What is a complex series notation that equals one

Mathematics
2 answers:
seropon [69]3 years ago

2 + i^2 = 1. also i^4 = 1

3 + i^2 = 2 also 2i^4 = 2

4 + i^2 = 3 also 3i^4 = 3

the complex series has a form Z = a + ib, where a is the real number and ib is the imaginary part.

we know i = √-1 so i^2 = -1 and (i^2)^2 = (-1)^2 = 1. or i^4 = 1.

also,

2 + i^2 = 1. since i^2 = -1, 2 + -1 = 2-1 = 1.

if we want to find 2,

3 + i^2 = 2. since we know i^2 will be -1, set the a value to be 1 more the value you need. for example if you want 3, set a to be 4.

for 3.

first make a to be 1 more than 3 which is 4.

3 = 4 + i^2.

we know the complex number has standard form a+ib

Inorder to find our answer ib^2 should.be 1

Ex:-

2-i

2:-

\\ \sf\longmapsto 2+2i^2

  • i^4=1

(Solving Equations) Ken has $20.00. Coffee costs $4.79 per pound. Which equation will calculate the number of pounds of coffee,
aev [14]

Answer: A. 4.79(n)=20.00

Step-by-step explanation:

we need to find what amount of coffee (per pound) is equivalent to $20.00

so we take the unknown amount (n) and multiply it by $4.79

for example, say Ken wants 4 pounds, we need to know if it is equivalent to $20.00

so take 4.79 and multiply it by 4 to see if it is equal to or less than $20.00 in this case $4.79 x 4 = $19.16  

hope this helps (^_^)

Answer:

Part 9) The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13

Part 10) The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot

Step-by-step explanation:

Part 9)

Let

x ----> number of items on Emily's grocery list

x ----> number of items on Bobby's grocery list

we know that

y=2x+3 ----> equation A

x=y-8 ----> equation B

Solve by substitution

Substitute equation A in equation B

x=(2x+3)-8

solve for x

x=2x-5

2x-x=5

x=5

Find the value of y

y=2(5)+3=13

therefore

The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13

Part 10)

Let

x ----> the height of the taller bookshelf in feet

y ----> the height of the shorter bookshelf in feet

we have

x=5y-1 ----> equation A

Remember that

1\ ft=12\ in

To convert inches to feet divide by 12

so

60\ in=60/12=5\ ft

x+y=5 ----> equation B

Solve the system by substitution

substitute equation A in equation B

(5y-1)+y=5

solve for y

5y+y=5+1

6y=6

y=1\ ft

Find the value of x

x=5(1)-1=4\ ft

therefore

The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot

Slav-nsk [51]
So take 13, 8 and 4 and add those together to get the budget she needs for the month.
13+8+4=25
so she needs $25 in all, to find how much more than 16 she needs you take 25 and minus 16 from it.
25-16=19
so she needs $19 more to have a balanced budget.
