Question

If the distance between (b, -5) and (-2, 2) is 13. Find the value of



b. Solution

Answer 1

Answer:

Step-by-step explanation:

Ohk so ...

GIVEN DISTAMCE BETWEEN (B,-5) AND (-2,2)IS 13

THEN USING THE DISTANCE FORMULA↪√(X2-X1)sq + (Y2-Y1)sq

PUTING VALLUES

13=√(-2-B)sq +{2-(-5)}sq

13=√4+Bsq+4B+(2+5)sq

13=√4+Bsq+4B+49

13=√Bsq+4B+53

(13)sq=Bsq+4B+53

169-53=Bsq+4B

116=Bsq+4B

0=Bsq+4B-116

USING QUADRATIC FORMULA

- B+_√Bsq-4ac

____________

2a

-4+_√(4)sq-4(1)(-116)

_______________

2(1)

-4+_√16+464

___________

2

-4+_√480

B=___ _ ______
