Answer:
2.5 * 10^-27.
Step-by-step explanation:
(2 x 10^13)^-2
= 2^-2 x 10^-26
= 1/2^2 x 10^-26
= 0.25 x 10^-26
= 2.5 * 10^-27.
Answer:
Step-by-step explanation:
Given AB with coordinates A(3, -3) and B(1, -1)
Perpendicular bisector passes through midpoint of the segment.
<u>Midpoint of AB has coordinates:</u>
- x = (3 + 1)/2 = 2, y = (-3 - 1)/2 = -2
<u>Slope of AB</u>
- m = (-1 + 3)/(1 - 3) = 2/-2 = -1
<u>Slope of the perpendicular line is:</u>
<u>The equation of the line in point-slope form:</u>
- y - y₁ = m(x - x₁), where m = 1, x₁ = 2, y₁ = -2
- y - (-2) = 1(x - 2) ⇒ y + 2 = x - 2
<u>Converted into slope-intercept form:</u>
