We know that
the quadratic function in vertex form is--------------> y=a*(x-h)²+k
we have
f(x)=x²<span>+14x+40
y=</span>x²+14x+40
We can convert to vertex form by completing the
square on the right hand side
y-40=x²+14x
y-40-49=x²+14x-49------> subtract 49 on BOTH sides to
preserve the equality
y-40=(x²+14x+49)-49
y=(x²+14x+49)-49+40---------> y=(x+7)²-9
the answer is
the quadratic function in vertex form-----------> y=(x+7)²-9
<span>the vertex is the point (-7,-9)

Answer:
45$
Step-by-step explanation:
100% is the exact same as last moth. 150% is last moths plus half therefor 30/2 is 15. 15 + 30 = 45

Answer: 20 students each year
Step-by-step explanation:
60+20= 80
80-60=20
you can do 80 minus 60 and get 20
then to double check you can add 60 and 20
Acceleration = change in velocity / time
a: acceleration
Vf: final velocity
Vi: initial velocity
t: time
a = (Vf - Vi) / t
a = (3.3 - 0) / 15
a = 0.22 m/s^2
