An airplane starts at 0 feet. It rose 21,000 feet at takeoff. it then descended 4,329 feet because of clouds. An oncoming plane was approaching, so it rose 6,333 feet. After the oncoming plane passed, it descended 8,453 feet, at what altitude was the plane flying?
answer
1). Airplane is flying at 14551 feet.
2). Height of the mountain is 4299 feet.
--------------------------------------------------------------------------------------------------------------
1). An airplane starts at the level = 0 feet
It rose to the altitude = 21000 feet
It descends by the height due to clouds = 4329 feet
So the height of the airplane = 21000 - 4329
= 16671 feet
After giving pass to a plane it ascends by the height = 6333 feet
Now the height of the airplane = 16671 + 6333
= 23004 feet
Then the airplane descends again to give the pass to a airplane again.
Altitude after descending by 8453 feet = 23004 - 8453 = 14551 feet
Airplane is flying at 14551 feet.
2). Distance between the top of the mountain to the floor of the valley = 4392 feet
Valley is 93 feet below the sea level.
Therefore, the height of the mountain will be = 4392 - 93
= 4299 feet

If f(x + 1) = 3x + 2, the function f could be
defined by which of the following?
A) f(x) = 3x - 2
B) f(x) = 3x - 1
C) f(x) = 3x +1
D) f(x) = 3x + 5
Answer:
the answer is f(x) = 3x+5
Explanation:
f(x-1) = 3x + 2
Let, x-1 = a
or, x = a + 1
or, f[a+1-1] = 3(a+1) +2
or, f(a) = 3a + 5
or, f(x) = 3x + 5
If f(x + 1) = 3x + 2, the function f could be f(x) = 3x + 5. Hence option D is correct.
What is function?Function is defined as a statement, rule, or regulation that establishes the connection between two variables. An association of inputs and outputs known as a function occurs when each input has a particular connection to one or more outputs. There is a range, codomain, and domain for every function. A function is typically referred to as f(x), where x is the input. If you enter anything for x, you only get one output for y. The fact that x is the input value leads us to say that y is a function of x.
If x-1 = a,
x = a + 1,
f[a+1-1] = 3(a+1) + 2,
f(a) = 3a + 5,
or f(x) = 3x + 5,
Then f(x-1) = 3x + 2
Thus, if f(x + 1) = 3x + 2, the function f could be f(x) = 3x + 5. Hence option D is correct.

2. State the meanings of the terms (a) rolling friction (b) fluid friction
3. State the likely cause of friction.
Answer:
2) Static friction is a force that keeps an object at rest .The term sliding friction refers to the resistance created by two objects sliding against each other . This can also be called kinetic friction . Sliding friction is intended to stop an object from moving
3) Friction is caused due to irregularities on the surfaces of objects in contact.If we carefully observe the surface of objects through magnifying lens we will see that there are tiny hills and grooves . When two surfaces come in contact with each other these hills and grooves interlock with one another and thus oppose motion .
Hope this helps :)
Answer:
Rolling friction occurs when a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings. The main source of friction in rolling appears to be dissipation of energy involved in deformation of the objects. If a hard ball is rolling…Rolling friction and sliding friction are caused by the rubbing of the surfaces together. The surface of the floor is rubbing the surface of the moving body. This rubbing results to heat produce during the process and the motion of the body is impeded.

In a 300-word essay, describe the main differences between sacred music and secular music. Discuss the purposes of both types of music and explain how people used music to achieve those purposes. Use the internet and search engines to find recordings of O Ignee Spiritus by Hildegard of Bingen (sacred music) and Ecco la Primavera by Francesco Landini (secular music). How do these musical pieces achieve their purposes?
Answer:
The two main categories of music in the Middle Age and the Renaissance were sacred and secular music. The main differences between sacred and secular music were as follows.
Sacred music is “music composed to praise the holy or divine.” This form of music stands apart from the ordinary affairs of human beings and it conveys feelings related to divinity. Most forms of sacred music consisted of setting biblical verses to music to pay homage to God. Sacred comes from the Latin “sacrare”, which means “to set apart.” Thus, sacred music is set apart or consecrated for use within the liturgy, and it remained strictly under the control of the church.
The Middle Ages witnessed the dominance of the Roman Catholic Church over the minds of people, and this dominance was expressed in the music from this age as well. Boys learned music in schools affiliated with the churches, and monks and priests composed music for liturgical purpose. Women and girls were not permitted to sing in churches. However, nuns learned to sing and composed music for choirs.
Sacred music is not an ordinary form of music. It exists for the sole purpose of glorifying God and encouraging people to think divine thoughts. Gregorian chants were the first form of sacred music, and even later forms of sacred music rarely used musical accompaniments.
Secular music differs from sacred music because it deals with themes unrelated to spirituality, making it the exact opposite of sacred music. It pertains to the living rather than to the divine. Secular implies a shift away from the religious; therefore, this music represented a shift in focus from religious to non-religious composition.
French nobles called troubadours composed secular music and sang the first secular songs (mainly dance songs). Secular music themes eventually ranged from simple ballads to love songs, political songs, war songs, laments, and dance songs. The songs eulogized virtues such as chivalry, valor, honor, and love. Secular music used musical accompaniment and had a specific meter and beats set to the music. Composers during Renaissance experimented with musical forms, breaking with the monotony of sacred music and moving to freer and more expressive forms of music. One of the most important composers of that time was Guillaume de Mauchaut, who wrote both sacred and secular music.
Explanation:
Answer:
Secular music is different form sacred music becasue its purpose is different from Sacred music. Spirituality is very irrelevent when it comes to Secular music. In fact Secular music involves more about living than about the clergymen.
The whole point of Sacred music is to stimulate religous thoughts into ones mind.

The surface area, S, of a cylinder with a radius of 5 is defined by [tex]S = 2\pi(5^{2}) + 2\pi(5)h[/tex], where h is the height of the cylinder. If the equation is rewritten in the form [tex]h = \frac{S}{x}-y[/tex], where x and y are constants, what is the value of y ? (Surface Area [tex]= 2\pi rh+2\pi r^{2}[/tex])
-
-
The answer is y = 5, but I can't figure out how, please help.
Answer:
y = 5
Explanation:
S = 2π r² + 2π r h
let r = 5
let h = height of the cylinder
since the equation is re-written in the form h = [tex]\frac{S}{x} -y[/tex]
where x and y are constants.
what is the value of y?
S = (2π r²) + (2π r h) ------ plug in r = 5
S = (2π * 5²) + (2π * 5 * h)
S = (2π * 50) + (10π h)
S = 50π + 10π h
S - 50π = 10π h
S - 50π
h = -------------
10π
S 50π
h = ------ - ---------
10π 10π
S
h = ------ - 5
10π
therefore, the value of y = 5
remember the re-written equation h = [tex]\frac{S}{x} -y[/tex]
and x and y are constants.
x = 10π as constant
y = 5 as constant
hope it clears your mind.
[tex]S=2\pi (5^{2} )+2\pi (5)h\\h=\frac{S}{x} -y\\\\\S=2\pi (5^{2} )+2\pi (5)h\\S=2\pi (25)+10\pi h\\S= 50\pi +10\pi h\\10\pi h= S-50\pi \\h=\frac{S-50\pi }{10\pi } \\h=\frac{S}{10\pi} - \frac{50\pi }{10\pi } \\h=\frac{S}{x}-y = \frac{S}{10\pi} - 5\\y = 5[/tex]

In the xy-plane, the point (p,r) lies on the line with equation y=x+b, where b is constant. The point with coordinates (2p, 5r) lies on the line with equation y=2x+b. If p is not 0 what is the value of p/r
Answer:
4/3
Explanation:
For xy-plane coordinates, points are written as (x, y).
This question gives us two points and two line equations to solve this. Let's start with the first one.
Since p is the x value of the point and r is the y value of the point, we can place these values in our equation y = x + b as follows:
r = p + b
Now we do the same with our second point and line equation. We will substitute 2p for x and 5r for y in the equation y = 2x + b. So we get this:
5r = 2(2p) + b
5r = 4p + b
Since we have this two equations with the same two variables, now we can solve them using the elimination method.
In this case I eliminated b as it is constant in both equations. To do this I subtract the equations in order to cancel the b variable.
5r = 4p + b
r = p + b
_______ -
5r - r = 4p + b - p - b
4r = 3p
4/3 = p/r

Which separation technique will be used by a lady for the separation of dirt from clothes in washing machine?
Answer:
A washing machine works with centrifugation.
Explanation:
Centrifugation is a process that implements a rotating force for the separation of liquids and solids.
The centrifugal force in a washing machine is provided by a drum that is attached to a rotating shaft. This centrifugal force allows the water and soap to combine to permeate the clothes, and the rotational force causes the soapy water to clean the dirt.
In addition to this, the centrifugal process removes most of the water from the garments, favoring drying.
