At 6:00 PM, a flagpole that is 35 feet tall casts a shadow that is 50 feet long. At the same time, how long will a person's shad
sertanlavr [38]

<u>Answer:</u>

The length of the person’s shadow is 5.7ft

<u>Explanation:</u>

Length of the flagpole =a= 35ft

Length of the shadow of the flagpole= b=50ft

Length of the person=c= 4ft

Suppose the length of the person’s shadow is=d

According to the  rules of trigonometry

\frac{\text { Length of the flagpole }}{\text { Length of the shadow of the flagpole }}=\frac{\text { Length of the person }}{\text { Length of the person's shadow }}

\frac{a}{b}=\frac{c}{d}

\frac{35}{50}=\frac{4}{d}

35d=200

d=\frac{200}{35}

d=5.7ft  

Hence, The length of the person’s shadow is 5.7ft.

How are the functions f(x)=16x and g(x)=16 1/2x related? The output values of g(x) are one-half the output values of f(x) for th
KATRIN_1 [288]
If your functions are
  f(x) = 16·x
  g(x) = 16·(1/2x)
The output values of g(x) are one-half the output values of f(x) for the same value of x.

If your functions are
  f(x) = 16^x
  g(x) = 16^(1/2x)
The output vaules of g(x) are the square root of the output values of f(x) for the same value of x.

bogdanovich [222]
Since the absolute value makes numbers absolute or real numbers you could replace the ? with 8/9 or -8/9 since the negative will go away because of the absolute value sign.
