There were 23.7 million licensed drivers in California in 2009 and 22.76 million in 2004. Find a formula for the number, N, of the licensed drivers in the US as a function of t, the number of years since 2004, assuming growth is a) Linear
N(t) = 0.188t + 22.76 million drivers

b) Exponential
N(t) =

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

correct answer:

b.(19,-2)

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.
