Identify the sentence that correctly uses singular and plural nouns. a. while you are at the grocery store, will you pick up two loafs of garlic bread for dinner?    b. for her wedding shower, erin received a beautiful set of knifes.   c. the farm has thirteen sheep, twelve cows, and one bull.   d. the kindergartener listed his heros as his mother, his father, his grandparents, and fireman.

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

can you elaborate on what the question asks?
