What is the central idea of there was always an important piece missing for his inventions. he needed batteries to power his homemade devices. kelvin did not have the benefit of a science education at school. yet, he figured out how to make a battery using soda, metal, and tape. these are ingredients he found at a what is the central idea of neighborhood dump! with this battery, the possibilities for his inventions were endless.

explanation:

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
