The value of cos 4x from the given identity is 0.999
<h3>Trigonometry identity</h3>
Given the cosine identity
cos8x = 13/36
Determine the value of x
8x = arccos(13/36)
8x = 0.36111
x = 0.36111/8
x = 0.04514
Determine the value of cos4x
cos4x = cos4(0.04514)
cos4(0.04514) = 0.999
Hence the value of cos 4x from the given identity is 0.999

The complete question is
The slope of the line below is 0.5 Write the equation of the line in point-slope form, using the coordinates of the labeled point. <span>It's on a number line which is (3,-3) Do not use parenthesis on the y side.
we know that
</span>Point slope form is
<span>y - y₁ = m(x - x₁) </span>
<span>Where m= slope and (x₁, y₁) is a point on the line
</span><span>Plug in m = 0.5 and point (3, -3)
</span><span>y-(-3)=0.5*(x-3)------> y+3=0.5*(x-3)
the answer is
</span> y+3=0.5*(x-3)<span>
