Find the distance between A (4, 6) and B (9, 7). Write your answer as a radical and as a decimal rounded to the nearest
Stells [14]

The distance between A (4, 6) and B (9, 7) is √26 or 5.1.

<h3>How to find the distance between two points?</h3>

Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;

d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }

Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;

d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }

So the distance between A (4, 6) and B (9, 7) will be

d = \sqrt {\left( {4 - 9 } \right)^2 + \left( {6 - 7 } \right)^2 }

d = √26 = 5.099

Rounded to nearest tenth ⇒ 5.1 units.

Hence "The distance between A (4, 6) and B (9, 7) is √26 or 5.1".

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)
