Answer:

A. Quartic

Step-by-step explanation:

I went to desmos graphing,

8x^2+1/9 (plug it in and looked at the line)

It shows a parabola,

y-intercept: (0,0.111)

"Cubic functions. Three points not in a line determine a parabola, a polynomial function of degree 2. Polynomials of degree 2 are quadratic functions. Their graphs are parabolas."

Therefore, this is a quadratic ( quartic) since the degree in this parabola is 2.

h = 3b 

so 1/2 x b x 3b = (1/2)(3b^2) = 150

100 = b^2 

b = square root of 100 = 10 

h = 3b = 3 x 10 = 30</span>
