For this case we have the following equation:
H (t) = - 16t ^ 2 + 28t
When the dolphin finishes a jump, then the height is equal to zero.
We have then:
-16t ^ 2 + 28t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 1.75 s
Therefore, the dolphin takes 1.75 seconds to make a jump.
Answer:
it will take for the dolphin to make one jump about:
t = 1.75 s
When an account is rounded off to its nearest dollar will
change based on the place value.
For example, the given account of money if $ 56 730, then it
will be rounded to its nearest ten thousands. Then the given amount will be
rounded to $57,000 in where the given money rounded up and gain up to $300. But
if the money will be rounded with its nearest hundreds, the money will become $
56,700. Notice that the given money rounded down and lost $30 dollars.
