Answer:
The tip of her shadow is moving at the speed of 9.66 ft/sec
Explanation:
The height of the street light = 19 feet
The height of the woman = 5.25 feet
Distance between the woman and the base of the pole, x = 35 ft
The speed of the woman towards the pole, dx/dt = 7ft/sec
The distance from the base of the streetlight to the tip of the woman's shadow = y
The distance from the woman to the tip of her shadow = y - x
The diagram illustrating this description is shown below
Using similar triangle:

Find the derivative of both sides with respect to time, t

The tip of her shadow is moving at the speed of 9.66 ft/sec
Answer: I believe it’s location D. Or whichever is the location of slow crystallization.
Explanation: Slow crystallization of magma forms granite. Hope this helps. :)
The speed for a curve of a given radius is proportional to the square root of the coefficient of static friction. The allowed speed in the second curve is about
(20 m/s)√(0.7/1.1) ≈ 15.95 m/s
Explanation:
The given data is as follows.
Mass of evaporating dish = 3.375 g
Total mass = Mass of solid sample + evaporating dish
That is, Mass of solid sample + evaporating dish = 26.719 g
Therefore, we will calculate the mass of solid sample as follows.
Mass of solid sample = (Mass of solid sample + evaporating dish) - mass of evaporating dish
= 26.719 g – 3.375 g
= 23.344 g
Thus, we can conclude that mass of his solid sample must be 23.344 g.
