Use Table 1.6, which gives values of v = r(s), the eyewall wind profile of a typical hurricane.?
The eyewall of a hurricane is the band of clouds that surrounds
the eye of the storm. The eyewall wind speed v (in mph) is a
function of the height above the ground s (in meters).

a) Evaluate and interpret r(300).
At what altitudes does the eyewall windspeed appear to
equal or exceed 116 mph?
c) At what height is the eyewall wind speed greatest?
b)

Aprojectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. after how many seconds does the projectile take to reach its maximum height?

The probability that you roll a two on a six-sided die is 1 6 16 . if you roll the die 60 times, how many twos can you expect to roll

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem.
