Answer:
figuring medicine doses, patient vitals, etc.
Step-by-step explanation:
Answer:
x = 0.75.
Step-by-step explanation:
y = 4x^2 - 6x + 3.
( I have assumed that the first term is 4x^2 not 4x).
Convert to vertex form:
y = 4(x^2 - 1.5x) + 3
y = 4[ (x - 0.75)^2 - 0.5625 ] + 3
y = 4(x - 0.75)^2 - 2.25 + 3
y = 4(x - 0.75)^2 + 0.75.
So the axis of symmetry is x = 0.75.
The stone takes 4sec to reach the water level.
initial velocity (u)=0
time(t)=4s
acceleration due to gravity(a)=
9.8(10 approx)
so,its final velocity will be
v=u+at
0+10×4=40
v=40m/s
