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).
1750 2 x 5p x q where p and q are prime numbers Work out the value of p and the value of q?
1750 2 x 5p x q where p and q are prime numbers. 2 * 5^p * q where p = 3 and q = 7
Can a 3 X 4 matrix be multiplied by a 4 X 1 matrix?
Yes. If one matrix is p*q and another is r*s then they can be multiplied if and only if q = r and, in that case, the result is a p*s matrix.
