A speech on truth advocates (Nelson mandala)

"I Am Prepared to die" is the name given to the three-hour speech given by Nelson Mandela on 20 April 1964 from the dock of the defendant at the Rivonia Trial. The speech is so titled because it ends with the words "it is an ideal for which I am prepared to die". The speech is considered one of the great speeches of the 20th century, and a key moment in the history of South African democracy

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
