Compare the monthly payment amount of annabelle's dream car at two different car dealerships.
dealership a: the car costs $30,000, and the loan has an annual interest rate of 4.8%.
dealership b: the car costs $29,800, and the loan has an annual interest rate of 5.4%.
determine the monthly payment for each dealership, and decide which is cheaper. both interest rates are compounded
monthly. both loans are for 5 years, or 60 months. assume that there is no down payment.

By comparing both the payments we can say that Dealer A is cheaper by $4.50.

Step-by-step explanation:

Dealership A: The car costs $30,000, and the loan has an annual interest rate of 4.8% for 5 years.

The EMI formula is :

Now, p = 30000

r =

n =

Putting values in formula we get;

=>

EMI is = $563.34

Dealership B: The car costs $29,800, and the loan has an annual interest rate of 5.4% for 5 years.

p = 29800

r =

n =

Putting values in formula we get;

=>

EMI = $567.84

By comparing both the payments we can say that Dealer A is cheaper by $4.50.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
