Suppose,
x = distance of the man
<span>s = length of the shadow</span>
<span>Using the idea of similar triangles</span>
<span>6/s = 23/(x + s) </span>
<span>Simplifying:</span>
we get,
<span>6(x + s) = 23s </span>
<span>6x + 6s = 23s </span>
<span>6x = 17s </span>
<span>Differentiating with respect to time, </span>
<span>6(dx/dt) = 17(ds/dt) </span>
<span>Manipulating the above equation for ds/dt,</span>
<span>ds/dt = (17/6)(dx/dt) </span>
<span>ds/dt = (17/6)(6) </span>
<span>ds/dt = 17 ft/sec.</span>
Answer:
x = 4
Step-by-step explanation:
3(x + 3) - 5 = 16
First, distribute the 3 on the left side.
3x + 9 - 5 = 16
Now, combine like terms on the left side.
3x + 4 = 16
Subtract 4 from both sides.
3x = 12
Divide both sides by 3.
x = 4
