Arc length is equal to its corresponding central angle.

That means that the arc measures 120° too.

Answer:

≈ 4.2 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{120}{360} ( r is the radius )

    = 2π × 2 × \frac{1}{3}

   = 4π ÷ 3

   ≈ 4.2 cm ( to 1 dec. place )

Help! This is so confusing please
Rus_ich [418]

Given equation is f(x)=6^x

Now it says to find f(2)

that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)

f(2)=6^2

f(2)=6*6

f(2)=36

Hence final answer is f(2)=36

If theta is an acute​ angle, solve the equation tangent theta equals four fifths
rusak2 [61]

Answer:

\theta=38.7\degree

Step-by-step explanation:

We want to solve \tan \theta=\frac{4}{5} given that \theta is acute.

We take tangent inverse of both sides to get:

\theta=\tan^{-1}(\frac{4}{5})

Now set your calculator to degree mode and evaluate \tan^{-1}(\frac{4}{5}) to obtain:

\theta=38.6598\degree

To one decimal place, we have;

\theta=38.7\degree
