Can Lady Macbeth be considered the fourth witch of the play? She certainly knows how to make an entrance. Look at how her character develops in Act 1 Scene 4 to explain your reasoning.​

Lady Macbeth can be considered the fourth witch in Macbeth to a great extent. Firstly, Lady Macbeth is wicked. She calls upon “thick night and pall thee in the dunnest smoke of hell” so that her “keen knife” will be unable to see “the wound it makes”.

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
