Answer:
A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelograms are also trapezoids.
For this case we have the following functions:

We must find
. By definition we have to:

So:

Finally, the composite function is:

Answer:

Answer:
The circumference of Earth's equator is 40,080 km.
Step-by-step explanation:
Given that every 24 hours, Earth makes a full rotation around its axis, and Earth's speed of rotation at the equator is 1,670 km per hour, to determine what is the circumference of Earth's equator the following calculation must be performed:
24 x 1,670 = X
40,080 = X
Therefore, the circumference of Earth's equator is 40,080 km.
