When thinking about rotational symmetry, you must remember that rotational symmetry means if you are given a figure, and you turn the figure, you end up with the same figure. This happens when you have regular polygons, and each angle is congruent. In order to find the angle of rotation, you divide 360 by the number of angle you are given. if you rotated 360 degrees, that means 360/360=11. Your figure only had one angle, so it can't even be a polynomial! Also, every figure in the world will look exactly like it started if rotated 360 degrees, so this would not be logical.
Answer:
C = 159600
Step-by-step explanation:
Because its Y=2 (10) square so times by its self.
Answer:
1,174.958 gallons
Step-by-step explanation:
Begin by finding the volume of the cylinder V= π x r² x h
V = 3.14 x 25 x 2 = 157.08
Then multiply 7.48 gallons per cubic foot
7.48 x 157.08 = 1,174.958 gallons
Answer
Step-by-step explanation:
Law of sines: SinB/15 = SinA/BC
B = 90
A = 180-90-21=69°
BC= (15*SinA)/SinB = (15*sin69)/1 ≈ 14m
For the answer to the question above, the easiest way to determine is changing every runner's speed into the same unit.
<span>First = 10 m/s </span>
<span>Second = 10 miles/min = 16090.34 / 60 m/s (As 1 mile = 1609.34 meter and 1 min = 60 sec) </span>
<span>Second = 260.82 m/s </span>
<span>Third = 10 cm/hr = 10*(0.01)/60*60 (As 1 cm = 0.01 m and 1 hr = 60*60 sec) </span>
<span>Third = 0.000028 m/s </span>
<span>Fourth = 10 km/sec = 10*1000 m/s (As 1 km = 1000 m and time is already in sec) </span>
<span>Fourth = 10000 m/s </span>
<span>So fastest would be the one who covers the largest distance in 1 sec. It would be the fourth one.</span>
