Since there are 12 inches in a foot, it would be 3/12, or 1/4.
Answer:
The angular speed is 3,227 rad/min
Step-by-step explanation:
Remember that
1 mile=63,360 inches
step 1
Find the circumference of the wheels
The circumference is equal to

we have

substitute


step 2
we know that
The speed of the wheel is 55 mi/h
<em><u>Convert to mi/min</u></em>
55 mi/h=55/60 mi/min
<u><em>Convert to in/min</em></u>
(55/60) mi/min=55*63,360/60 in/min= 58,080 in/min
we know that
The circumference of the wheel subtends a central angle of 2π radians
so
using proportion
Find out how much radians are 58,080 inches

therefore
The angular speed is 3,227 rad/min
I believe that the answer is 2.
Which set of ordered pairs has point symmetry with respect to the origin (0, 0)? (5, 4), (-5, -4) (5, 4), (5, -4) (5, 4), (4, 5)
Sidana [21]
The set of ordered pair that has point symmetry in respect to origin is (5, 4), (-5, -4).
<h3>What is the point of symmetry?</h3>
This is a term that is used to refer to the points that are on the same distance from the origin but are on opposite sides.
The line that connects the points are known to move through the origin such that when measured on the graph, the distances between these points but they are opposite because they are in negatives and positives on the two sides.
