Answer:
4 seconds
Step-by-step explanation:
using the vertex formula of a quadratic,
, where (h,k) is the vertex
h is height and t is time in seconds
the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)
Height of 1/2
time of 2 seconds
it will take 2 additional seconds to reach the water again.
this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.
Counting backwards next is 1
C.
If each 1/2 is cut in 4 than you would have to multiply that by 2 because it's only half. Then since you're finding what fraction is it you would put a 1 on top and say 1/8.
Answer:
tbh i like the first one its so simple but like so nice at the same time
