Answer: 18
Step-by-step explanation:
2 degrees per hour
9 hours
1hour = 2 degrees
2hours= 4 degrees
3hr= 6 degrees
4hr= 8 degrees
5hr=10 degrees
6hr= 12 degrees
7hr= 14 degrees
8hr= 16 degrees
9hr= 18 degrees
So you are basically doing 2x9 to get your answer

Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%
3 I think because it has three side
I might get it wrong but I’m just trying
