Answer:
D.
Step-by-step explanation:
we are given
we can use standard equation of hyperbola
where
center=(h,k)
center at origin
so, h=0 and k=0
vertex is
we can use formula
vertices: (h, k + a)
we get
we can plug k=0
now, we can plug these values
now, we are given it passes through
so, we have
we can plug these values and then we can solve for b
and we get
we can solve for b
and we get
now, we can plug these values
we can simplify it
and we get
Jacob used 1/7 of a liter
of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to
mixed fraction
=> x = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
