Identify the incorrectly punctuated sentence. a) remember to turn off the lights and lock the door. b) on our trip we will be driving, and taking the train. c) fred will feed the cat, and rose will pick up the mail d) the weekend was short but fun. identify the incorrectly punctuated sentence. a) be careful not to mix household cleaners, for that can be dangerous. b) i will wish the windows, and you clean the floors. c) the windows have been washed, but they still look dirty. d) this product is, for cleaning glass.

B is incorrectly punctuated because you should not use a comma before and if you are only talking about two qualities. This rule also applies to proper names, verbs, ordinary nouns and anything else. Therefore, the sentence would be correct if it read: "On our trip we will be driving and taking the train". No comma between the two elements in the coordination.

What is more, in the second row of examples D is also incorrectly punctuated. There should be no comma between the verb and the preposition.  You shold not use a comma to separate a verb from its direct object unless the words between them require special punctuation.

ion know   my guy ask god or some frfr

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
