Answer:
The monthly payment would be $ 87.76
Step-by-step explanation:
Since, the monthly payment formula of a loan,
Where,
PV = present value of the loan,
r = annual rate of interest,
n = number of months,
Here, PV = 500, r = 18% = 0.18, t = 6 months,
Hence, the monthly payment,
( using calculator )
They are -1, 4 and 7.
x^3 - 10x^2 + 17x + 28 = 0
Observation of this equation shows that there is an x -intercept at x = -1 because
-1^3 - 10^(-1)^2 - 17(1) + 28 = -28 + 28
= 0.
So x + 1 must be a factor so we can do the division:
x + 1 ) x^3 - 10x^2 + 17x + 28 ( x^2 - 11x + 28
x^3 + x^2
-11x^2 + 17x
-11x^2 - 11x
28x^2 + 28
x^2 - 11x + 28 = ( x - 4)(x - 7)
x = 4, 7.
Answer: $15966.08
The formula to calculate the compound amount is given by :-
, where P = initial deposit amount.
Time = Time period .
r= Rate of interest in decimal (compounded once per year)
Given : P= $ 12000
r= 7.4 percent =0.074
t= 4 years
Then, the compound amount after 4 years :
Hence, compound amount after 4 years = $15966.08
x=10
