There is a rule:

One input(x-value) can only have one output(y-value) in order to be a function.

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

The 1st option is not a function because the inputs 9 and 10 have more than one output.

The 2nd option is not a function because the input 3 has more than one output.

The 3rd option is a function because each input only has one output.

The 4th option is not a function because the input 5 has more than one output.

Use the arc length formula and the given information to find r.

jek_recluse [69]

Answer:

Step-by-step explanation:

The thing with the arc length formula, s = rt, is that t is the angle in radians. Ours is in degrees, so we have to change it:

36 × $\frac{\pi }{180}=\frac{\pi }{5}$

So the formula we use to solve for r is:

$12=\frac{\pi }{5}r$

Multiply both sides by 5 over pi to get that

$r=\frac{60}{\pi } cm$

Express 0.7033 as a mixed number

viva [34]

We can make 0.7033 an improper fraction by multiplying it by 10,000 to get:

7033/10,000

Note that this cannot be a mixed number because 10,000, the denominator, is greater than 7033, the numerator.

You may have misspelled or typoed the question, or the question might be wrong, because 0.7033 can't be written as a mixed number.
