Math Problem Statement

Write the component form of the vector that describes the straight-line path from the car’s current position C to its intended destination D

Write the component form of the vector that describes the straight-line path from the car’s current position C to its intended destination D.

Solution

To write the component form of the vector describing the straight-line path from the car's current position C(4,12)C(4, -12) to its intended destination D(10,15)D(10, -15), we use the formula for the component form of a vector between two points C(x1,y1)C(x_1, y_1) and D(x2,y2)D(x_2, y_2):

Vector CD=(x2x1,y2y1)\text{Vector } \overrightarrow{CD} = (x_2 - x_1, y_2 - y_1)

Substituting the coordinates of C(4,12)C(4, -12) and D(10,15)D(10, -15):

CD=(104,15(12))=(6,3)\overrightarrow{CD} = (10 - 4, -15 - (-12)) = (6, -3)

Thus, the component form of the vector from CC to DD is CD=(6,3)\overrightarrow{CD} = (6, -3).
