A segment in the coordinate plane has an endpoint with coordinates (1,2) and midpoint with coordinates (4,3). What are the coord

Serga [27]

Answer:

(7,4)

Step-by-step explanation:

midpoint formula (x1+x2)/2 , (y1+y2)/2

Look at x and y for the endpoints separately

midpoint x value = ( 1 + x)/2

4= (1 + x)/2

8 = 1 + x

x = 7

midpoint y value = (2 + y)/2

3 = (2 + y)/2

6 = 2 + y

y = 4

endpoint (x,y) = (7,4)

Use the pythagorean theorem to find the distance between from A(5, -3) to B (6,0)

Orlov [11]

C. 3.16 is the right answer

Step-by-step explanation:

The distance formula used in coordinate geometry is derived from the Pythagorean theorem.

The distance formula is give by:

$d=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}$

Here (x1,y1) are the coordinates of first point and (y1,y2) are the coordinates of second point

Here,

(x1,y1) = (5,-3)

(x2,y2) = (6,0)

Putting the values in the formula

$AB = \sqrt{(6-5)^2+(0-(-3))^2}\\=\sqrt{(1)^2+(0+3)^2}\\=\sqrt{(1)^2+(3)^2}\\=\sqrt{1+9}\\=\sqrt{10}\\=3.16\ units$

The distance between two points is 3.16 units.

Hence,

C. 3.16 is the right answer
