Answer:
it is decreasing by 1/2 half every number to get the next answer is 6
Step-by-step explanation:
The height is about 3, since I use 3.14 for (pi)<span>π.</span>
There must be minus sign with 4.9 .
The given equation is the equation of parabola , which is maximum at its vertex, and the formula of vertex is
So the height is maximum at t=2.55 seconds and to find the maximum height , we need to plug 2.55 for t , that is
So the maximum height is 112 m .
Answer:
2 times
Step-by-step explanation:
the length and breadth of the parallelogram will be l and b, respectively.
Then, perimeter = 2(1 + b) [∵ perimeter of parallelogram = 2 x (length + breadth)]
If both sides are increased twice, then new length and breadth will be 21 and 2b, respectively.
Now, new perimeter = 2(21 + 2b) = 2 x 2(l + b) = 2 times of original perimeter.
the perimeter of parallelogram will be increased 2 times.
