Answer:
rise-over-run value for the relationship represented in the graph is 30.
Step-by-step explanation:
Answer:
no u can gain back the a
Step-by-step explanation:
-2 times -2 will give you 4 or (-2 x -2=4)
-8 times -2 will give you 16 or (-8 x -2=16)
16 times -2 will give you -32 or (16 x -2=-32)
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
