• A Woman biker (leader of the local chapter of Heck's
Angels) is driving along the highway at 80.0 km/h, in
a 60.0 km/h speed zone. She sees a police car ahead,
so she brakes and her bike accelerates at
-8.0 km/h/s. How far along the road will she travel
before she is at the legal speed limit?

99

step-by-step explanation:

this is false ^.^ lol

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

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.
