intercept (</u><u>)</u>
The y-intercept is the y-coordinate of the point the line crosses the y-axis, or in other words, it's the value of y when x is equal to 0.
Looking at the table, we can see that y is equal to 7 when x is equal to 0, so, therefore, .
Now, this is our final equation after plugging in and :
I hope this helps!
Answer:
y = -3
Step-by-step explanation:
The midline value is the added constant, -3. The equation for the line is ...
y = -3
Each time it is being subtracted by 6.5
