Where did the proto-indo-european people come from?
a)west asia
b)eastern europe
c)we do not know for sure.

The correct answer is B) Eastern Europe.

The Proto-Indo-European people came from Eastern Europe.

These ancient people spoke a language with the same name and were the ancestor of many European languages. Scientists think that they lived during the Neolithic Age when humans started to learn agriculture techniques. They inhabited the territories of the Caspian region, which is modern-day Russia and Ukraine.

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 think the answer is either c or d

im thinking d might make more sense though

sorry if im wrong
