Ответ:
Option A is correct.
True.
Explanation:
Inverse variation states that a relationship between two variables in which the product is a constant.
If one variable increases then the other decreases in proportion so that the product is unchanged.
If y is inversely proportional to x , the the equation is of the form
; [1] where k is the constatnt variation:
Here, y= Height and x =width
then from the figure;
For points (2, 30)
Substitute the value of x =2 and y =30 in [1];
or
k =60
for point (5,12)
Substitute the value of x =5 and y = 12 in [1]
or
k =60
Similarly, for others point also k = 60
Therefore, we can see that the constant of variation in the given figure is k =60.
Yes it's True, because the figure in the graph of the dimension of rectangle whose adjacent side lengths exhibit inverse variation.
