Answer:
Rate at which the shadow is moving = -5 ft/s.
Step-by-step explanation:
I can do the second part for you:
If the distance of the woman from the wall is Xp , the length of the shadow is Xs and the distance from the tip of the shadow to the wall is X we have the relation:
X = Xp + Xs.
We need to find X' (the rate that the tip of the shadow is moving). at Xp = 16 and X'p = -4 ft/s.
We need a relation between X and Xp so we have to eliminate Xs.
By similar triangles 5.5 / 27.5 = Xs / x
1/5 = Xs/x
Xs = x /5 so substituting in the above relation:
X = Xp + X/5
4X/5 = Xp
X = 5Xp / 4
Taking derivatives:
X' = 5X'p / 4
Now X'p is given as - 4 so
X' = -20/4 = -5 ft/s.
Answer:
- 55

Answer:
4/3
Step-by-step explanation:
To find the slope, we can use the slope formula
m= (y2-y1)/(x2-x1)
= ( -1 - -13)/( 3 - -6)
= (-1+13)/( 3+6)
= 12/9
= 4/3
