(4*10,000)+(8*1,000)+(2*100)+(4*10)+(3*1)

40,000+8,000+200+40+3=48,243

That is one way. You can also do this using exponential form!

Hope that helps

(Please help) Which answer describes the polynomial?

lbvjy [14]

$\bf 3x^3+4x^2-7\quad 
\begin{cases}
3x^3\impliedby &3rd~degree\\
4x^2\impliedby &2nd~degree\\
7\impliedby &0~degree
\end{cases}$

notice, there are three terms, therefore is a trinomial.

the term that has the highest degree, has a degree of 3, therefore the degree of the polynomial as a whole is 3, or a cubic degree.

so, is a cubic trinomial.

Complete the table:

Dafna11 [192]

Answer:

d. 0

Step-by-step explanation:

The table can be interpreted as:

$\theta = 0$

Required

Find $sin(\theta)$

$sin(\theta)$

Substitute: $\theta = 0$

$\sin(\theta) = \sin(0)$

Using a calculator

$\sin(0) = 0$

Hence:

$\sin(\theta) = 0$

The diagram shows a sector of a circle radius 10cm

Yuki888 [10]

Answer:

$\text{Perimeter of sector = 43.6 (Rounded to the nearest tenth.)}$

Step-by-step explanation:

$\text{Perimeter of the sector = Radius + arc length + radius}$

$\text{Radius = 10 cm}$

$\text{Perimeter of the sector = 10 + arc length + 10 }$

$\text{Perimeter of the sector = 20 + arc length }$

$\text{arc length = (sector angle/ 360 ) * perimeter of the circle}$

$\text{Perimeter of a circle }=2\pi r$

$\text{sector angle} = 135$

$\text{arc length} = (135/ 360 ) * 2\pi (10)$

$= (3/8) 20\pi$

$= 15\pi /2$

$\text{Using }\pi =3.14$

$= 15 * 3.14 /2$

$= 23.55$

$\text{Perimeter of the sector = 20 + 23.55}$

$= 43.55$

$= 43.6 cm$

$\text{perimeter of the sector = 43.6 cm }$
