Answer:
6√3
Step-by-step explanation:
V = 648•(3½) = 8•81•(3½) where the SQUARE ROOT OF 3 has been written with a fractional exponent V = s3
so s = cube root of this V.
Cube root of 8 is 2; cube root of 81 is 3•3^(1/3) and cube root of square root of 3 is 3^(1/6).
Therefore s = 2•3•3^(1/3 + 1/6) = 2•3•3½ = 6√3.
You will need to get s2 = 36•3 = 108. Finally, T.S.A. = 6 s2 = 6(108) = 648.

Answer:
Step-by-step explanation:
The 270° CCW rotation is described by the transformation ...
(x, y) ⇒ (y, -x)
That is, the first row of the transformed coordinate matrix is the same as the second row of the input matrix. The second row of the output matrix is the opposite of the first row of the input matrix.
Answer:
Step-by-step explanation:
X^4 - 10X^2 + 9 =0 This factors. It just looks odd.
(x^2 - 1)(x^2 - 9) = 0
x^2 - 1 = (x + 1)(x - 1) = 0
x = 1 and x = - 1
x^2 - 9 = (x + 3)(x - 3) = 0
x = 3
x = -3
The correct answer is C (third one down).
I think the answer is 30....Not sure
