Answer:
The percentage increase in salary of employee is 7.14 %
Step-by-step explanation:
Given as :
The initial pay of employee = $35,000 per year
The increase pay of employee = $37,500 per year
Let The percentage increase in salary = X %
So, X = × 100
Or, X = × 100
Or, X = × 100
∴ X = 0.0714 × 100 = 7.14 %
Hence The percentage increase in salary of employee is 7.14 % Answer

Answer:
A)
At t = 0, oil is leaking out of a ruptured tanker at the rate of 30 thousand liters per minute.
At t = 60, oil is leaking out of a ruptured tanker at the rate of 0.1355 thousand liters per minute.
B)
331.82 thousands of liters leak out during the first hour.
Step-by-step explanation:
The oil leakage rate, in thousand liters per minute, is:
A. At what rate, in thousands of liters per minute, is the oil leaking out
At t = 0:
This is r(0)
At t = 0, oil is leaking out of a ruptured tanker at the rate of 30 thousand liters per minute.
At t = 60:
This is r(60)
At t = 60, oil is leaking out of a ruptured tanker at the rate of 0.1355 thousand liters per minute.
B. How many thousands of liters leak out during the first hour?
r(t) is in thousand liters per minute.
Each hour has 60 minutes.
So the answer to this question is the integral from 0 to 60 of r(t).
Integral of the exponential function
So
, from t = 0 to t = 60.
This is
331.82 thousands of liters leak out during the first hour.
