    Understanding Hurricane Warnings & Damage Potential Along the Gulf Coast

    I think I figured it out. The hurricane warning area is larger than the area forecasted to get hurricane force winds because there's still considerable uncertainty as to the exact landfall location of the Hurricane.Assuming that the hurricane does make landfall exactly where predicted,the most...

    Understanding Hurricane Warnings & Damage Potential Along the Gulf Coast

    Assume that Hurricane Don forms into a category 1 hurricane and is positioned in the Gulf of Mexico as shown in the figure below. The 24 hour forecast is for Don to make landfall at the Texas/Louisiana border in 24 hours as a category 2 storm. (The states of Texas and Louisiana are labeled with...

    Air temperature and relative humidity

    In sauna rooms, people spend time in conditions of air temperature over 90° C (194° F) with a relative humidity near 10%. However, if you stick your arm into liquid water that is at a temperature of 90° C (194° F), you will be severely burned in less than one minute. Give two reasons why...

    Why does air pressure decrease with altitude?

    At ground level, the air pressure measured with a barometer is 1000 mb. The barometer is lifted upward by a weather balloon. When the balloon reaches 2 km above the ground, the measured air pressure is 800 mb. Explain why the air pressure decreased. After the balloon goes up another 2 km (now 4...

    Exponential distribution word problem

    The Information Systems Audit and Control Association surveyed office workers to learn about the anticipated usage of office computers for holiday shopping. Assume that the number of hours a worker spends doing holiday shopping on an office computer follows an exponential distribution. a) The...

    Analyzing f(x) Graph: Identifying Points and Derivatives

    Okkk I think that makes better sense to me. I did them again and got D for f 'x>0 and C for f 'x=0

    Analyzing f(x) Graph: Identifying Points and Derivatives

    I read above that " f'(x) is the slope at x." by at X I mean its right on the x-axis

    Analyzing f(x) Graph: Identifying Points and Derivatives

    ^^ I meant H. and i think point G is f '(x)=0

    Analyzing f(x) Graph: Identifying Points and Derivatives

    Alright, so would the answer be point G, which is E)none of these for f ' (x) >0 since at G the slope is at X

    ohhh..so its 0 when the graph doesn't go through point 4.which is D
