Answer:
50°
Step-by-step explanation:
In a parallelogram opposite angles have the same measure. Angle ABC has then the same measure of angle ADC, which is 38°+12°=50°
The smaller wheel rolled
.. 4*2πr = 8πr . . . . feet
The larger wheel rolled
.. 4*2π*2r = 16πr . . feet
The larger wheel traveled (16πr -8πr) = 8πr feet farther than the small wheel.
Answer:
its A.
Step-by-step explanation:
Answer:
The coordinates are
and
.
Step-by-step explanation:
First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:
(1)
Where
is the vector translation.
If we know that
and
, then the vector translation is:



Then, we determine the coordinates for Y' and Z':






The coordinates are
and
.
