A students work to simplify a radical is shown below. Select the statemmebt which best applies to rhe sample mathematical work
Alik [6]

Answer:

D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further.

Step-by-step explanation:

If you add all the exponents of y in first line then we get

4+4+4+4+4+3=23

Which is same as the exponent in original problem.

So first line is good.

Since it is 4th root so each y^4 will turn into y when it moves out of the radical so final answer is correct.

Hence correct choice is "D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further." is the correct answer.

Which solids have infinitely many planes of symmetry? Check all that apply. right square pyramid cube right cylinder right hexag
allsm [11]

The answer is: Sphere and Right cylinder.

The explanation for this answer is shown below:

By definition, the numbers of planes of symmetry depends of each solid (a figure of three dimensions). The plane of symmetry divides the solid into two congruent halves which have mirror images.

Based on the information above, a cube has nine plane of symmetry, a square pyramid has four planes of symmetry, the hexagonals prims have thirteen and the spheres a cylinders have infinite number of plane of symmetry.
