Question

The wind chill factor represents the equivalent air temperature at a standard wind speed that would produce the same heat loss as the given temperature and wind speed. One formula for computing the equivalent temperature is where v represents the wind speed (in meters per second) and t represents the air temperature . Compute the wind chill for an air temperature of 15°C and a wind speed of 12 meters per second. (Round the answer to one decimal place.)

Answer 10

hint: v = 12

look at the right side of each equation to determine which of the three equations to use

Answer 11

so i would use the second one right ?

Answer 12

right.

plug in v = 12 and t = 15, then you'll have your answer

Answer 13

this is new to me so how would i work that out

Answer 14

your equation is

33 - (10.45+10sqrt(v)-v)(33-t)/22.04

after you substitute 12 for v and 15 for t it becomes

33-(10.45+sqrt(12)-12)(33-15)/22.04

Answer 15

plug all of that into a calculator and then you'll have your answer

Answer 16

ohh lol ok thnx again smh i feel stupid now haha

Answer 17

31.4367591164936669 is my answer

Answer 18

(Round the answer to one decimal place.

Answer 19

so 31.5 or 31.0

Answer 20

not quite

31.4367591164936669 rounds to 31.4 (remember, you keep the digit in the tenths place (4), then look at the next digit to decide where to round. since 3 (the next digit) is below 5, you round down)

Answer 21

one decimal means one digit to the right of the decimal point

Answer 22

ohh ok so v=31.4 right

Answer 23

not quite, v isn't part of the answer anymore, it's just 31.4

Answer 24

ok thnx lol
