x^2 - 2x + 2
x = 1 + i
(1 + i)^2 - 2(1 + i) + 2
<em><u>Distributive property.</u></em>
(1 + i)(1 + i) - 2 - 2i + 2
<em><u>Continue distributive property on left side.</u></em>
1 + i + i + i^2 - 2 - 2i + 2
<em><u>Combine like terms.</u></em>
1 + 2i + i^2 - 2 - 2i + 2
1 + i^2
<em><u>i^2 can be interpreted as -1.</u></em>
1 - 1 = 0
The expression is equal to 0.
They marked it up to 2979 since 993*3(aka 200%). You then multiply 2979 by 1.14 to get the total of $3396.06
Answer:
<u>radius: 8.4</u> <u>Area: 221.5</u>
Step-by-step explanation:
16.8 <em>divided </em>by 2 = 8.4
The Formula for finding the area of circle= R₂ (radius squared: radius times itself) Multiplied by pi. pi = 3.14
8.4₂ multiplied by 3.14
Answer:
average hours worked = 8 hours / day
Explanation:
To get the average, we divide the total number of hours worked by the total number of days.
i.e.
average hours worked = total number of hours / total number of days
From the givens we have:
Total number of hours = 8 + 10 + 7 + 9 + 6 = 40 hours
Total number of days = 5 days
Substitute in the above rule to get the average as follows:
average hours worked = 40 / 5 = 8 hours / day
Hope this helps :)
