Answer:

<h2>-24 + 22i</h2>

Step-by-step explanation:

Use the FOIL method of multiplication of binomials:

(-4+2i)(7-2i) = -28 + 14i + 8i - (-4)i²

Note that i² = -1.  Thus, - (-4)i² = +4, and we then have:

-28 + 22i + 4, or

-24 + 22i

An elevator descends into mine shaft at the rate of 6m/min. If the descend starts from 10m above the ground level , how long wil
AnnyKZ [126]

Answer: Hi!

So first, I'm going to convert "350 below ground level" to -350, as this is what "below ground level" represents.

Now, we should find the total distance traveled. Take the absolute value of -350 (350) and add it to 10, the metres above ground level. This is 360.

We already know the rate of travel; 6m/min. All we have to do now is divide the total distance (360) by the rate of travel (6)!

360 ÷ 6 = 60

So, it took 60 minutes, or one hour, for the elevator to travel down the shaft!

Hope this helps!

Liono4ka [1.6K]

Answer:

Commision may be defined as a percentage cut which an employee, broker, vendor, retailer or other persons within a sale chain receive from an employer or production firm for selling a good or offering a successful service based on agreed terms by both parties. ;

$18700

Step-by-step explanation:

Given :

Commision pattern :

5% on first $200,000

6% on remaining amount

Amount of commission on $345000

0.05 * 200000 = 10,000

0.06 * (345000 - 200000) = 8700

Total commission :

10,000 + 8700 = 18,700
