write a quadratic function whose given vertex and a
point are as follows:
1.) vertex: (4,-1) point: (3,3)
2.) vertex: (-5,2) point: (-3,3)
3.) vertex: (-5,-3) point: (-4,-5)

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

b is the right answer

a≈380.13mi² would be your answer if the radius was 11 miles
