It is not linear because x is raised to the second power. Therefore it is not straight and would be kindof like a rainbow cut in half on the graph..

Rishan is building a number 3091 using Place-value blocks. There are no thousands block. How many hundreds blocks can he use ins
satela [25.4K]

Given:

The number is 3091.

To find:

The number of hundreds blocks if there are no thousands block.

Solution:

The given number is 3091.

It can be written as:

3091=3000+0+90+1

3091=3\times 1000+0\times 100+9\times 10+1\times 1

3091=3\ Thousands+0\ Hundreds+90\ Tens+1\ Ones

There are no thousands block. So,

3000=30\times 100

3000=30\ Hundreds

Therefore, the number of hundreds blocks in 3091 is 30.

(intro) Slope is change in y divided by change in x (axes). Here, the y axis is depth and the x axis is hours. So, the slope is change in depth between any two points, divided by the change in hours between the same points. The slope of this line is half a foot depth divided by 2 hours.
a) So, the slope is 0.5 / 2 = 0.25, or 1/4.
b) The graph shows a constant rate of change because the line is straight (it increases at the same speed. If the line was curving, it would not be a constant rate of change).
c) Yes, because the line has a constant rate of change now.
