The components of vector A are (10.5,15.2). What is the magnitude of the vector?
​

i believe it's a.

i'm not sure on this one, most likely correct.

the correct answer would be the third option

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
