Answer:
Step-by-step explanation:
Since 2 of the 3 binomials are identical I would start the distribution there.
(1 + 4i)(1 + 4i) =
I'm sure you have learned in class by now that i-squared is = to -1, so we can make that substitution:
1 + 8i + 16(-1) which simpifies to
1 + 8i - 16 which simplifies further to
-15 + 8i. Now we need to FOIL in the last binomial:
(-15 + 8i)(-4 + 4i) =
Combine like terms to get
Again make the substitution of i-squared = -1:
60 - 92i + 32(-1) which simplifies to
60 - 92i - 32 which simpifies, finally, to a solution of:
28 - 92i
Answer:
The discount points will cost 3749.
Step-by-step explanation:
The first monthly interest payment is $820.
So, annual interest paid = = $9,840
Now, converting the annual interest to decimal = = $93,714.28
As given, the bank requires 4 discount points, this becomes 0.04.
So, total loan amount = = $3748.57 ≈ $3749
Hence, the discount points will cost 3749.
