You are given the function 
Express t:

This expression gives the month t in terms of the price p.
If a^2+b^2=c^2 then it's a right triangle
If c^2>a^2+b^2 then it's obtuse
If c^2< a^2+b^2 then it's acute
16*35=560, I used multiplication
Answer:

Step-by-step explanation:
First plug the equation of y into the equation of z, so that we get their intersection:
We plug

Into: 
So, we get:

Then we set
And plug that in the equation
and the one we just got for z.
So that we get:

Therefore, the vector function that represents the curve of intersection is:
