Answer:
8.65
Step-by-step explanation:
Use a calculator and type "48.55 / 5.6"
D is a function because there are no repeated x values
for example b is not a function because we have (0,-7) and (0,-9)
Answer: A
Step-by-step explanation:
The ratio is simply 2:5
You are comparing the two times
Answer:
TRUE. We need to use the chain rule to find the derivative of the given function.
Step-by-step explanation:
Chain rule to find the derivative,
We have to find the derivative of F(x)
If F(x) = f[g(x)]
Then F'(x) = f'[g(x)].g'(x)
Given function is,
y =
Here g(x) = (2x + 3)
and f[g(x)] = 

y' = 
= 
y' = 
Therefore, it's true that we need to use the chain rule to find the derivative of the given function.
