Answer:
Step-by-step explanation:
Given that both men moves at constant speed on the same trail, the motion equations that describes each motion are, respectively:
Man 1
Man 2
Where x is measure in kilometers and t in hours, respectively.
The time taken for both men to meet each other is:
Answer:
sorry cant help not sorry
Step-by-step explanation:
H=-16t^2+56t+1, the airplane is shot up from a platform 1 foot above the ground, so 1= - 16t^2+56t+1, we solve this equation
(- 16t+56)t=0, (- 16t+56)=0 or t=o, - 16t+56=0, implies t =3.5s
so the answer is C)3.5 seconds
Answer:
the missing terms:8 and -13
common difference:-7
Step-by-step explanation:
the difference between the first and the second term is:15-22=-7
the difference between the fourth and fifth term is -6-1=-7
so the difference between the third and second term is -7
1-x=-7 so x=8
so the difference between the fifth and sixth term is -7
x-(-6)=-7 so x= -7-6=-13
