D must equal 20
when p=3, d= 5 and then p=12 which is an increase of 4 times therefore
when p=12, d= 5x4=20

What is the distance between P(-3,-25) and Q(50,-2)

Karolina [17]

$Dist = (x2-x1)^{2} + (y2-y1)^{2}$

above is the distance formula, plugging your numbers from P(x1,y1) and Q(x2,y2).

$Dist = \sqrt{(50-(-3))^{2} + (-2-(-25))^{2} }$
or $\sqrt{ 53^{2} + 23 ^{2} }$

Rewrite −1 + 2i in polar form.

raketka [301]

The length of the radius would sqrt(1+4), or sqrt(5).
2
The angle would be in Quadrant II and would be arctan ------ , or arctan (-2).
-1

Find this angle using a calculator or table.

Then you end up with -1+2i = sqrt(5) angle arctan(-2). The angle would be + and measured from the + horizontal axis.
