Writing Prompt:
There are many ways in which new technology is changing in the 21st century. Think about the
information in both passages. Then, write an informational essay in your own words explaining at least
two unique challenges that arise with the use of robotic technology, especially underwater. Be sure to
use information from BOTH articles.
Articles: “Scientists build a robotic fish to spy on ocean life” and “U. S. military group tried out fish as underwater spies.”

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

the anecdote makes readers feel sorry for the man’s lack of heritage, then reminds readers that the man has an equally valuable heritage.

the correct answer is: d
