The table shows the number of cars manufactured in thousands by a company for selected years. Use a calculator to write a quartic model for the number of cars manufactured in a given year since 2000. Then use the model to estimate the number of cars manufactured in 2011. Answers:
f(x) ≈ 0.808x3 + 21.028x2 − 187.403x + 373.988
The estimated number of cars manufactured in 2011 is about 218.

f(x) ≈ 0.135x4 + 3.807x3 − 36.285x2 + 118.073x − 213.2
The estimated number of cars manufactured in 2011 is about 215.

f(x) ≈ 0.135x4 − 3.807x3 + 36.285x2 − 118.073x + 213.2
The estimated number of cars manufactured in 2011 is about 215.

f(x) ≈ 0.808x3 − 21.028x2 + 187.403x − 373.988
The estimated number of cars manufactured in 2011 is about 218.

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.
