Step-by-step explanation:
You're correct, the answer is C.
Given any function of the form

, then the derivative of y with respect to x (

) is written as:

In which

is any constant, this is called the power rule for differentiation.
For this example we have

, first lets get rid of the quotient and write the expression in the form

:

Now we can directly apply the rule stated at the beginning (in which

):

Note that whenever we differentiate a function, we simply "ignore" the constants (we take them out of the derivative).
I believe the answer is 11/15 .
Hello!
We know that 1 minute = 60 seconds.
5 minutes = 300 seconds because 60 × 5 = 300
360 seconds would be 6 muinutes. 420 seconds would be 7 minutes. That means 480 seconds = 8 minutes, so 8 minutes have passed.
The equation for line E is x = 8.
This is because the line intersects the x-axis at the point (8,0)
