Answer:
To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.
To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.
Step-by-step explanation:
Mohammad will have collected T cards after m months, given that he buys 5 cards each month and he started with no cards.
The relationship describing this situation is

When
then
cards.
When
then
cards.
To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.
To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.
Assuming width=diameter
diameter/2=radius
area=hpir^2
w=d=2
d/2=2/2=1=r
h=6
area=6pi1^2
area=6pi1
area=6pi
aprox pi=3.141592
area=18.85 cm³
if you do not have a Unit Circle, this is a great time to get one, you can find many online just do a quick search for "unit circle".
Check the picture below.
6.7 x -2.3
You would multiply this just like any other multiplication question.
There is some work of course, but I'm not going to write it out here...
You are going to end up with -15.41, which is already rounded to the nearest hundredth.
Hope this helped :)
