2. A boat is being pulled into a dock by a rope attached to it and passing through a pulley on the deck, positioned 6 meters higher than the boat. If the rope is being pulled in at a rate of 3 meters/sec, how fast is the boat approaching the dock when it is 8 meters from the dock? Make sure your answer includes units. 3. A girl is flying a kite on a string. The kite is 120 ft. above the ground and the wind is blowing the kite horizontally away from her at 6 ft/sec. At what rate must she let out the string when 130 ft of string has been released? Make sure your answer includes units.

4. Find the Linearization of f(x) = sinx at a = . Provide your answer as L(x) =?
5. Use Linear Approximation to estimate e(-0.01). Provide your answer in 2 decimal places. Do not use a calculator. Show work for credit.
6. Calculate the locations of maximums and minimums of the following functions: Show work in details.
• f(x)=x²-3x+2
f(x)=x¹8x² +3
7. Find the exact x-value where the function f(x) = x + ln (x² - 1) attains a maximum value. An estimated answer or a calculator answer will not earn any credit.
8. Using the Mean Value Theorem and Rolle's Theorem, show that³+x-1=0 has exactly one real root.
9. If f(1) = 10 and f'(x) > 2 for 1 ≤ x ≤ 4, how small canf (4) possibly be?
