Given :
A particle moves in the xy plane starting from time = 0 second and position (1m, 2m) with a velocity of v=2i-4tj .
To Find :
A. The vector position of the particle at any time t .
B. The acceleration of the particle at any time t .
Solution :
A )
Position of vector v is given by :

B )
Acceleration a is given by :

Hence , this is the required solution .
The answer to the question is 6/9.
If 200 acres is 50% and 100 is 25% divide that by 5 and 5% is 20 so 25% (100 acres) plus 5% (20 acres) equals 30% (120 acres) so it's 30%
Answer:
A. (x - 3)(x + 3)
Step-by-step explanation:
From the graph the x-axis is crossed by the graph at different points which are;
x = 3 and x = -3
This means the solutions are : x = 3 and x =-3
The factors will form the following equation : (x - 3)(x + 3)

The fact that it can turn its head 180 degrees is just extra information. They tell us that it is 10.5 cm long. What they're asking for is the length in a mixed number, so 10.5 as a mixed number.
