Providing sources for a review is important because it shows the reader that a. the reviewer will always agree with the reader’s assessment. b. the reviewer is speaking from an informed viewpoint. c. the reviewer is speaking from a biased viewpoint. d. both a and c

The correct answer is: B) The reviewer is speaking from an informed viewpoint.

The sources refer to the place the author gets the information he is giving us. They are divided in primary, secondary and tertiary sources For example, if the writer gives a statistic about the number of deaths caused by cancer his source could be the World Health Organization. In this case by providing sources to the review, the author can show the reader that the proper research has been done, they can also give a reference on where to look if they want more information about the topic.

In this case by giving the references the reader can be sure that the author didn't invent everything or give false information as it can be compared. The more sources he gives the more informed he appears to be.  

the answer is somber

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
