Polynomials are great functions to use for modeling real-world scenarios where different intervals of increase and decrease happen. but polynomial equations and graphs can be trickier to work with than other function types. in mathematical modeling, we often create an equation to summarize data and make predictions for information not shown on the original display. in this activity, you’ll create an equation to fit this graph of a polynomial function.

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: 5/2     2 1/2

step-by-step explanation:

5/2              

5 goes into 2 two times so its 2 and 1/2
