Answer: the hight of the plant is the dependent variable bc the independent variable is music being played
hoped this helped (let me know if it did) :)
Answer:
A
Step-by-step explanation:
So we have the piecewise function:

And we want to find f(8).
Since our input value is 8, choose the equation that fits our input.
The first equation demand x to be less than 3. 8 is not less than 3, so we won't use that.
The second equation demand x to e greater than or equal to 3 and less than 8. 8 is <em>not</em> less than 8. So, we won't use that.
The third equation demands x to be greater than or equal to 8. 8 is greater than or equal to 8, so we'll use the third equation.
So:


There're nothing more to do, we're done :)
The answer is A.

Answer:
2/5
Step-by-step explanation:
If we convert 1/2 to tenths we get 5/10. We can subtract that from 9/10 to find out what q equals which will give us 4/10 which is also equal to 2/5
(sorry i'm really bad at explaining but I hope this helps)
Y=8.25x+10
10 is the allowance plus the 8.25 times x which is the hours
ANSWER

EXPLANATION
The given limit is

To evaluate this limit by direct substitution,
We put x=0 in the function.
This implies that that ,

This simplifies to,


This means that as x-values approach zero, the function approaches -1.
