H(x) = -(x + 11)^2+1 1) What are the zeros of the function?
Write the smaller & first, and the larger x second.
smaller x =
larger x =
2) What is the vertex of the parabola?

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

60: 45 =12: 9 =4: 3 so the answer is 4: 3

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
