In what way does research add clarity during discussions
A. It allows students to defend their arguments with their own opinions
B. Allows students to argue their points without reading notes
C. It allows students to state their ideas clearly with evidence
D. It allows students to show how smart they are

C

Explanation:

Let's use the elimination process. It would not be A because research is not opinions, it is facts. It would not be B because that answer is simply absurd. It would not be D because that also makes no sense. So its C.

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
