A banker earns a $75,000 annual salary, a 2,35% commission on any approved loans for the bank’s business customers, and a fee of

satela [25.4K]

Answer:

Amount earned = $151,113

Step-by-step explanation:

Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;

We proceed as follows; we have the following;

1. Annual salary of $75,000

2. 2.35% on approved loans.

Approved loans = 2.8 million

Commission = 2.35/100 * 2.8 million = $65,800

3. $3.75 for each processed loan application

Total = 2750

Amount = 3.75 * 2750 = $10,312.50

Total amount earned is thus;

$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar

What is the value of i^20+1?

ICE Princess25 [194]

You know

$i^2=-1$

Squaring both sides gives

$(i^2)^2=(-1)^2\implies i^4=1$

Then raising both sides to any integer power $n$ gives

$(i^4)^n=1^n\implies i^{4n}=1$

That is, any power of $i$ where the power is a multiple of 4 will always be equal to 1.

$i^{20}+1=1+1=2$

But perhaps you mean to write 20+1 as the exponent, in which case

$i^{20+1}=i^{20}i=i$
