1. sally did an experiment. she started out with 250 bacterial cells. she found out that the hourly growth rate of the bacterial cells was 4.1%. using the exponential growth formula y=b(1+r)^r, sketch the graph that represents the situation. label the axis, y-intercept, and the point that represents the project bacterial population 25 hour from the time sally started the experiment.

i not know

step-by-step explanation:

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.
