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
Answer:
184
Step-by-step explanation:
edmund as a 2 by 2 cube
so samuel has a cuboid twice as long
2 x 2 = 4
3 times as wide
3 x 2 = 6
and 4 times as high
2 x 4 = 8
8 x 6 x 4 = 192 small cubes
but we are trying to find how much more samuel got
so 192 - 8 = 184
Answer:
pretty sure its D. 1.6 x 10^9
Answer:
Gene ran faster
Step-by-step explanation:
The fastest time is the smallest time since they ran the same distance
gene ran 90 meters in 16.3 seconds.
alma ran 90 meters in 17.2 seconds
16.3 < 17.2
Gene ran faster
