Identify the correct relationship between the main idea and the sub ideas. A. things to do before the first day of school B. reasons why the first day of school is important C. what students learn on the first day of school D. effects of the first day of school on students

c. what students learn on the first day of school.

It would be things to do before skl starts.

Explanation:

You get supplies etc before skl.

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

i would need the dialogue to answer this.
