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).

Larry has saved 18,500 toward a down payment on a house. If he makes 3890 a month, How much can afford to spend on a house?A.) 100,000
B.) 93,369
C.) 111.860
D.) 65,180

Answers

In the first year, Larry can afford to spend D.) $65,180 on a house if he makes a down payment of $18,500 and a monthly payment of $3,890.

What is a down payment?

A down payment is an initial upfront payment that a borrower makes towards paying off the mortgage or loan.

The down payment is based on a percentage of the mortgage amount, for example, 10% or 20%.

Data and Calculations:

Down payment = $18,500

Monthly payment = $3,890

Annual payments = $46,680 ($3,890 x 12)

Payment in the first year = $65,180 ($46,680 + $18,500)

Thus, in the first year, Larry can afford to spend D.) $65,180 on a house if he makes a down payment of $18,500 and a monthly payment of $3,890.
