Vectors are used in computer graphics to calculațte the lengths of shadows over flat surfaces. The length of an object can sometimes be represented by a vector a If a light source is shining down on the object, then the length of its shadow on the ground will be equal to the absolute value of the component of the vector a along the of the ground, as shown in the figure. Compute the length of the shadow for the specified vector a if the ground is level. (Round ygur answer to one decimal place.) a = (1.3, 8.9)

Question
Transcribed Image Text:Vectors are used in computer graphics to calculate the lengths of shadows over flat surfaces. The length of an object can sometimes be represented by a vector a If a single
light source is shining down on the object, then the length of its shadow on the ground will be equal to the absolute value of the component of the vector a along the direction
of the ground, as shown in the figure. Compute the length of the shadow for the specified vector a if the ground is level. (Round ygur answer to one decimal place.)
a = (1.3, 8.9)
