The cube root function shift left 2 and up 3
ivolga24 [154]

Answer: f(x) = 3\sqrt{x+2} +3

Step-by-step explanation: 3\sqrt{x+2} +3

(assume that the three in front is a part of the cube root function)

In order to shift a parent function to the left two you need to add it on the inside (in this case underneath the cube root). Adding on the inside does the opposite if you were adding on the outside, so instead of moving it to the right, it moves it left. In order to slide a function up or down you need to add or subtract a number on the outside of the function. In this case you need to add 3 at the end.

Let alpha and beta be conjugate complex numbers such that frac{\alpha}{\beta^2} is a real number and alpha - \beta| = 2 \sqrt{3}
miskamm [114]

Answer:

-3+i\sqrt{3} , 1+\sqrt{3}

Step-by-step explanation:

Given that alpha and beta be conjugate complex numbers

such that frac{\alpha}{\beta^2} is a real number and alpha - \beta| = 2 \sqrt{3}.

Let

\alpha = x+iy\\\beta = x-iy

since they are conjugates

\alpha-\beta = x+iy-(x-iy)\\= 2iy= 2i\sqrt{3} \\y =\sqrt{3}

\frac{\alpha}{\beta^2} }\\=\frac{x+i\sqrt{3} }{(x-i\sqrt{3})^2} \\=\frac{x+i\sqrt{3}}{x^2-3-2i\sqrt{3}} \\=\frac{x+i\sqrt{3}((x^2-3+2i\sqrt{3}) }{(x^2-3-2i\sqrt{3)}(x^2-3-2i\sqrt{3})}

Imaginary part of the above =0

i.e. \sqrt{3} (x^2-3)+2x\sqrt{3} =0\\x^2+2x-3=0\\(x+3)(x-1) =0\\x=-3,1

So the value of alpha = -3+i\sqrt{3} , 1+\sqrt{3}

Help Answer This Question For 20 Points
marissa [1.9K]

Answer:

A

Step-by-step explanation:

When we rotate anything, at least one part/face of it will become spherical/circular. In this case, the exterior of the shape will become circular when we rotate about line m.

A 3D shape with the above description is a cylinder. So, cross off C, D, and E. Now, when we rotate this figure to get the cylinder, the top is a circle. Since the figure is simply being rotated, the radius is not lengthened or shortened; it stays the same.

Therefore, the radius of the cylinder is still 5.

Thus, the answer is A.

Hope this helps!
