BEST ANSWER GETS A METAL!!!!Which pair of complex numbers has a real-number product?

(1 + 3i)(6i)
(1 + 3i)(2 – 3i)
(1 + 3i)(1 – 3i)
(1 + 3i)(3i)

Answers

we will proceed to verify each case to determine the solution

remember that

$i^(2) =-1$

case A) $(1 + 3i)(6i)$

applying distributive property

$(1 + 3i)(6i)=1*6i+3i*6i \n=6i+18i^(2)\n=6i+18*(-1)\n=6i-18$

$-18+6i$ ------> is not a real number

therefore

the case A) is not a real number product

case B) $(1 + 3i)(2-3i)$

applying distributive property

$(1 + 3i)(2-3i)=1*2+1*(-3i)+3i*(2)+3i*(-3i)\n=2-3i+6i-9i^(2)\n=2+3i-9*(-1) \n=11+3i$

$11+3i$ ------> is not a real number

therefore

the case B) is not a real number product

case C) $(1 + 3i)(1-3i)$

applying difference of square

$(1 + 3i)(1-3i)=(1)^(2)-(3i)^(2)\n=1-9i^(2)\n=1-9*(-1) \n=10$

$10$ ------> is a real number

therefore

the case C) is a real number product

case D) $(1 + 3i)(3i)$

applying distributive property

$(1 + 3i)(3i)=1*3i+3i*3i \n=3i+9i^(2)\n=3i+9*(-1) \n=3i-9$

$-9+3i$ ------> is not a real number

therefore

the case D) is not a real number product

the answer is

$(1 + 3i)(1-3i)$

The answer is (1 + 3i)(1 – 3i).

Write a explicit formula for the sequence 10, 9.5, 9, 8.5, 8 then find ^a8

Answers

Answer:

Explicit formula for the sequence is $a_n=10.5-0.5n$ and $a_8=6$

Step-by-step explanation:

Given: Sequence = 10, 9.5 , 9 , 8.5 , 8

To find: Explicit Formula for the sequence and 8th term of sequence

1st term of sequence = 10

2nd term of sequence = 9.5

3rd term of sequence = 9

4th term of sequence = 8.5

5th term of sequence = 8

Difference between 2nd and 1st term = 9.5 - 10 = -0.5

Difference between 3rd and 2nd term = 9 - 9.5 = -0.5

Since, Difference is same in both cases

⇒ It is Arthematic Progression

⇒ First term, a = 10 and Common term, d = -0.5

using formula of AP for nth term we get,

$a_n=a+(n-1)d$

$a_n=10+(n-1)(-0.5)$

$a_n=10-0.5n+0.5$

$a_n=10.5-0.5n$

⇒ 8th Term of AP, $a_8=10.5-0.5*8=10-4=6$

Therefore, Explicit formula for the sequence is $a_n=10.5-0.5n$ and $a_8=6$

Answer:

The term number eight is 6.5

$a_(8)=6.5$

Step-by-step explanation:

The given sequence is an arithmetic sequence, because each term can be found by applying a difference.

In this case, you can observe that such difference is -0.5, because each term is going down by 0.5 units.

The formula that describes an arithmetic sequence is

$a_(n)=a_(1)+(n-1)d$

Where $a_(n)$ is the last term, $a_(1)$ is the first term, $n$ is the position of the last term and $d$ is the difference.

Each variable is

$a_(1) =10\nd=-0.5\nn=8\n$

Where we are gonna find $a_(8)$ the term number eight. So, replacing values, we have

$a_(n)=a_(1)+(n-1)d\na_(8)=10+(8-1)(-0.5)\na_(8)=10+7(-0.5)=10-3.5\na_(8)=6.5$

Therefore, the term number eight is 6.5.

Answers

Answer:

A. y = 5/4x - 3

B. slope is 5/4

C. y intercept is -3

D. Increasing

Step-by-step explanation:

5x - 4y = 12

Slope intercept form: y = mx + b

4y = 5x - 12

y = 5/4x - 3

Slope is 5/4

Y intercept is when x = 0 so it is -3

the slope is positive, therefore the line is increasing
