Write a function to model the situation. a digital image is reduced or enlarged by dragging the corner. the height to width ratio is always maintained as that the width is 1.25 times the height. write a function to model the area of the image as a function of its height. and you

a(h) = 1.25h²

Step-by-step explanation:

The formula for the area of a rectangle is ...

A = HW . . . . . where H represents the height and W represents the width

If the image has a height of h, then the width is 1.25 times that, or 1.25h. Putting these values into the formula, we have ...

A = h·(1.25h)

A = 1.25h²

In function form, we can write a(h), area as a function of height, as ...

a(h) = 1.25h²

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
