Answer:

A voice type is a singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points, such as breaks and lifts within the voice.The purpose of the key signature is to minimize the number of such accidentals required to notate the music. The sequence of sharps or flats in key signatures is generally rigid in modern music notation. ... In a score containing more than one instrument, all the instruments are usually written with the same key signature.Bass, Baritone, Tenor, Alto, Mezzo-Soprano, and Soprano. If you've been part of a choir before, you're probably pretty familiar with these ranges.Image result for How do sharps or flats work on a scale?

A sharp symbol on a line or space in the key signature raises the notes on that line or space one semitone above the natural, and a flat lowers such notes one semitone. ... Each major and minor key has an associated key signature that sharpens or flattens the notes which are used in its scales

This should be it I think

Simplify 27 to the negative 2 thirds power. 9 1 over 9 negative 1 over 9 −9
zimovet [89]

Answer:

The answer is 1/9 ⇒ the second answer

Step-by-step explanation:

* In the exponential functions we have some rules

(1) b^(-m) = 1/(b^m)  (for all nonzero real numbers b)

- If we have negative power we reciprocal the base

 to get positive power

(2) (b^m)^n = b^(mn)

- If we have power over power we multiply them

* In our problem: (27)^{-\frac{2}{3}}

- At first change 27 to b^n

∵ 27 = 3 × 3 × 3 = 3³

∴ 27^{-\frac{2}{3}}=(3^{3})^{-\frac{2}{3}}

* Lets use rule (2)

∴ 27^{-\frac{2}{3}}=3^{-2} ⇒ 3 × -2/3 = -2

* Use rule (1)

∴ 3^{-2}=\frac{1}{3^{2}}=\frac{1}{9} ⇒ reciprocal the fraction to change the sig of the power

* The answer is 1/9
