During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibles?
( I need the answers, plus the steps please and thank youuu :)
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equation:
s = 10│x - 4│+ 50
Where s = sound level in decibels
x = number of measures of music played
Step 1:
Subtract 50 from Both sides
s - 50 = 10│x - 4│+ 50 - 50
s - 50 = 10│x - 4│
For s = 80
80 - 50 = 10│x - 4│
30 = 10│x - 4│
Clear the absolute value sign
± 30 = 10x - 40
Hence ;
Lower value :
- 30 + 40 = 10x
10 = 10x
x = 1
Upper value :
+30 + 40 = 10x
70 = 10x
x = 7

Unfortunately, his investment depreciated steadily, losing 15% of its value each year. a. What is the multiplier? b. Write a function using f(t) to describe the situation. c. How much is the stock worth now?
Answers
Answer:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49
Step-by-step explanation:
Given that:
Initial investment made, 8 years ago = $1000
Depreciation value each year = 15%
To find:
a. Multiplier
b. Function [tex]f(t)[/tex] to describe the situation.
c. Worth of stock now.
Solution:
a. Depreciation of 15% means the value becomes (100 - 15) % = 85% or 0.85 of the actual value.
Therefore, the multiplier is 0.85.
b.
Every year the value becomes 0.85 times of the actual value.
If it continues for [tex]t[/tex] years, then the values will be:
[tex]f(t) =1000(0.85)^t[/tex]
c. Let us put [tex]t=8 \ years[/tex] to find the worth of stock now.
[tex]\Rightarrow f(8) =1000(0.85)^8\\\Rightarrow \bold{\$272.49}[/tex]
So, the answers are:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49

Answers
Answer:
a = 60
60°, 60°, 120°, and 120°
Step-by-step explanation:
So we know that the sum of the angle measures of the quadrilateral is 360° and that the four angle measures are a, 2a, a, and 2a. This means that the sum of a, 2a, a, and 2a should equal 360.
a + 2a + a + 2a = 360
Combine like terms.
6a = 360
Divide both sides by 6.
a = 60
So the value of a would be 60.
Now to find the angle measures from least to greatest, we would have to find the values of a, 2a, a, and 2a.
a = 60
2a = 120
a = 60
2a = 120
So the angle measures from least to greatest is 60°, 60°, 120°, and 120°.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
a=60 degrees
Step-by-step explanation:
Total angle measurements=360 so
2a+2a+a+a=360
2(60)+2(60)=240
240+60+60=360
----------------------------
So a=60

Answers
Answer:

I am divisible by 5.
So your ones digit is 0 or 5
I am an even number.
So your ones digit is 0. We fill that in.
_ _ 0
My tens digit is 1.
So we fill that in.
_ 1 0
My tens digit is greater than my ones digit.
Well, of course 1 is greater than 0. We didn't need to be told that.
I have only one odd digit.
Since the 1 is odd, the hundreds digit is even, 2,4, or 8
I am less than 400.
So your hundreds digit is 2. Fill that in and we're done.
2 1 0
My hundreds digit is greater than my tens digit.
Of course 2 is greater than 1, we didn't need to be told that.
I am divisible by 3.
Of course 210 is divisible by 3. We didn't need to be told that.

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x
+1?
Oright 1 unit
o left 1 unit
Oright 2 units
left 2 units
Answers
Answer:
The translation is left 1 unit, up 5 units ⇒ A
Step-by-step explanation:
Let us revise the rules of translation of a function
If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h = and k = f(h)
You will use the vertex form to find the translation
∵ g(x) = x² + 2x + 6
∴ a = 1 and b = 2
→ use the rule of h to find it
∴ h =
∴ h = -1
→ Use it to find k
∵ g(h) = k
∴ k = g(-1)
→ Substitute x by -1 in g to find k
∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6
∴ k = 5
→ Substitute the values of h and k in the vertex form above
∴ g(x) = 1(x - -1)² + 5
∴ g(x) = (x + 1)² + 5
→ By using the 2nd and 3rd rules of translation above
∴ f(x) is translated 1 unit to the left and 5 units up
∴ The translation is left 1 unit, up 5 units

it's A. left 1 unit
