Step-by-step explanation:
We have given the vertices of a parabola
General equation of parabola is:
Here, (h,k) is vertex of the parabola
Here, h=1 and k=2 and a=1
On substituting the values in the general equation of the parabola we get:
Therefore, option 2nd is correct.

Answer:
The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.
215 of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.
215×31=615 of a mile
615=25 of a mile
You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.
Look at what happens:
215÷20×60
=215×120×603
=215×3 ← exactly the same maths.
=25
Y less than 21 = 21 - y
Remember, "less than" indicates a subtraction with the terms in inverted order.
Hope I helped!
