Answer:
(a) V(0) = 50 gal, V(20) = 0 gal
(b)At t= 0 the tank is full.
At t=0 the tank is empty
(c)
Time volume
0 50 gal
5 37.5 gal
10 25 gal
15 12.5 gal
20 0 gal
(d)
Net change of volume = 50 gal
Step-by-step explanation:
Given that the capacity of the tank is 50 gal.
Torricelli's Law gives the volume of water remaining in the tank after t minutes as
(a)
To find V(0), we put t = 0 in the above equation
= 50 gal
To find V(20), we put t =2 0 in the above equation
= 0 gal
(b)
At t= 0 the tank is full.
At t=0 the tank is empty.
(c)
Time V(t)
0
5
10
15
20
(d)
Net change of volume = V(0) -V(20)
=(50-0) gal
= 50 gal
To solve this, we will first use order of operations to multiply the terms inside the parentheses, multiply the product by the term outside of the parentheses, and then add from left to right.
5.6 * 2 = 11.2
11.2 * 4.5 = 50.4
50.4 + 1.2 = 51.6
Therefore, 51.6 is the solution.
Point slope formula:
We know that:
y1=-1
x1=2
m=-5
So we plug those into the formula
negative + negative= positive so..
