Point III is about <em>real interest rate</em>
point I doesn't apply since both nominal and effective ir are calculated by year
let alone the fact that if you look close to those numbers it would probably mean that the loan had 1year and 1 day duration :)
the II answer is the correct one
if the loan is compounded at 6 months you have to add the interest of the first 6 months interest to the total interest to find out the effective interest rate
The answer is 20 because 292+20=312
Here is your answer:
Its scientific notations:
Its negative so your going to the left:
2.8×10^-4
=0.000028
The square meters of the area the oil slick will cover is 9.6 × 10⁶ m².
<h3>What is meant by volume?</h3>
Volume is defined as the amount of three-dimensional space enclosed by a closed surface.
- The liter (L) is the metric system's base volume unit, with several extended volume units also available.
- There are also many metric volume units based on the a cubic length dimension, including such cubic meters or cubic centimeters. Gallons and ounces are examples of imperial volume units.
Now, as per the given question;
First, we determine the entire volume of oil in gallons by multiplying the volume per barrel even by total number of barrels:
15×42 gal = 630 gal
This volume must be converted to square meters:
V = 630 gal × (0.00379 m³/ gal
V = 2.4 m³
The thickness (height) of a oil film in meters is required:
h = 250 nm × (m/10⁻⁹nm)
h = 2.5 × 10⁻⁷m
The surface area of a oil film is calculated by dividing the oil volume by height of the oil film.
A = V/h
A = 2.4 m³/2.5 × 10⁻⁷m
A = 9.6 × 10⁶ m²
Therefore, the area of the oil slick cover is found to be 9.6 × 10⁶ m².

The rule for multiplying similar bases with exponents is:
(a^b)*(a^c)=a^(b+c)
In this case you have:
(x^9)(x^2)
x^(9+2)
x^11
