Answer:
1+i
Step-by-step explanation:
To find the 8th roots of unity, you have to find the trigonometric form of unity.
1. Since then
and
This gives you
Thus,
2. The 8th roots can be calculated using following formula:
Now
at k=0,
at k=1,
at k=2,
at k=3,
at k=4,
at k=5,
at k=6,
at k=7,
The 8th roots are
Option C is icncorrect.
Okay so I'm going to set up a equation:
5.27= 3.40+ 0.85x, we have our total our price of one pineapple and our variable
next I isolate the variable:
5.27-3.40=0.85x
next:
1.87=0.85x
x= 2.2
she bought 2.2 pounds of tomatoes
This answer is c (x-4)(x+4)
We know that there are 26 letters in the alphabet, and 10 different digit possibilities (0-9). We also know that the plates each have 3 letters and 2 digits. and they can be repeated. To solve this, we multiply 26 X 26 X 26 X 10 X 10 to get the total amount of possibilities 1,757,600. Hope this helps.
The formula for a cube is l x w x h. But, these are all the same. So, you multiply 4 by 4 three times. The volume of the cube is 64^2 inches.
