Answer:
3+4i
Step-by-step explanation:
let x be the answer
(3-4i)x=25
x=25/(3-4i)
multiply by the conjugate
x=(25(3+4i))/25
x=3+4i
Answer:
12.05%
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 12.050249999994%/100 = 0.12050249999994 per year,
then, solving our equation
I = 2000 × 0.12050249999994 × 0.666666666667 = 160.67
I = $ 160.67
The simple interest accumulated
on a principal of $ 2,000.00
at a rate of 12.050249999994% per year
for 0.666666666667 years is $ 160.67.
Only (a) describes a one-to-one function. (b) fails because
