The limit of the function tan 6x/sin 2x as x approaches zero is determined by first substituting x by zero. This is equal to zero over zero which is indeterminate. Using L'hopital's rule, we derive each term in the numerator and denominator separately. This is equal to 6 sec^2 x / 2 cos 2x. when substituted with zero again, the limit is 1/2.
If we set both equations equal to each other, we have 7/x = 4/5, giving us the answer x = 8 3/4, or x = 8.75

Answer: B) y = (1/28)x^2</h3>
Explanation:
p = focal distance = 7
the focal distance is from the vertex to the focus
The parabola opens upward (since the vertex is below the focus) so 'a' is positive and a = 1/(4p) = 1/(4*7) = 1/28
The vertex is (h,k) = (0,0)
Put this all together into the formula below and simplify
y = a(x-h)^2 + k
y = (1/28)(x - 0)^2 + 0
y = (1/28)x^2
