Answer:
The terminal point is Q(0,4)
Step-by-step explanation:
We are given the following in the question:
Initial point of vector, P(1,0)
The terminal point Q lies on the y-axis, thus Q have coordinates of the form:
The magnitude of the vector is
Magnitude is given by:
But since the terminal point is above the initial point, thus,
Thus, the terminal point is Q(0,4)
We are given that popularity of television is inversely proportional to its cost.
let us say popularity of television is represented by "P" and cost of television by "T".
We will use a constant "k" to convert the proportionality sign to equal to (=) sign.
Thus forming the equation :
We are given that 15 customers buy a television that cost $1500.
plugging P=15 and T=1500, finding k,
k=15*1500 = 22500
Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,
P=9
So there will be 9 customers that buy a television which costs $2500.
