What are the solutions of this equation 16-2x^2=-64
xenn [34]

Answer:

x = ± 2\sqrt{10}

Step-by-step explanation:

Given

16 - 2x² = - 64 ( subtract 16 from both sides )

- 2x² = - 80 ( divide both sides by - 2 )

x² = 40 ( take the square root of both sides )

x = ± \sqrt{40} = ± \sqrt{4(10)} = ± 2\sqrt{10}

A cone and a cylinder have the same base and height, as shown below.
marshall27 [118]

The statement that apply is that the volume of the cone is One-third the volume of the cylinder

<h3>How to find the volume of a cone and cylinder?</h3>

volume of a cone = 1 / 3 πr²h

where

  • r = radius
  • h = height of the cone

Volume of a cylinder = πr²h

where

  • r = radius
  • h = height

The cone and the cylinder has the same base and height. Therefore, the radius and height are the same .

volume of the cylinder = 84π

Therefore, the volume of the cone is One-third the volume of the cylinder.
