Answer:
The answer is A :)) hehe.
Answer:
7.5
Step-by-step explanation:
the slope m is a measure of the rate of change
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (6, 45 ) and (x₂, y₂ ) = (9, 67.5 )
m = 
= 
= 7.5 ← rate of change
Answer:
12.29minutes
Step-by-step explanation:
The net flow rate = flow in - flow out = F(t) - E(t) = t+6/1+t - ln(t+2)/t+1 = [(t + 6) - ln(t+2)]/(t+1)
So, the amount of water present in the tank at time, t is A = net flow rate × time = [(t + 6) - ln(t+2)]/(t+1) × t = t[(t + 6) - ln(t+2)]/(t+1)
At t = 10 minutes,
A = t[(t + 6) - ln(t+2)]/(t+1)
A = 10[(10 + 6) - ln(10+2)]/(10+1)
A = 10[16 - ln12]/11
A = 10[16 - 2.485]/11
A = 10[13.515]/11
A = 135.15/11
A = 12.29 minutes
