Let p (x) = x^1 - x^-1 +x^0
p (2) = 2 -1/2 +1
=( 4 -1+2)/2
= 5/2
The interest based on the information given is $2564.
<h3>How to calculate the interest?</h3>
From the information given, the following can be deduced:
Principal = $36900
Time = 178 days
Rate = 14.25%
The simple interest will be:
= (PRT)/100
= (36900 × 14.25 × 178/365)/100
= $2564

Answer:
River D - 2580 miles
River C - 2980 miles
Step-by-step explanation:
Let the length of River D be represented with x
length of river C = 400 + x
total length of both rivers = 5560
x + 400 + x = 5560
2x + 400 = 5560
collect like terms
2x = 5560 - 400
2x = 5160
divide both sides of the equation by 2
x = 5160 / 2
x = 2580
length of river c = 400 + 2580 = 2980
