Please red the answer below
Step-by-step explanation:
In order to determine the length of each cable you use the Newton second law for each component of the forces involved in the situation.
For the x component you have:
(1)
T1: tension of the first cable = 1500N
T2: tension of the second cable = 800N
θ1: angle between the horizontal and the first cable
θ2: angle between the horizontal and the first cable
For the y component you have:
(2)
W: weight of the camera = Mg = (140kg)(9.8m/s^2) = 1372N
You can squared both equations (1) and (2) and the sum the two equations:
Then, you sum the equations:
(3)
Next, you use the following identity:
and you obtain in the equation (3):
With this values you can calculate the value of the another angle, by using the equation (1):
Now, you can calculate the length of each cable by using the information about the width of the football field. You use the following trigonometric relation:
d: distance to the right side of the field
By using the cosine law you can fins a system of equation and then you can calculate the values of l1 and l2.
Answer:
(A) n(Eᶜ)=40
Step-by-step explanation:
The Sample Space for is given as:
(1,2),(1,3),(1,4),(1,5),(1,6),(1,7),(1,8),(1,9),(1,10),(1,11)
(2,3),(2,4),(2,5),(2,6),(2,7),(2,8),(2,9),(2,10),(2,11)
(3,4),(3,5),(3,6),(3,7),(3,8),(3,9),(3,10),(3,11)
(4,5),(4,6),(4,7),(4,8),(4,9),(4,10),(4,11)
(5,6),(5,7),(5,8),(5,9),(5,10),(5,11)
(6,7),(6,8),(6,9),(6,10),(6,11)
(7,8),(7,9),(7,10),(7,11)
(8,9),(8,10),(8,11)
(9,10),(9,11)
(10,11)
n(S)=55
Event E is the Event that the two numbers are odd.
Therefore: Complement of E will be the event that any of the two numbers is even.
The Sample Space of the complement of E is:
Therefore:
n(Eᶜ)=40
