D to show the culture of white South Africans

Explanation:

Hally initially tells this joke so that she can show Sam and Willie that the relationship between him and his dad wasn't always bad. However, the joke really shows the culture of white South Africans. Telling this joke shows the naivete of Hally in how he views the joke as appropriate to tell around Sam and Willie. This shows the culture of white South Africans and how they viewed black people.

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

the answer can be "credo" it means to believe = the word credo means "an official statement of beliefs"
