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.

When ever you combine different elements the chemical properties change because elements are different , unless you combine the exact same elements.
Answer:
See attachment
Step-by-step explanation:
We want to graph
on the interval -10 to 10.
Let
be the parent absolute value function.
We can easily graph
, if we use translation.
When the parent function is shifted downwards by 12 units, we obtain the graph of
.
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
.
See attachment for the graph of
on the specified interval.
The distance between the points is 10.4
