Trace of a matrix is defined only for a square matrix . It is the sum of the elements on the main diagonal, from the upper left to the lower right, of the matrix
Answer:
2,-2
Step-by-step explanation:
you move 10 x to the left 8 which is now 2
you also move the -6 y up 4 which is now a -2
and end up with 2,-2
I know one of them and it’s size. The lengths do not change when performing a rigid motion. And I believe rigid motions also preserves angles. The angles do not change either.
The answer is c because if the survey says 3 out of 8 have one you divide 3/8 and multiply it by 192.
Answer:
Step-by-step explanation:
Number of reveloutions made in 1 second = 2
Number of revolutions made in 60 seconds ( 1 minute) = 2*60 = 120
Number of revolutions made in (60 minutes) 1 hour = 120 *60 = 7200
Circumference of circle = πd
The distance traveled in 1 revoultion = the circumference of the cirlcle
= 220 cm
The distance travelled in 7200 revoultion = 7200 * 220
=1584000 cm
= 1584000 ÷ 100000
= 15.84 km
= 15.8 km
Speed = 15.8 km/h
