In which of the following functions would it be appropriate to use only positive integers for the domain? select all that apply.
the function c(x) represents the cost for (x) people to attend the movies.
the function m(n) represents the predicted amount of bracelets sold as the price (n) changes.
the function t(q) represents the temperature of water at (q) distance below sea level.
the function p(w) represents the profit of a farmer who sells (w) whole watermelons.
the function h(p) represents the number of person-hours it takes to assemble (p) engines in a factory.

Step-by-step explanation:

People, watermelons, and engines are countable objects, so best represented by positive integers.

Price and distance (elevation) are not restricted to integer values, though we sometimes round them to integer values. Certainly, distance below sea level is usually represented by a negative (not positive) number.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
