Answer:
Step-by-step explanation:
quadrants (that are labeled from first to fourth and are denoted by roman numerals). ▫. Students identify ... Some important aspects for students to remember include the following: ▫. The -axis ... Graph at least five points on the -axis, and label their coordinates. Points will vary. ... compare the standard symbols
It means nothing. Example: <span>3 – 3 means start at 3 and go down 3.
</span>
<span />
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.
Answer:
it opens down meaning it has a maximum instead of a minimum. the graph has a horizontal shift of 3 spaces to the right
