2d. To calculate the air pressure, the volume occupied by the air is assumed constant. Why is this assumption incorrect

This assumption is incorrect as the volume that is occupied by the air is decreasing as the flask is not completely airtight. Also, the volume starts decreasing as the ethanol is injected into the flask.

Explanation:

To calculate the air pressure, the volume occupied by the air is assumed constant. This assumption is incorrect as the volume that is occupied by the air is decreasing as the flask is not completely airtight. As a result, the air pressure values wouldn't be exact. As the volume decreases, vapor pressure also decreases. Also, the volume starts decreasing as the ethanol is injected into the flask.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
