What is the distance between 4-i and -2+3i?

If you're working with complex numbers, then I'm sure you're comfortable with plotting them on a complex-plane ... real part of the number along the x-axis, and imaginary part of the number along the y-axis.

When you look at it that way, your two points are simply two points on the x-y plane:

   4 - i    ===> (4, -1)

   -2 + 3i ===> (-2, 3) .

The distance between them is

   D = √ (difference in 'x')² + (difference in 'y')²

   = √ (6)² + (4)²

   = √ (36 + 16)

   = √ (52)

   =    7.211 (rounded)

The ratio of the sides of a triangle is 8:13:11. If the perimeter of a triangle is equal to 256, what is the length of the longe

There asking what the numbers are by The ratios, what I did was did was multiply by 8 for each number 8•8=64 13•8=104 11•8=88 so now what you do is add up 64+104+88=256 those are your answers if you want to double check you will dived them by 8 so 64/8=8 104/8=13 88/8=11
Hope this helps :-)

You charge people $10 per hour to pick fruits and $8 per hour

Fruits :
Y=10(h)

Flowers;
Y=8(h)

Given: h=6

Fruits:
10(6) = $60

Flowers:
8(6)= $48

Back to the question, how much more from picking fruits?

$60 - $48 = $12 more picking fruits.

Hope this helps!
