Answer:

arc ≈ 5.5 units

Step-by-step explanation:

The arc of the circle is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{\frac{\pi }{2} }{2\pi }$ ( r is the radius )

= 2π × 3.5 × $\frac{1}{4}$

= $\frac{7\pi }{4}$

≈ 5.5 ( to the nearest tenth )

So, (n о v о s)(x) is $|\sqrt{2^x}|+2$

Option C is correct.

Step-by-step explanation:

We are given:

$n(x)=2^x, \,\,s(x)=\sqrt{x}, \,\,v(x)=|x|+2$

We need to find (n о v о s)(x)

(n о v о s)(x) is equal to: n(v(s(x)))

First we will find v(s(x))

Plugging s(x) into v

$=|\sqrt{x}|+2$

Now finding n(v(s(x)))

Putting v(s(x)) into n(x)

$=|\sqrt{2^x}|+2$

So, (n о v о s)(x) is $|\sqrt{2^x}|+2$

Option C is correct.

Hank has 4 green marbles for every 9 red marbles. If hank has 39 total marbles, how many green marbles does he have? pls answer

mixer [17]

He has 12 green marbles. 4+9=13 and 39/13=3 so 4x3=12. to check, we can do 9x3=27 as well and add our results. 12+27=39 so we know we are correct.
