Question

find the ratio in which the line segment joining the points
A [3,8] andB [-9, 3] is divided by y axis​

Answer 1

Answer:

a man rows upstream in still water at 3 km/h and back to the same place at 5 km/h he takes 48 minutes altogether. how far upstream did he go?Dan invests £22000 into a Saving accounts.The bank gives a 5% compound interest for the first 3 Years and 4% .Thereafter. How much will Dan have after 7 Years to the nearest pound

Answer 2

Answer:

Let C be a point on Y-axis which divides seg AB in the ratio m : n. Point C lies on the Y-axis ∴ its x co-ordinate is 0. Let C = (0, y) Here A (x1,y1) = A(3, 8) B (x2 , y2 ) = B (-9, 3)

see the attachment for answer

∴ By section formula, Y-axis divides the seg AB in the ratio 1:3.
