Anaval engineer uses the function, p, to analyze the effects of water pressure on submarines. the function p(d) measures the pressure exerted by water, where d represents the depth of the water in meters. which of the followin could be a possible domain?

a. d is the set of all integers
b. d is the set off all integers where d is greater than 0
c. d is the set of all rational numbers
d. d is the set of all rational numbers where 0 is less than or equal to d less than or equal to the depth of the sea floor

The function that the naval engineer uses related P (pressure) and d (depth of ocean).

Is there any restriction on the domain ( d: depth of the ocean)? Yes!

The domain would be from 0 (at sea level or 0 depth) until the depth of the ocean (which is not infinite). Hence, we can write:

Choice D is the correct one.

ANSWER: D

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
