What is the length of segment xy?

4.5 units
/45 units
/53 units
9 units

The correct option is (C) √53 units.

Step-by-step explanation:  We are given to find the length of the line segment XY in the graph.

We know that the length of a line segment is equal to the distance between its end points.

DISTANCE FORMULA: The distance between two points with co-ordiantes (a, b) ad (c, d) is given by

From the graph, we note that

the co-ordinates of the point X are (-4, 0) and the co-ordinates of the point Y are (3, 2).

Therefore, the distance between the points X and Y is given by

So, the length of the line segment XY is √53 units.

Option (C) is correct.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
