Given a data series, sampled at ƒk = 1/T, T being the sampling period of our data, for each frequency bin we can define the following:
- Filter width δƒk
- Q, the "quality factor". This is shown below to be the integer number of cycles processed at a center frequency ƒk. As such, this somewhat defines the time frequency of the constant Q transform.
Q = ƒk / δƒk

What is the vertex of x minus 4 squared equals to 2 y plus 5?
The equation you gave, 2y+5 = (x-4)2 can also be expressed as y = 0.5(x-4)2 - 5. In the form a(x-p)2 + q, the vertex is the point (p, q). Thus, the vertex of 2y + 5 = (x-4)2 is (4, -5).

Given the function p(x) and q(x) (p plus q) (x) p(x) at the x-intersept(s) of q(x)?
Yes.
What binomial is a factor of this trinomial x2 plus 13x plus 4?
x2 + 13x + 4 = (x + 6½ + √38¼)(x + 6½ - √38¼). To find this, we need to find p and q, where p + q = 13, pq = 4. 4 = 42¼ - 38¼ = (6½ + √38¼)(6½ - √38¼); thus, p = (6½ + √38¼), q = (6½ - √38¼).

How do you rewrite each sum as a product of the greatest common factor of the addends and another number?
Suppose that for any pair of numbers x and y, gcf(x, y) = g then x = g*p and y = g*q for some integers p and q. Therefore x + y = g*p + g*q = g*(p+q).

What do you do if the base number is not a fraction but the exponent is a fraction?
Consider have x^(p/q) where the base, x, is a whole number. p and q are also whole numbers (q is not 0) so that the exponent, p/q, is a fraction. Then x^(p/q) = (x^p)^(1/q), that is, the qth root of x^p or equivalently, x^(p/q) = [x^(1/q)]^p, that is, the pth power of the qth root of x. For example, 64^(2/3) = 3rd root of 64^2 = 3rd [cube] root of 4096 = 16 or (cube root of 64)^2 = 4^2 = 16. If p/q is negative, the answer is the reciprocal of the answer obtained with positive p/q.
How do you subtract fractions butterfly method?
For the denominator, multiply the denominators together. For the numerator, subtract the second numerator multiplied by the first denominator from the first numerator multiplied by the second denominator: a/b - p/q = (a x q - b x p)/b x q eg: 6/7 - 3/4 = (6 x 4 - 7 x 3)/7 x 4 = (24 - 21)/28 = 3/28
What is the sign of the y vaue of a point?
That depends on whether it's above the x-axis (Q-1 or Q-2) or below the x-axis (Q-3 or Q-4). So, based on the information in the question, it could go either way.
