The formula for wind chill C (in degrees Fahrenheit) is given by C = 35.74 + 0.6215T - 35.75v^0.16 + 0.4275Tv^0.16 where v is th

e wind speed in miles per hour and T is the temperature in degrees Fahrenheit. The wind speed is 23 ± 3 miles per hour and the temperature is 8° ± 1°. Use dC to estimate the maximum possible propagated error and relative error in calculating the wind chill.

Answer:

dC = 2.44

Relative error = 19%

Step-by-step explanation:

C = 35.74 + 0.6215*T - 35.75*v^(0.16) + 0.4275*T*v^(0.16)

Δv = 3 ; ΔT = 1 , v = 23, T = 8

Use differential Calculus

dC = Cv.dv + Ct.dt

Cv = dC/dv = -5.72*v^(-0.84) + 0.0684*T*v^(-0.84)\\Ct = dC/dT = 0.6215 + 0.4275*v^(0.16)\\dC = modulus (Cv.dv) + modulus (CT.dT)\\dC = (-5.72*v^(-0.84) + 0.0684*T*v^(-0.84))* 3 + (0.6215 + 0.4275*v^(0.16))*1\\dC = 2.44

Relative Error

dC / C @(T = 8, v=23)  * 100 = 19 %

A slug takes 4.25 minutes to travel 11.2 centimeters. What is the speed of the slug in meters per second?
MAXImum [283]

Answer:

4.39*10^{-4}\ m/sec

Step-by-step explanation:

Remember that

1\ m=100\ cm

1\ min=60\ sec

The speed is equal to divide the distance by the time

Convert the units

4.25\ min=4.25(60)=255\ sec

11.2\ cm=11.2/100=0.112\ m

so

0.112/255=0.000439\ m/sec

4.39*10^{-4}\ m/sec

The diagram represents a triangle that is reduced by a scale factor of 0.4.
NARA [144]

Answer:the answer would be 8.

Step-by-step explanation:

If you look at the reduced triangle, the height is 2. Therefore you would have to multiply by 4 instead of 0.4 even if the scale factor is 0.4. The reason is, you are enlarging the triangle to find the bigger triangle. If you did 0.4 times 2 you would get 0.8. But that wouldn’t make any sense if you said that that was the height of the ENLARGED triangle.
