The polynomial in descending order would be:

x^12 + 3x^7 + 4x^3-9x.

It all has to do with their degrees (exponents).

I don't know what the answer choices are because you didn't post them, but that is the answer.

I hope this helps.

Find the surface area of the composite solid. Round your answer to the nearest hundredth.
horrorfan [7]

Answer:

The answer is

A. 529.66 ft²

Step-by-step explanation:

The picture of the composite figure is not given,

But find attached the figure.

The composite consists of two solid shapes

1. Cylinder

2. Rectangular prism

To solve for the total surface area of the composite

Let us solve for the total surface area of the cylinder

Given radius r= 4ft

Height h=5ft

A= πr²+2πrh-πr²

N/B we subtracted the second circular surface since it is joined to the rectangular prism

A= 3.142*4²+2(3.142)*4*5-3.142*4²

A= 50.272+125.68-50.272

A=125.68ft²

We proceed to find the area of the rectangular prism

We know that the prism has 6 sides

Hence area

A= 2(11*6)+ 2(8*6)+2(11*8)

A= 132+96+176

A= 404ft²

Hence total surface area is

404+125.68= 529.68ft²

400 passengers go on a coach trip.
Afina-wow [57]

Answer: <u>₹759407.56</u>

Step-by-step explanation: Total No. of passengers = 400

1 Coach = 50 passengers

∴Total No. of coaches= 400/50=8 coaches.

Cost for each passenger= £23

∴Total cost for 400 passengers= 400x£23

= £9200 ( 1£=82.5443 ₹) ∴ Total cost for passengers = <u>₹759407.56</u>

Money spent per mile= 70p

∴Money spent for 200 miles= 200x70p=14000p

(1₹=100p) thus, 14000p=<u>₹140</u>

<u><em>Total profit</em></u>= <em>Money from the passengers- Money spent for fuel</em>

∴<u>₹759407.56- ₹140=  ₹7,59,407.56</u>

<u>Actually I am a 9th grader and I have tried this question, so I am not sure for my answer, But I have tried my level best.</u>

gavmur [86]
This is the concept of geometry, the function given by f(x)=cos^x
can be written as cos y=x
The domain if the function is [-1,1] and the range is given by [0,π] where π=180°
