Step-by-step explanation:
To find the derivative, notice we have a function 1/x inside of another function, ln(x)
We use what we call the chain rule,
It states that
derivative of a '
Here f is ln(x)
f is 1/x
So first, we know that
so
We know that
So we have
Answer:
of an hour = 1 1/5 hour = 72 minutes
Step-by-step explanation:
The x-intercept will be the value of x when y=0. The solutions to (x+1)(x+2)=0 are -1 and -2 since we can substitute them in to have one of the values in parentheses equal to zero, so our x-intercepts are (-1, 0) and (-2, 0). The y-intercept is the value of y when x=0, or (0+1)(0+2)=2. Therefore, the y-intercept is (0, 2).
First term = 2(1) - 3 = 2 - 3 = -1
