Answer:

15

Step-by-step explanation:

Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:

(y2 - y1)/(x2 - x1)

=> Rate of change of the line passing (1,15) and (3,45):

(45 - 15)/(3 - 1) = 30/2 = 15

Triangle QRS has medians QU, RV, and ST. If the measure of segment RW is 18 meters, what is the length of segment RV?
rodikova [14]

Answer: RV = 27 meters

Step-by-step explanation: <u>Median</u> is a line which unites a vertice and a midpoint of the opposite side. The point where, in a triangle, the medians intersect is called <u>Centroid</u>. The centroid divides the median in a ratio of 2:1, so <em><u>Centroid</u></em> <em><u>Theorem</u></em> states that the centroid of the triangle is at 2/3 of a distance from the vertex to the midpoint of the sides.

The attached figure shows the medians and centroid.

RW and WV are components of RV, the median.

If RW is 18 and following the theorem:

RW = \frac{2}{3}.RV

RV = \frac{3}{2}. RW

RV = \frac{3}{2}.18

RV = 27

The median RV measures 27 meters.
