Natalie is in the business of manufacturing phones. She pays a cost of $50 per phone produced for materials and labor and also must pay a daily fixed cost of $900 to rent
the building and equipment. Make a table of values and then write an equation for C,
in terms of p, representing total cost, in dollars, of producing p phones in a given day.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
