Answer:
You arrive home after driving 3 hours and 40 minutes.
Step-by-step explanation:
Find 1 1/4 on the number line and count back 3/4 (why it is negative) answer is 1/2.
The answer is 6*square rooted*2
Answer:
a) The function is constantly increasing and is never decreasing
b) There is no local maximum or local minimum.
Step-by-step explanation:
To find the intervals of increasing and decreasing, we can start by finding the answers to part b, which is to find the local maximums and minimums. We do this by taking the derivatives of the equation.
f(x) = ln(x^4 + 27)
f'(x) = 1/(x^2 + 27)
Now we take the derivative and solve for zero to find the local max and mins.
f'(x) = 1/(x^2 + 27)
0 = 1/(x^2 + 27)
Since this function can never be equal to one, we know that there are no local maximums or minimums. This also lets us know that this function will constantly be increasing.
Your answer is: Yes, because the sum of the two angles is 180° (the second option).
I hope this helps!
