The interval made of of the third and the minor seventh makes a tritone.
The Hendrix chord typically refers to a Dominant 7th sharp 9 (or 7#9) chord which is simply an extension of a Dominant 7th chord (R,3,5,b7) with an added #9
There are several types of seventh chords, but the most common type of chord is the Dominant 7th(or V7)chord. A Dominant 7th chord is the strongest way to approach the Tonic (I) chord.The Dominant 7th chord with a root of F is diatonic (naturally occurring) to the Bb major scale to reach the Bb major (I) chord. It is also used in the Bb minor scale to reach the Bb minor (i) chord.The F7 chord is also (less commonly) used in the key of Eb major to reach the Bb major (V) chord. The Bb7 is then used to reach the Ebmajor(I) chord.
It starts on the tonic and just has the added B flat, making it the dominant 7th chord.
Assuming you are referring to a chord symbol, like G9 for example, it usually refers to a dominant 7th chord with the ninth degree of the scale added as a color tone. For example, a G9 chord contains the notes G-B-D-F-A, the first, third, fifth, flatted seventh, and ninth notes of the G scale. (The flat 7th, F natural rather than F#, is what makes it a dominant 7th chord.) You also can build a ninth chord using the diatonic 7th step of the major scale, but that kind of chord is called a major 9th rather than a 9th. In G, the major 9th chord (often notated Gmaj9), would be spelled G-B-D-F#-A.
If that's a minor V moving to a IV chord, then no, it's not allowed. A minor V doesn't fit in anywhere in a major key, nor is V permitted to move directly to IV. To have a lowered 7th scale degree in the 2nd chord, leading to IV, try a V7/IV. It's a I chord with a minor 7th in it, working as a secondary dominant.
Tritone substitution in jazz harmony involves replacing a dominant 7th chord with another dominant 7th chord that is a tritone (or three whole steps) away. For example, in the key of C major, instead of playing a G7 chord, you can substitute it with a Db7 chord. This substitution creates tension and adds color to the harmony.
A tritone substitution chart is a tool used in jazz music to replace a dominant 7th chord with another chord that is a tritone (or three whole steps) away. This substitution can create interesting harmonic movement and add color to jazz compositions. It can be used to create tension and resolution in a jazz harmony, adding depth and complexity to the music.
The symbol for a dominant 7th chord is typically written as just the root note of the chord followed by a "7" (e.g., G7 for a G dominant 7th chord).
The difference between a dominant 7th chord and a major 7th chord is the type of 7th interval used. In a dominant 7th chord, the 7th interval is a minor 7th above the root note, while in a major 7th chord, the 7th interval is a major 7th above the root note. This difference gives each chord a distinct sound and function in music.
To create a dominant 7th chord, start with a major chord and add a minor 7th interval on top. This interval is a note that is one whole step lower than the root note of the chord. This combination of notes creates a dominant 7th chord, which has a strong and resolved sound in music.
To write a dominant 7th chord, start with the root note of the chord, then add the major third, perfect fifth, and minor seventh above that root note. The formula for a dominant 7th chord is 1-3-5-b7.

There is actually no such thing as a "dominant scale", however you can use the notes of a dominant 7th chord as a scale and that can begin on any note, the dominant 7th chord in C major is G7 and G7 uses all white keys (G, B, D and F), the structure of a dominant 7th chord is the major triad plus the flatted 7th.
The main difference between a dominant 7th chord and a major 7th chord is the interval between the root and the 7th note. In a dominant 7th chord, this interval is a minor 7th, while in a major 7th chord, it is a major 7th. The use of each chord type impacts the overall harmonic structure of a piece of music in different ways. Dominant 7th chords create tension and are often used to lead to a resolution, adding a sense of movement and instability. Major 7th chords, on the other hand, create a more lush and dreamy sound, adding a sense of sophistication and stability to the harmonic structure.
The main difference between a major 7th chord and a dominant 7th chord is the interval between the root note and the 7th note. In a major 7th chord, the 7th note is a half step below the root, creating a smooth and consonant sound. In a dominant 7th chord, the 7th note is a whole step below the root, creating a more tense and dissonant sound. Major 7th chords are often used in jazz and bossa nova music for their dreamy and sophisticated quality, while dominant 7th chords are commonly used in blues and funk music for their bluesy and unresolved sound.
The basic chords in a major guitar are the major chord, the minor chord, and the dominant 7th chord.
