Consider the formula r=v/ct, where r represents the rate of infection, v represents the number of viruses in a cell, c represents the number of cells and t represents time and is represented in hours. select an appropriate measurement unit for rate of infection. a) viruses/cell*hours b) viruses*hours/cells c) cell*viruses/hours d) cells*hours/viruses

A) Viruses/cell*hours

Step-by-step explanation:

Here, R represents the rate of infection, V represents the number of viruses in a cell, C represents the number of cells and t represents time ( In hours).

Also, the given formula,

Hence, option A is correct appropriate measurement unit for rate of infection.

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

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.
