Jeffrey drew a square field.

The length of the square field is 20 m.

Now he increased the length by 5.

So the new length is 20 + 5 = 25 m.

He also decreases the width by 5 m.

Hence the new width shall be 20 - 5 = 15 m.

The formula for the area of the rectangle is

= length × width

= 25 × 15

= 375 m²

The area of the rectangle after increasing the length by 5 m & decreasing the width by 5 is 375 m².

Is this an example of a horizontal asymptote?
8_murik_8 [283]

Answer:

Step-by-step explanation:

Hi there,

The graph indicated is showing a horizontal asymptote. In fact, it is showing both a horizontal and a <em>vertical </em>asymptote.

To tell which type it is, notice where the graph "shoots off" and almost forms an imaginary straight line in one direction. Using this logic, the horizontal asymptote will be exactly horizontal, parallel to x-axis, and vertical asymptote will be exactly vertical, parallel to y-axis.

With this graph, we notice the horizontal asymptote is at y=0, where the x-axis is. The vertical asymptote is bit more difficult to determine graphically, but can definitely say it is past x=-10. We could determine it if we had the function, but that is not necessary for this question.

Study well, and persevere. If you liked this solution, leave a Thanks or give a rating!

thanks,
