Answer: 7.1 feet
Step-by-step explanation: I guessed lol
As seen, the graph is pointing/increasing upwards. This means that the graph is exponentially increasing.
You notice there are significantly more spores at 4th hour than the first, therefore, this is an increasing trend.
Hope I helped :)
1) The scale factor is 0.25 is true.
Step-by-step explanation:
Step 1:
The first figure is dilated to form the second figure. The shape is a rhombus.
It is given that the side length of the first figure is 5.8 and the side length of the second figure is 1.45.
Step 2:
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the side length of the rhombus.
The scale factor 
So the scale factor is 0.25. This is the first option.
I still have absolutely no idea how it got that answer. Just move on and accept that the answer is still wrong no matter what
