How does a referee signal that a game has commenced?

A forward movement is made with both arms, indicating the fight of the ball in relation to the referees body. The signal must commence with both hands on one side of the body and finish with both hands directly in front of the body,with both elbows straight at chest height.

Explanation:I play baseball And I know how it goes!

you do this because a real teammate puts the team first

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
