Determine el radio vector del punto medio del segmento que se forma al unir los puntos (-8, 7) y (6, 3).
tiny-mole [99]

Answer:

The radius vector is (-8, 7) and (-1 , 5).

Step-by-step explanation:

Determine the radius vector of the midpoint of the segment that is formed by joining the points (-8, 7) and (6, 3).

The end points are (- 8, 7) and (6, 3) .

The mid point is given by

x = \frac{x' + x''}{2}\\\\y = \frac{y' +y''}{2}\\\\x =\frac{- 8 + 6}{2}=-1\\\\y = \frac{7+3}{2} = 5

So, the radius vector is (-8, 7) and (-1 , 5).

Jean climbed 2/3 of the distance to the top of the cliff as shown on the number line. Terry climbed 1/3 of the distance less tha
Goshia [24]

Answer:

See Explanation

Step-by-step explanation:

Given

Jean = \frac{2}{3}

Terry = \frac{1}{3}

Steve = \frac{1}{5}

Required

Represent them on number line

Start by getting the LCM of the denominators of the three fractions;

The denominator are: 3 and 5

LCM = 15

This means that, the number line will be divided into 15 partitions;

Next, we get the position of each fraction as follows;

Jean = \frac{2}{3} * 15

Jean = \frac{30}{3}

Jean = 10

<em>Jean will be represented on the 10th point</em>

Terry = \frac{1}{3} * 15

Terry = \frac{15}{3}

Terry = 5

<em></em>

<em>Terry will be represented on the 5th point</em>

<em></em>

Steve = \frac{1}{5} * 15

Steve = \frac{15}{5}

Steve = 3

<em>Steve will be represented on the 3rd point</em>

<em></em>

<em>See Attachment for number line</em>
