Answer:

interest = $600

Step-by-step explanation:

for simple interest,

I = PTR/100

Principal (P) = $5000

Time (T) = 3 YEARS

Rate(R) = 4%

therefore, Interest (I) = $5000 × 3 × 4 / 100

= $ 600

An oil tanker breaks apart and starts leaking. As time goes on, the rate at which the oil is leaking out will diminish. Suppose

Alborosie

Answer:

62.77 million gallons

Step-by-step explanation:

Given,

The function that shows rate of leaking oil per minute in after t hours,

$R(t) = \frac{0.7}{1+t^2}$

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,

Hence, the quantity of oil leaked out in the first 3 hours,

$V(t) = \int_{0}^{180} R(t) dt$

$=\int_{0}^{180} \frac{0.7}{1+t^2} dt$

$=0.7 \int_{0}^{180} \frac{dt}{1+t^2}$

$=0.7[tan^{-1}(t)]_{0}^{180}$

$=0.7(tan^{-1}(180) - tan^{-1} (0))$

$=0.7(89.68)$

= 62.77 million gallons
