Length of distance of arc = 2πr × (∅/360)

∅ = 1/60 × 360 = 6⁰

Length = 2 × 22/7 × 3960(6/60)

Length = 44/7 × 3960 × 1/10

Length = 44/7 × 396

Length = 2489.142 cm

How to find the multiplicity of a zero of a polynomial function?
Monica [59]
<span>The multiplicity of a zero of a polynomial function is how many times a particular number is a zero for a given polynomial.

For example, in the polynomial function f(x)=x(x+4)^2(x-2)^3, the zeros are 0 with a multiplicity of 1, -4 with a multiplicity of 2, and 2 with a multiplicity of 3.

Although this polynomial has only three zeros, we say that it has six zeros (or degree of 6) counting the <span>multiplicities.</span></span>

68 * 27 - 81 + ? = 600
tankabanditka [31]

The missing term is -1155.

Step-by-step explanation:

Given expression is

68 * 27 - 81 + ? = 600

Let the missing term be x

68*27-81+x=600\\1836-81+x=600\\1755+x=600

Subtracting 1755 from both sides

1755-1755+x=600-1755\\x=-1155

Therefore,

The missing term is -1155.

Solve in degrees. 0 &lt; θ &lt; 360<br> 1. tan θ = 3.5134
Temka [501]

Answer:

Therefore,

\theta=74.11\°\ or\ \theta=254.11\°

Step-by-step explanation:

Given:

0° < θ < 360°

tan θ = 3.5134

To Find:

θ in degrees = ?

Solution:

0° < θ < 360° .............Given

Means ' θ ' is between 0° and 360°

\tan \theta=3.5134 .............Given

Therefore,

\theta=\tan^{-1} (3.5134)

Also,

\tan (180+\theta)=\tan \theta

So  ' θ '  will have Two values for tan θ =3.5134

\therefore \theta=74.11\°\ or\ \theta=180+74.11=254.11\°

Therefore,

\theta=74.11\°\ or\ \theta=254.11\°
