Which situation results in a final value of zero ? (A) the overall change in temperature when the temperature goes from -10 F to 10 F (B)the total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars (C) the overall change in altitude of a hot air balloon after rising 21 kilometers from sea level (D) the total distance a person travels when he bikes 3.1 miles to school and then bikes 3.1 miles back home

(B)the total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars

Step-by-step explanation:

Let's analyse this using profit and loss formulas.

Profit = Cost price - selling price

In this case,:

Cost price = $2.25

Selling price is $2.25

Profit = ??

Let's invoke the formula:

Profit = Cost price - selling price

Profit = $2.25 - $2.25

Profit = $0

Therefore, the answer is (B)

The total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
