Answer:
Jean paid $2,286 for the snow thrower, with a finance charge of $306.
Step-by-step explanation:
Given that Jean bought a $ 1,980 snow thrower through an initial payment of 10% of the initial value, and 18 monthly payments of $ 116, to determine the final price paid by Jean, the following calculation is required:
(1,980 x 0.1) + (18 x 116) = X
198 + 2,088 = X
2,286 = X
Therefore, the final price paid for Jean was $ 2,286.
In turn, the finance charge arises from the difference between the final price and the list price, that is:
2,286 - 1,980 = X
306 = X
Thus, the finance charge is $ 306.
Answer:

Step-by-step explanation:
<u><em>Given Equation is </em></u>
=> 
Comparing it with
, we get
=> a = 2, b = 7 and c = -9
So,
Sum of roots = α+β = 
α+β = -7/2
Product of roots = αβ = c/a
αβ = -9/2
<em>Now, Finding the equation whose roots are:</em>
α/β ,β/α
Sum of Roots = 
Sum of Roots = 
Sum of Roots = 
Sum of roots = 
Sum of roots = 
Sum of Roots = 
Sum of roots = 
Sum of roots = S = 
Product of Roots = 
Product of Roots = P = 1
<u><em>The Quadratic Equation is:</em></u>
=> 
=> 
=> 
=> 
This is the required quadratic equation.
The answer for your question question is 3+ 16/3 i
Scale = 1cm:3km
Therefore area of lake = 81Km
1:3 = x:81
= 27:81
Therefore the area on map is 27cm
