Which quadratic function in vertex form has a vertex at (5, 12) and passes through the point (8, 9)? y=13(x−5)^2+12

y=−13(x+5)^2+12

y=−13(x−5)^2+12

y=13(x+5)^2−12

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

the correct answers are 1, 2, 4, and 5! i just got it right!

y - 25 = 2 ( x - 10 ) should be the answer
