A decibel is a logarithmic unit that can be used to measure the intensity of a sound. The function y = 10logx gives the intensit

Anna007 [38]

Answer:

The sound intensity of a whisper is 333.3 times the reference intensity

Step-by-step explanation:

Given : The function $y = 10logx$ gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity.

A whisper has a sound intensity of 30 decibels.

To find : Use your graph to help you complete the following statement. The sound intensity of a whisper is times the reference intensity.

Solution :

Graph is attached which shows their intersection at (1000,30).

We can also verify by substituting value.

We have given that a whisper has a sound intensity of 30 decibels.

Therefore, y=30 , Let log base 10

$y = 10logx$

$30 = 10logx$

$\frac{30}{10} =logx$

$3=logx$

Logarithmic property $log_{x}b=a \Rightarrow b=x^a$

$x=10^3$

$x=1000$

The ratio of the intensity of the sound to a reference intensity is 1000 decibels

The sound intensity of a whisper is times the reference intensity is

$\frac{1000}{3}=333.33$

The sound intensity of a whisper is 333.3 times the reference intensity.

Help quick please. Order the numbers from least to greatest.

Anastasy [175]

Answer:

$-2\frac{1}{4}$

Step-by-step explanation:

Mod of any number represents the absolute value of the number.

Therefore, $|-2\frac{1}{4}|=2\frac{1}{4}$ = 2.25

$-2\frac{1}{4}=-2.25$

$|1\frac{1}{4}|=1.25$

$\frac{3}{4}=0.75$

$|-1\frac{3}{4}|=1\frac{3}{4}=1.75$

$-1\frac{1}{4}=-1.25$

Now we can arrange these numbers in ascending order.

-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25

Therefore, $-2\frac{1}{4}$

Hey there (again)

$x = 2y \\ y = -2 \\ x = 2(-2) \\x= -4 \\ \\ \\ w + xy + 4x^2 = 2\\ w+-4(-2) + 3(-4)^2 = 2 \\ w + 8 + 3(16) = 2 \\ w + 8 + 48 = 2 \\ Subtract56: w + 56 =2 \\ 56 - 56 (Cancel) \\ 2 - 56 = -54 \\ w = -54$

Answer: $B$ the simplification performed in step 2 is invalid or incorrect

Good luck on your assignment and enjoy your day
