Answer:
The required position of the particle at time t is: 
Step-by-step explanation:
Consider the provided matrix.
The general solution of the equation 
Substitute the respective values we get:
Substitute initial condition 
Reduce matrix to reduced row echelon form.
Therefore, 
Thus, the general solution of the equation
The required position of the particle at time t is:
Answer:
t = 17.3
Step-by-step explanation:
The following data were obtained from the question:
Angle T = 87°
Opposite T = t =?
Opposite V = v = 14
Opposite U = u = 11
The value of t can be obtained by using cosine rule formula as shown below:
t² = v² + u² – 2vu CosT
t² = 14² + 11² – 2 × 14 × 11 × Cos87°
t² = 196 + 121 – 308 × Cos87°
t² = 317 – 16.119
t² = 300.881
Take the square root of both side
t = √300.881
t = 17.3
Therefore, the value of t is 17.3
Answer:
155
Step-by-step explanation:
Remember that below sea level means negative. So 120-(-35)=155
