Astreet light is at the top of a 11 ft tall pole. a woman 6 ft tall walks away from the pole with a speed of 7 ft/sec along a straight path. how fast is the tip of her shadow moving when she is 50 ft from the base of the pole?

The answer is 8.5 Ft/Sec.

The tip of the woman's shadow is moves from the base of the pole when she is 50ft away at the speed of 8.5 Ft/Sec

Step-by-step explanation:

The tip of the woman's shadow is moves from the base of the pole when she is 50ft away at the speed of 8.5 Ft/Sec

The solution and explanation is attached.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
