Answer:
<em>2.983 </em>ft/sec
Step-by-step explanation:
Given that
Distance between center and Jasmine riding on a carousal = 9.5 feet
Time taken to complete one rotation = 20 seconds
To find:
Jasmine's linear speed = ?
Solution:
Number of revolutions per minute = 
Formula for linear speed is given as:

Where  is the radius of circular path and
 is the radius of circular path and
 is the number of revolutions per minute.
 is the number of revolutions per minute.

Therefore, the linear speed is <em>2.983 ft/sec.</em>
 
        
             
        
        
        
Answer:
they are both half
Step-by-step explanation:
1 is half of 2 And 4 is half of 8
 
        
             
        
        
        
A) Width = 9/2, length = 10
Rectangle area = length(l)x width(w)
9/2 = 4.5 
4.5(l) x 10(w) = 45ft
        
             
        
        
        
Step-by-step explanation:
2tan 30° / 1 + tan² 30° =
2(⅓√3) /1 + (⅓√3)² =
⅔√3 / 1+ ⅓ =
⅔√3 / 4/3 =
2/4 √3 =
½√3 = sin 60° (proven)
