If (a-bi)^2 = 13 - 12i, what is the product of a and b?

VARVARA [1.3K]

Answer:

$\large \boxed{\sf \ \ \ a\cdot b= 6 \ \ \ }$

Step-by-step explanation:

Hello,

$(a-bi)^2 = 13 - 12i\\\\ a^2+(bi)^2-2abi = 13-12i\\\\a^2-b^2-2abi=13-12i$

Imaginary term must be the same so

-2ab=-12

2ab = 12

ab = 12/2 = 6

So the product of a and b is 6

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Dist from slide to fountain: 200 ft, because they are 2 grid spaces away from each other (y axis, coordinate (-2, 0) to coordinate (-2, -2))

dist from fountain to swings is 700 ft, because they are 7 grid spaces away from each other (x axis, coordinate (5, -2) to (-2, -2))

Solve 3m- 5h = 45 for h

Masja [62]

$3m- 5h = 45\\5h=3m-45\ /:5\\h=\frac{3m-45}{5}\ \ \ or\ \ \ h=\frac{3}{5}m-9$
