Step-by-step explanation:
the pythagorean theory a^2 + b^2 = c^2
16^2 + 12^2 =
144 + 256 = 400
sqr root of 400 is 20

Table
Hours 2 4 6 8
Water remining 43 36 29 22
If you calculate the change in water remaining / hours elacpse you ge a constant value:
[36-49]/[4-2] = [29-36]/[6-4-29] = [22-29] / [8-6] = -7/2 = - 3.5
That is the slope.
The y-intercept is y when x =0, this is the volume of water when time is 0.
You can calculate it by adding 7 to 43 = 43 + 7 = 50
Then, the equation is y = -3.5x + 50
