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

Can someone please help me find the domain, range, intercepts, and asymptotes pf this function?

marishachu [46]

1) given function

y = - 2 ^ ( -x + 2) + 1

2) domain: domain is the set of the x-values for which the function is defined.

The exponential function is defined for all the real numbers, so the domain of the given function is all the real numbers.

3) x-intercept => y = 0

=> y = - 2 ^ ( -x + 2) + 1 = 0 => 2^ ( -x + 2) = 1

=> - x + 2 = 0 => x = 2

The x-intercept is x = 0

4) y-intercept => x = 0

=> y = - 2 ^ ( -x + 2) + 1= - 2 ^ ( 0 + 2) 1 = - (2)^(2) + 1 =- 4 + 1 = - 3

=> The y-intercept is - 3

5) limit when x -> negative infinite

Lim f(x) when x -> ∞ = - ∞

6) limit when x -> infinite

Lim f(x) when x - > infinite = 1

=> asymptote = y = 1

7) range is the set of values of the fucntion: y

Given that the function is strictly decreasing from -∞ to ∞, the range is from - ∞ to less than 1

Range (-∞,1)

Solomon has read 1/3 of his book. He finishes the book by reading the same amount each night for 5 nights.

Nadusha1986 [10]

Answer:

A - Solomon read $\frac{2}{15}$ of the book each night.

B - The total number of pages in the book are 105.

Step-by-step explanation:

We are given that,

Solomon has read $\frac{1}{3}$ of a book.

So, $1-\frac{1}{3}=\frac{2}{3}$ of the book is left to be read.

Ques A: We have that,

In 5 nights, Solomon read $\frac{2}{3}$ of the book.

So, on 1 night, he will read, $\frac{2}{3}\times \frac{1}{5}$ = $\frac{2}{15}$ of the book.

Thus, Solomon read $\frac{2}{15}$ of the book each night.

Ques B: Let the total pages of the book = x.

Solomon reads 14 pages in 1 night. So, he reads, 14 × 5 = 70 pages in 5 nights.

Since, these 70 pages represent the $\frac{2}{3}$ of the book, he read in 5 nights.

So, $\frac{2}{3}$ of the total pages = 70

i.e. $\frac{2}{3}x=70$

i.e. x= 105

Hence, the total number of pages in the book are 105.

Jon and Jim painted a fence.Jon painted 1-4 of the fence and Jim painted 5-12 of the fence.How much of the fence did they paint

pantera1 [17]

Find the number of fence did Jon and Jim painted
Jon painted 1 – 4
Jim painted 5 – 12
1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10 - 11 – 12
- Jon - Jim
They painted a total of 12 fences. Because Jon started on paint in the first up to 4th fence and Jim started to paint on the 5th going to the 12th fence. Thus, the total of the fence they painted is still 12.
