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 :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
s = 10│x - 4│+ 50
s represents the sound level in decibels and x represents the number of measures of music played
To find x at s = 80
The equation becomes /
80 = 10│x - 4│+ 50
Subtract 50 from both sides of the equation
80 - 50 = 10 |x - 4| + 50 - 50
30 = 10 | x - 4 |
Divide both sides by 10
30/10 = 10|x - 4| / 10
3 = |x - 4|
|x - 4| is an absolute value expression
±3 = |x - 4|
x = 3 + 4 = 7
x = - 3 + 4 = 1

ball is thrown 40 meters above ground. the height of the ball from the ground level after t seconds is defined by using the function h(t)=40t-5t^2. how long will the ball take to hit the ground
Answer:
The ball will take 8.90 seconds to hit the ground.
Step-by-step explanation:
The height of a ball after t seconds is given by:
[tex]h(t)=40t-5t^2[/tex]
Determine how long will the ball take to hit ground level. Since the gound is 40 meters below the throwing point:
[tex]40t-5t^2=-40[/tex]
Rearranging:
[tex]5t^2-40t-40=0[/tex]
Simplifying by 5:
[tex]t^2-8t-8=0[/tex]
Solving the quadratic equation with the formula:
[tex]\displaystyle t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
With a=1, b=-8, c=-8
[tex]\displaystyle t=\frac{8\pm \sqrt{64+32}}{2}[/tex]
[tex]\displaystyle t=\frac{8\pm \sqrt{96}}{2}[/tex]
There are two solutions:
t=8.90 sec, t=-0.90 sec
Due to the nature of the problem, t cannot be negative, thus:
The ball will take 8.90 seconds to hit the ground.

Two friends rent an apartment together.
They agree that one person will
рау 1.5
times what the other person pays. If the rent
is $850, how much will each friend pay?
Answer:
Friend A pays $340 and friend B pays $510
Step-by-step explanation:
Let's call
x: payment of friend A
1.5x: payment of friend B
The sum of both payments must total $850, thus:
x + 1.5x = 850
Simplifying:
2.5x=850
x = 340
Now for friend B:
1.5x=1.5*340=510
Friend A pays $340 and friend B pays $510
This is my question

What is the sine of an angle in a right angle triangle?The sine of an angle is the ratio of the height and the hypotenuse of the triangle.
Given, ∠C = 30°
AB = 16
Therefore, sin ∠C = (AB/AC)
Therefore, sin (30°) = 16/AC
⇒ (1/2) = 16/AC
⇒ AC = 2 × 16
⇒ AC = 32

Find three consecutive odd integers such that the sum of the smallest number and middle number is 27 less than 3 times the largest number
Answer:
x+(x+2) = 3(x+4) -27
Step-by-step explanation:
Let's look at all the parts.
Consecutive odd integers... that means that if x is the first one, then x+2 will be the next largest one, and x+4 will be the largest one. So if x is 5, x+2 is 7, and x+4 is 9.

Is the following number irrational?
-8.7
Answer:
No.
Step-by-step explanation:
Rational numbers are any of the following:
Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...Irrational numbers are thus defined as:
Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.
