Aflow is described by velocity field v =ati +bj, where a = 0.4 m/s 2 and b = 2m/s. at t =2 s, what are the coordinates of the particle that passed through point (2, 1) at t =0? at t =3 s, what are the coordinates of the particle that passed through point (2, 1) at t =2 s? plot the pathline and streakline through point (2, 1) and compare with the streamlines through the same point at the instants t =0, 1, and 2 s.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
