Answer:
Not the same.
Step-by-step explanation:
Given that there is a rotation of 180 degrees . To check whether this is a reflection over the y axis.
Reflection over the y axis make the coordinates (x,y) as (-x,y)
i.e. this means rotation of 180 degrees about the origin anticlockwise.
Hence just rotation of 180 degrees is not the same as a reflection over y axis.
The conditions are:
i) 180 degree to be rotated anticlockwise
ii) Rotation is about the origin
Hence a rotation of 180 degrees need not always be the same as reflection over y axis.
Around $634.85 per year
Because:
$32.85+$35(12 months)+$3.5(52 weeks in a year)= Total cost per year
$420 $182
$32.85 + $420 + $182 = $634.85 per year
First triangle=bxh/2
=3x4/2
=6in squared
rectangle=l x w
=3 x 10
=30in squared
trapezoid=3+5x2/2
=8in squared
6 + 30 + 8
=44 in squared
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>
