the file is an example of an exponential graph so look at this example i would say the answerr is b
C is right rjfjdkwjwkwwowowkkskskwwkksskkddje
First we need to convert cm to mm
45 cm = 450 mm
Now our ratio looks like this
60/450
We can divide both by 30 and once we do that our ratio will look like this:
2/15
That means the answer is B
F(x)=-4(8)-5=
F(x)=-32-5=
F(x)=-37
0.3r/0.3=2.1/0.3
r=2.1/0.3
r=7
