The answers to the questions
To divide fractions you multiply the reciprocal
480 ÷ 1/3 =
480 × 3/1 = 1,440
This can be solved by equating the future value of the payment F1, and the future value of the annuity F2, after n=12*15=180 months.
i is the monthly interest.
P=payment of 90000
A=monthly amount of 850
F1=P(1+i)^n=90000(1+i)^180
F2=A*((1+i)^n-1)/i=850((1+i)^180-1)/i
equate F1=F2 and solve for i (only unknown) by trial and error, fix-point iteration or Newton's method to get i=0.00650439,or 0.650439%
The monthly interest rate is 0.650439%.
Therefore the APR=12*i=7.805271%, or the effective interest rate is
(1+i)^12-1=8.09064%
Answer:
The expression equivalent to (4x^3 y^5)(3x^5 y)^2 is 36x^13y^7...
Step-by-step explanation:
The expression is:
(4x^3 y^5)(3x^5 y)^2
First look at the second expression:
(3x^5 y)^2 = (3)^2 (x^5)^2 (y)^2
(3x^5 y)^2 = 9x^10y^2
Now we will multiply the expression:
(4x^3 y^5) (9x^10y^2)
(4*9)(x^3 * x^10) (y^5 * y^2)
We know that the exponents with same base will be added together.
36x^3+10 y^5+2
36x^13y^7
Thus the expression equivalent to (4x^3 y^5)(3x^5 y)^2 is 36x^13y^7....
