Answer:

20xπ units

Step-by-step explanation:

Use the formula for the length of an arc.

θ/360 × 2πr

The length of the arc and the central angle is already given.

18/360 × 2πr = xπ

Solve for r.

r = (xπ)/(18/360)/(2π)

r = 10x

The radius is 10x.

The circumference is 2πr.

2π(10x)

20xπ

The circumference of the circle is 20xπ units.

14-2(x+8)=5x-(3x-34)
Scilla [17]

Answer:30=-34


Step-by-step explanation:

First you distribute so 2×X is 2X

2×8 is 16 then you do the other side but you put a one in front of the- so it goes 1 times 3x is 3x and you turn the minus into a plus sign and turn the positive 34 into a negative 34 so -34× 1 is -34 then write that out to look like 14-2X+16= 5X -3X + -34 then you add or subtract the commons which is 14+16= 30 and 5X-3X=2X so now your equation is 30-2x=2X+(-34) then you want to get your X on the same side so you subtract 2X from the right side and the left side then your left 30=-34

Devy likes to learn! Could someone please tell me how to answer this question?
Ronch [10]

Answer:

B

Step-by-step explanation:

Recall that if two functions, <em>f</em> and <em>g</em>, are inverses, then by definition:

\displaystyle f(g(x)) = g(f(x)) = x

Hence, the graph of f(g(x)) should be simply <em>y</em> = <em>x</em>.

Therefore, our answer is B, as both coordinates are equivalent for all three points.
