The U. S Bureau of the census predicted that population of Florida would be about 17.4 million per year until 2015. which of the following linear models predicts the population, y, of florida (in millions) in terms of x, the number of years since 2010. a. y=17.4x + 0.22 b. y= -0.22x + 17.4 c. y= 0.22x + 17.4 d. y= -17.4x + 0.22

step-by-step explanation:

abc

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.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
