Answer:

16.9 m

Step-by-step explanation:

Start with a half a circle. The central angle of a semicircle is 180 deg.

Now subtract 21 deg on each side.

180 - 21 - 21 = 138

The central angle is 138 deg.

The radius is 7 m.

Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.

$s = \dfrac{n}{360^\circ}2 \pi r$

$s = \dfrac{138^\circ}{360^\circ}2(3.14159)(7~m)$

$s = 16.9~m$

You graph the function f(x)=-|×|-12

Firlakuza [10]

Answer:

See attachment

Step-by-step explanation:

We want to graph $f(x)=|x|-12$ on the interval -10 to 10.

Let $g(x)=|x|$ be the parent absolute value function.

We can easily graph $f(x)=|x|-12$ , if we use translation.

When the parent function is shifted downwards by 12 units, we obtain the graph of $f(x)=|x|-12$ .

The parent function is a v-shaped graph with vertex at the origin.

We shift the parent function down so that its vertex is now at (0,-12) to get the graph of $f(x)=|x|-12$ .

See attachment for the graph of $f(x)=|x|-12$ on the specified interval.
