The windchill index announced during the winter by the weather bureau measures how cold it "feels" for a given temperature t (in degrees Fahrenheit) and wind speed w (in miles per hour). It is calculated by the formula C(t, w) = 35.74 + 0.6215t - 35.75w 0.16 + 0.4275tw0.16 + '.+ If the temperature is 31 degrees and the wind speed is 10 miles per hour, estimate the change in the windchill temperature if the wind speed increases by 4 miles per hour and the temperature drops by 5 degrees. (Round your answer to two decimal places.)

I can not seem to get 1/π. My professor insisted the answer be 1/π. But I've kinda worked out and wanted to see if I'm on the right track. I need help for 1b.

Graph the Ine whose x-tercept is -I and whose y-intercnpt is 1.

Why is s = 2y?

Let g(t) give the total number of gallons of maple syrup sold by a local farmer over the first t days after the start of the year. If it takes approximately 0.2 days after the farmer sells their 45th gallon of maple syrup for them to sell the 46th gallon, fill in the mathematical expression below with the correct input and output values: (9-)' (

The values for P(A₁B) and P(A₂B) were found to be 0.20 and 0.02, respectively. Use these values to calculate P(A₁ | B) to four decimal places. P(A₁ | B) = P(A, B) P(A₁B) + P(A₂ MB) 0.20 0.20+ 0.02 = 0.22 X

The projected population of the United States for the years 2025 through 2055 can be modeled by P = 307.58e0.0052t, where P is the population (in millions) and t is the time (in years), with t = 25 corresponding to 2025.
