To find the vertex, you need to find the axis of symmetry first.
In order to find the axis of symmetry we have to do -b/2a.
In our case, the b is -8 and the a is 1.
Plug it in.
-(-8)/2(1)
8/2 = 4
Our axis of symmetry is 4.
Now, we plug it into the equation to find the rest of the vertex.
y = 4^2 - 8(4) + 1
y = 16 - 32 + 1
y = -16 + 1
y = -15
Put it together.
Our vertex is (4,-15).
Answer: There will be $ 1687.02 in the account after 7 years.
Step-by-step explanation:
Formula to find the accumulated amount (A) in account on principal amount (P) with rate of interest (r) in 't' years is given by :-
As per given, P = $1400
r= 2.7% = 0.027
t= 7 years
Then,
Hence, there will be $ 1687.02 in the account after 7 years.

<u></u>
<u>Double number line is a diagram used when. quantities have different units.</u>
<u></u>
<u>It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.</u>
<u></u>
<u>some ratios equivalent to 1:3 are;</u>
