Identify the sentence as simple, compound, complex, or compound-complex.

the 49th parallel of north latitude also runs through many other countries, including france, germany, the ukraine, and china.

a. compound sentence

b. compound sentence

c. compound-complex

d. complex

A. Compound Sentence.

Explanation:

The compound sentence refers to the sentence comprising of two independent clauses joined with either a semicolon or a comma. The given sentence exemplifies this category as it justifies the above claim with "The 49th parallel of north latitude also runs through many other countries" as the first clause while "including France, Germany, Ukraine, and China" as the second one. The other options suggest an inappropriate claim as the given example is neither a complex as it does not include dependent clauses nor a compound-complex as that requires a minimum of two independent clauses with a dependent clause. Thus, the first one(A) is the answer.

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
