a. Sentence fragment

Explanation:

A sentence fragment is an incomplete sentence that could possibly be a part of another sentence. We can determine the sentence is not grammatically correct if it lacks a subject or a verb.

“Maria's long dark hair.” is the statement that lacks the verb. There is not an action performed by or on Maria’s hair. This is just partly information about the state of Maria’s hair, and not the full sentence.

For example, the full sentences would be:

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
