The value of a is 1/4 and the equation of the parabola is (x-2)² = (y+2)
<h3>What is a Parabola ?</h3>
A parabola is a u shaped curve. It is a plane curve whose all points are at a fixed distance form a point called focus.
(x-h)² = 4a(y-k)
It is given that the parabola goes through the point (3, -1), and the vertex is at (2, -2).
Therefore
(x -2)² = 4a(y +2)
The parabola passes through the point (3,-1)
(3-2)² = 4*a(-1+2)
1 = 4 a
a = 1/4
The equation of the parabola is
(x-2)² = (y+2)
Therefore The value of a is 1/4 and the equation of the parabola is (x-2)² = (y+2)

I think that the most accurate one is trial 3 since it is the least incorrect and closest percent-wise to the actual correct density of the metal.
Hope this helps!

Answer:
50
Step-by-step explanation:
racket = 5 (5 + 3 = 8)
target = racket = 5
racket * 5 = basket -> 5 * 5 = basket = 25
bowling = basket + basket = 25 + 25 = 50
4(1.75y−3.5)+1.25y
. First multiply through with 4 the numbers in the parentheses.
7y➖ 14 ➕ 1.25y
add 1.25y to 7y
That will be 8.25y
So the answer will be 8.25y ➖ 14
