What is the most accurate representation of the area of a plot measuring 11.7 cm by 15.4 cm? 54 cm2 54.2 cm2 180.2 cm2 180.18 cm2 pl

If the plot is rectangular, the area is the product of the length and width, so looks like it is probably

... A = LW = (11.7 cm)×(15.4 cm) = 180.18 cm²

Of the choices listed, the value that most accurately represents this is ...

... 180.18 cm²

The perimeter of the rectangular plot would be accurately represented as 54.2 cm (not cm²).

Without any real guide as to the geometry, we can only speculate what the given measurements are. They could be axes of an ellipse, height and base of a triangle, or any number of other geometric descriptors. "A plot" is pretty non-specific as to shape.

the range of a function is the range of y-values for which it is defined, or exists. given that we are only looking at the y-values, we can already discount the first two answers as they deal with the domain of the function (range of x-values).

now, what we need to do is find the smallest and highest y-values for which the function is defined. if you'd like, you could take a ruler and start at the very bottom of the graph, find the lowest point, then move the ruler higher and higher until you reach the highest point. doing so either in your head or with an actual ruler, we can see that the lowest y-value is -5 and the highest y-value is -1.

the question now remains as to whether they are included in the range (fourth answer) or excluded (third answer). the key here is to recognise whether they are marked with an open or a closed circle. since both (-2, -5) and (2, -1) are marked with a closed circle, they are points that exist on the graph and are thus included in the range (note that if they were marked with an open circle like (4, -2) then that would signify that there is a break in the graph at that point).

thus, the fourth answer, (y | -5 ≤ y ≤ -1), is correct.

also note that usually it is good practice to scan your eye inbetween the highest and lowest point for any breaks in the graph - we do have one here at (4, -2), however -2 is still included in the range because there is another point that is included in the graph with the same y-value, ie. point (1, -2).

i hope that but if you require any further explanation don't hesitate to comment below.
