Answer:
Step 2
Step-by-step explanation:
The quadratic formula is given by 
Our equation is y = 2x²-x-6
So here our a = 2, b = -1, and c = -6
We can now plug these numbers into our formula
Step 2 is incorrect because it states that "x equals the negative of negative 1 plus or minus the square root of negative one plus forty-eight all over two times 2."
The correct statement would be "x equals the negative of negative 1 plus or minus the square root of positive one plus forty-eight all over two times 2.", because the square of a negative is positive, resulting in a positive one.
Since this step is incorrect, the steps after are also incorrect, but Harry went wrong at Step 2
Hi there!
Parabola x² = 12y
→ x² = 4ay
→ 4a = 12
→ a = 12÷4
→ a = 3
So, the co-ordinates of the focus is:-
S(0,a)=(0,3)
→ Let AB be the latus rectum of the given parabola.
→ Coordinates of end-points of latus rectum are (-2a,a), (2a,a)
→ Coordinates of A are (-6,3), while B's coordinates are (6,3).
→ ∆OAB are O(0,0), A(-6,3), B(6,3)
Area of ∆OAB is :-

Answer:
$10496.77
Step-by-step explanation:
We have been given that Barbara puts $200 into an account every month that pays 4.5% interest, compounded monthly.
To find the money in the account after 4 years, we will use future value formula.
, where,
R = Regular deposits,
r = Interest rate in decimal form
n = Number of times interest in compounded per year,
t = Time in years.
Substitute given values:
Therefore, there will be an amount of $10496.77 in the account after 4 years.
