I think all of your answers should be correct, but i think you should label them specifically (ex. 600$ in stock) and also maybe on the first two questions say that dorris miscalculated by 125$ and like explain how a bit better
Answer:
c
Step-by-step explanation:
because you add up all the days then you get the total
The correct answer would be B. 2/(x + 8)
When you are completing composite functions, you place the entire second function in for x in the first function. Since the letter f comes first in f o g. then we start with the f(x) equation.
f(x) = 2/x
Now since g comes next, we take the entire equation for g(x) and substitute it in.
f o g = 2/(x + 8)
This is answer B.
Answer: 28.275cm^3
Step-by-step explanation: The density equation is mass/volume, and you can rearrange the equation to figure out what the volume is. By rearanging the equation, you get that volume= mass/ density. So 11.31/0.40=28.275cm^3
