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.
Answer:
B) x + 1/y times h/g+1
Step-by-step explanation:
We need to divide by
then match with given choices to find the correct equivalent result.
where given choices are:
A) x/y times h/g
B) x + 1/y times h/g+1
C) x+ 1/y divided h/g+1
D) y/x+1 divided g+1/h
So let's divide by
we are allowed to flip the bottom fraction and change division sign into multiplication. So we get:
Hence correct choice is: B) x + 1/y times h/g+1
Answer:
X=6
Step-by-step explanation:
It is under enlargement and reduction
Therefore we can equates sides because of the parallel lines
Cross multiply
dividing through by 12
simplify
