The ball's velocity will be represented by the derivative of its distance function:
Now find the times
for which this is equal to 30, i.e. solve
This has two solutions,
, but only one is positive and falls in the interval
![[0,3]](https://tex.z-dn.net/?f=%5B0%2C3%5D)
. So the velocity reaches 30 cm/s when
.
Answer:
7v +1
Step-by-step explanation:
6v+v+1
Combine like terms
7v +1
70,000 grams is 70 kilograms
Basic method is Synthetic Division and Factor Theorem
Step-by-step explanation:
For higher-degree equations, the question becomes more complicated than others: cubic and quadratic equations can be solved by similar formulas.
Hence, to avoid those circumstances we can use Synthetic Division and Factor theorem to determine the squares of the given polynomial those who have order higher than 2.
The next bigger hundred is 500 .
The next smaller hundred is 400.
487 is nearer to 500 .
