Determine whether the sequences are increasing, decreasing, or not monotonic. If increasing, enter 1 as your answer. If decreasing, enter −1as your answer. If not monotonic, enter 0 as your answer.

1. an=1/5n+7
2. an=n-5/n+5
3. an=(√n+5)/7n+5
4. an=cos(n)/5^n

What is the solution set of the quadratic inequality x^2-5< or equal to 0

Prove that quadrilateral is a rhombus.

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
