Given f(x) = x3 + kr + 9, and x + 1 is a factor of f(x), then what is the value of
k?

the answer i believe is 27 units.

step-by-step explanation:

the answer is -1 for this question

step-by-step explanation:

8.3 and the 3 is repeating

hope this .

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.
