1. the graph shows the amount of total rainfall at each hour. what was the total rainfall amount after 3 hours? a. 3 inches b. 2 inches c. 0.5 inches d. 1 inch

B. 2 inches

Step-by-step explanation:

The question is incomplete, please remember to attach the graph when the question requires it.

Assuming the graph is the attached, where the x-axis represents the time in hours and the y-axis the amount of rainfall in inches. We just have to search for an specific hour and find the amount of rainfall that corresponds to it.

For example, according to this graph the total amount of rainfall after 3 h is approximately 2 inches.

2 inches

Step-by-step explanation

Check attachment for diagram.

According to the graph given, it can be seen that the x axis is the time axis and the y axis is the total rainfall.

To determine the total rainfall amount after 3 hours, we will have to locate time at 3hours on the x axis and trace it up to the straight line, then trace it perpendicular to the y axis to know the total rainfall at t = 3.

Based on the diagram, The total rainfall after 3hours is 2inches.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
