The temperature adjusted for wind-chill is a temperature which tells you how cold it feels, as a result of the combination of wind and temperature.

temperature (f)
35 30 25 20 15 10 5 0
5 31 25 19 13 7 -1 -5 -11
10 27 21 15 9 31 -41 -10 -16 wind speed (mph)
15 25 19 13 6 0 -7 -13 -19
20 24 17 11 4 -2 -9 -15 -22
25 23 16 9 3 -4 -11 -17 -24

(a) if the temperature is 0°f and the wind speed is 10 mph, how cold does it feel?
(b) if the temperature is 35°f, what wind speed makes it feel like 25°f?
(c) if the wind is blowing at 10 mph, approximately what temperature feels like 0°f?

a. -16°F

b. 15mph

c. a=12.5F

Step-by-step explanation:

Wind speed           temperature

                                35 30 25 20 15 10 5 0

5                               31 25 19 13 7 -1 -5 -11

10                             27 21   15 9 3 -4 -10 -16

15                             25 19 13 6 0 -7 -13 -19

20                            24 17 11 4 -2 -9 -15 -22

25                            23 16 9 3 -4 -11 -17 -24

going by the table above we interpolate from left to right, to get the corresponding value. where mph meets with the tem[erature in the column is what the temperature feels like

(a) If the temperature is 0°F and the wind speed is 10 mph, how cold does it feel?

ans -16°F

b. If the temperature is 35°F, what wind speed makes it feel like 25°F?

answer 15mph

c(c) If the wind is blowing at 10 mph, approximately what temperature feels like 0°F?

Form difference quotient across the row starting at position (10, 30):

is 6/5

6/5=(0-3)/a-15

a=12.5F

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

36
