If the distance between the point (8,p) and (4,3)is 5 then find the value of p |
| Answer» P= 6Step-by-step explanation:A=(8,p) &B= (4, 3) & AB = 5(8,p) &B= (4, 3) & AB = 5BY DISTANCE formula(8,p) &B= (4, 3) & AB = 5By distance formulaAB = √(x1 -x2)^2 + ( y1- y2)^2 5 = √(8-4)^2 + (p - 3) ^25 = √4^2 + p^2 +9 -6p5 = √16 + 9 +p^2 - 6pSquaring on both side 25 = 16 +9 + p^2 -6p25 = 25 +p^2 - 6p25-25 = p (p-6) 0 = p (p-6) 0 = p-66 =P | |
