Answer:

$\boxed{\mathrm{all \: real \: numbers}}$

Step-by-step explanation:

$F(x)=2^x$

The domain of a function is the set of input values that the function can take.

There are no restrictions on the value of x.

The domain of the function is all real numbers.

$- \infty\leq x\leq \infty$

In three hours, Company ABC can make X ball bearings. Company DEF can make X ball bearings in 4 hours. Company GHI can make X ba

amm1812

Answer:

<em>X ball bearings will be made in 1 hour and 20 minutes</em>

Step-by-step explanation:

<u>Proportions </u>

The proportions give us an important tool to easily solve common problems of any type. We know that:

Company ABC can make X ball bearings in 3 hours.

Company DEF can make X ball bearings in 4 hours.

Company GHI can make X ball bearings in 6 hours.

In one hour, each company can make

ABC: X/3 ball bearings

DEF: X/4 ball bearings

GHI: X/6 ball bearings

Working together, they can make

$\displaystyle \frac{X}{3}+\frac{X}{4}+\frac{X}{6}$

ball bearings. Operating

$\displaystyle \frac{4X+3X+2X}{12}=\frac{9X}{12}=\frac{3X}{4}$

If they can make 3/4 of a ball bearing in one hour, then one complete ball bearing will need

$\displaystyle \frac{4}{3}$ hours to complete. It's equivalent to 1 1/3 hours or 1 hour and 20 minutes

X ball bearings will be made in 1 hour and 20 minutes

Which proportion can be used to find the arc length, s, in units?

Alinara [238K]

Answer:

Option B

Step-by-step explanation:

Formula to be used to calculate the length of an arc,

Length of arc = $\frac{\theta}{360}(2\pi r)$

Here, θ = Angle subtended at the center by the arc

r = radius of the circle

By substituting values in the formula,

s = $\frac{150}{360}(2\pi )(42)$

$\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )$

$\frac{s}{84 \pi }=\frac{150}{360}$

Therefore, Option B will be the answer.
