The answer is D. 2101/23.7
2101/23.7 = 88.649789029535864978902953586498
(Which leads to a very precise answer, If I'm wrong... I'm sorry...)

Answer: Vertex is (2,2)</h3>
=====================================
Explanation:
The equation
y = -3x^2 + 12x - 10
is in the form
y = ax^2 + bx + c
with a = -3, b = 12, c = -10
Plug the 'a' and 'b' values into the equation below to find the x coordinate of the vertex
h = -b/(2a)
h = -12/(2*(-3))
h = -12/(-6)
h = 2
The x coordinate of the vertex is h = 2, which is then used to find the y coordinate of the vertex
y = -3x^2 + 12x - 10
y = -3(2)^2 + 12(2) - 10
y = -3(4) + 12(2) - 10
y = -12 + 24 - 10
y = 12 - 10
y = 2
The y coordinate of the vertex is k = 2
The vertex is (h,k) = (2,2)
1 2/3 = 5/3
Divide fraction, multiply reciprocal
5/3 * 8/1 = 40/3
