For simplicity, dy/dx means f'(x);
We have y = ( 8 - x^2 ) / 2x;
Then, y = 4/x - x/2;
So, f'(x) = (4/x - x/2)' = (4/x)' - (x/2)' = -4/(x^2) -1/2 because we use <span> d<span>ifferentiation formulas, such as : (f+g)' = f' + g'; (cf)' = cf'; x'=1; (1/x)' = -1/(x^2);
</span></span>Finally, f'(4) = -4/16 -1/2 = -4/16 - 8/16 = -12/16 = -3/4.
The correct answer is E.
40 degrees, because ΔABC is isoceles, so angles B and C are equal.
A scale of 
inch represents 
feet
<em><u>Solution:</u></em>
Given that,
On a scale drawing
45 inches represented = 75 feet
We have to find a scale of inch in feet
Let us first find 1 inch in feet
From given,
45 inches = 75 feet
Therefore,
Now find for inch in feet
Thus a scale of inch represents feet
