Show that the equation x^3 + x -3 =0 has a solution between 1 and 2. That is the only information given

Step-by-step explanation:

Given that:

Since the given function is equal to zero, then the function :

where;

and

Thus; f(1) < 0 and f(2) > 0

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.

he kicked it up? is this the answer ?
