Find the value(s) of k so that the points (-3,2) and (9, k) are 13 units apart.

k = 11

Step-by-step explanation: math

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
