Answer:
1/5
Step-by-step explanation:
(0, -2) & (-5, -3)
slope formula: (y₂ - y₁) / (x₂ - x₁)
(-3 + 2) / (-5 - 0) =
(-1) / (-5) =
1/5
Answer:
y = (2 - 7) / (6 - (-9)) * (x - (-9)) + 7
y = -5 / (6 + 9) * (x + 9) + 7
y = -5 / 15 * (x + 9) + 7
y = -1/3 * (x + 9) + 7
y = -1/3 * x - 3 + 7
y = -1/3 * x + 4
Answer:
96.46
Step-by-step explanation:
Volume of the Gallon =140 gallons
At time t=0, V(0)=40 gallons
V(t)=2t+k, Where K is a constant.
Since V(0)=40
V(0)=2(0)+k=40
k=40
V(t)=40+2t
The Change in Salt Concentration
Rearranging
Using Integrating Factor:
At t=0, C(0)=0.125, k_0=5
At V(t)=140
V(t)=40+2t=140
t=50
Just the tank overflows, C(t)=96.46
