First you must distribute the 1/4 to get
: 1/2x^2-3=15
then you have to add three to both sides so it become
: 1/2x^2=18
then divide by 1/2 to get
:x^2 =36
then take the square root to get a final answer of
:x=6

Find the distance between w=1+2i and z=3-i

AlladinOne [14]

Answer:

The distance between w=1+2i and z=3-i is 3.61

Step-by-step explanation:

We need to find the distance between w=1+2i and z=3-i

The formula used is: $Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have $x_1=1, y_1=2, x_2=3, y_2=1$

We will use only real numbers and not i for calculating distance.

Putting values and finding distance

$Distance=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\Distance=\sqrt{(1-3)^2+(-1-2)^2} \\Distance=\sqrt{(-2)^2+(-3)^2} \\Distance=\sqrt{4+9} \\Distance=\sqrt{13}\\Distance=3.61$
