If the Hubble constant is 70 km/s/max, how far away is the quasar that has an apparent recession of 45,000 km/s? Use the Hubble law v=h0d where v= velocity of galaxy, in km/s, h0=Hubble constant, measured in km/s/mpc, d= distance of galaxy, in mpc, what percentage of light is this? (It’s the first question in the Picture)

step-by-step explanation:

step-by-step explanation:

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.

answer: the answer is ann
