What is the midpoint between -2-3i and 3+9i

Svetlanka [38]

Answer:

1/2 + 3i is the midpoint between -2-3i and 3+9i.

Step-by-step explanation:

Given the complex number

-2-3i

3+9i

The formula to find the midpoint of two complex number (a + bi) and (c + di) is:

$M=\frac{\left(a+c\right)}{2}+\frac{\left(b+d\right)i}{2}$

$M=\frac{\left(-2+3\right)}{2}+\frac{\left(-3+\left(9\right)\right)i}{2}$

$M=\frac{-2+3+\left(-3+9\right)i}{2}$

$M=\frac{1+6i}{2}$

$M=\frac{1}{2}+3i$

Therefore, 1/2 + 3i is the midpoint between -2-3i and 3+9i.

The numbers 45 28 53 form a pythagorean triple true or false

GarryVolchara [31]

You can verify this by plugging the numbers into the Pythagorean theorem, $a^2+b^2=c^2$ , where c is the hypotenuse (the longest side, in this case 53).

So it would be: $28^2 + 45^2 = 53^2$
The equation is true.
2809 = 2809
