Answer:
The Average Speed of the Ball is 3.925 m/s
Step-by-step explanation:
Add All The Numbers Together
0.2+0.5+5+10
Divide By How Many Measurements There Are
And There Are 4 Measurements
15.7/4 = 3.925
Answer:
y=600,000 x=1
Step-by-step explanation:
y is equal to 600,000 which means that every minute (x) 600,000 gallons of water would pass that point in the river
Answer:
31750
Step-by-step explanation:
Sin ( t ) = √ ( 1 - (-9/11)²) = √ ( 1 - 81/121 )= √ 40/121
sin ( t ) = - 2 √10 / 11
cos ( 2 t ) = cos² t - sin² t = 81/121 - 40 / 121 = 41 /121
sin ( 2 t ) = 2 sin t cos t = 2 · ( - 2 √10/11 ) · ( - 9 /11 ) = 36√10 / 121
cos ( t/2 ) = √( 1 + cos t ) / 2 = 1 /√11
sin ( t/2 ) = √( 1 - cos t ) / 2 = √( 10/11 )
