Let's see what we're working on here 

\frac{1}{2}  - 2(m) =?
            ? = 0
Simplify this → \frac{1}{2}

\frac{1}2y} - 2(m) = ?

\frac{2(m)(2)}{2}

\frac{1 - 4(m)}{2} = ?

\frac{1 - 4(m)}{2} = 2

-4(m) + 1 = 0
 Subtract ( - )the number 1 from each of your sides on this part

4(m) = 1 
Multiply( ×) the number -1 to your sides for this part of the equation 

Therefore, the value of m is \frac{1}{4}
m =  \frac{1}{4}

a person standing near the top of the Eiffel tower(approximately 300.6 meters) notices a car wreck some distance from the tower.
yarga [219]

Answer:

481.06

Step-by-step explanation:

Let's visualise this case in a right angled triangle.

Height = 300.6 m

Angle of depression = Angle of elevation = 32°

So,

\sin(32)  =  \frac{300.6}{hypotenuse}

=  > 0.5299192642 =  \frac{300.6}{hypotenuse}

=  > hypotenuse =  \frac{300.6} {0.5299192642 }

= 567.2562224244 m

Hypotenuse = Line of sight = 567.25 m

Also,

\cos(32)  =  \frac{base}{567.2562224244}

=  > 0.8480480962 =  \frac{base}{567.2562224244}

=  > base = 0.8480480962 \times 567.2562224244 = 481.0605594599

Hence Base = Distance between the spot of accident & the base of the tower = 481.06 m
