1148 miles all you had to do was add 1748+1748=3496 than 1174+1174=2348 and than you had to subtract the 2 numbers and get 1148. So your answer is 1148 miles.
Answer: ![\frac{8}{3}\ ft/s](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D%5C%20ft%2Fs)
Step-by-step explanation:
Given
length of shadow =22 ft
height of woman =5.5 ft
speed of woman ![\frac{dy}{dt}=8\ ft/s](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdt%7D%3D8%5C%20ft%2Fs)
from the figure, we can write
![\frac{22}{x+y}=\frac{5.5}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7Bx%2By%7D%3D%5Cfrac%7B5.5%7D%7Bx%7D)
at given instant
y=20 ft
so, using similar triangle properties
![\frac{22}{x+20}=\frac{5.5}{x}\\22x=5.5x+110\\16.5x=110\\x=6.67\ ft](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7Bx%2B20%7D%3D%5Cfrac%7B5.5%7D%7Bx%7D%5C%5C22x%3D5.5x%2B110%5C%5C16.5x%3D110%5C%5Cx%3D6.67%5C%20ft)
Again we can write
![\dfrac{22}{x+y}=\dfrac{5.5}{x}\\22x=5.5x+5.5y\\16.5x=5.5y\\3x=y\\\text{differentiate w.r.t time} \\3\frac{dx}{dt}=\frac{dy}{dt}\\\frac{dx}{dt}=\frac{1}{3}\times 8=\frac{8}{3}\ ft/s\ \text{away from the woman}](https://tex.z-dn.net/?f=%5Cdfrac%7B22%7D%7Bx%2By%7D%3D%5Cdfrac%7B5.5%7D%7Bx%7D%5C%5C22x%3D5.5x%2B5.5y%5C%5C16.5x%3D5.5y%5C%5C3x%3Dy%5C%5C%5Ctext%7Bdifferentiate%20w.r.t%20time%7D%20%5C%5C3%5Cfrac%7Bdx%7D%7Bdt%7D%3D%5Cfrac%7Bdy%7D%7Bdt%7D%5C%5C%5Cfrac%7Bdx%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes%208%3D%5Cfrac%7B8%7D%7B3%7D%5C%20ft%2Fs%5C%20%5Ctext%7Baway%20from%20the%20woman%7D)
Answer:
Y=9x-21
Step-by-step explanation:
The solution to the problem is as follows:
cot θ = 1 / tanθ
<span>cot θ tanθ = tanθ / tanθ = 1
