or, alternatively:
8
Two doubled is four. If you double that result four times, you get 4, 8, 16, and finally 32. So, two doubled four times equals 32.
Write the word in which the consonant was doubled before adding -ing.
When the amplitude of a wave is doubled, the energy in the wave increases by a factor of four. This is because the energy in a wave is directly proportional to the square of the amplitude. So, if the amplitude is doubled, the energy will increase by a factor of four.
If the sides of a triangle are doubled then the area becomes quadrupled (four times as large).
the new area will be fourfold, not doubled. try it on squared paper and see how the shape increases from one square into four...
2x+4
1.0 × 1010
well if each side is doubled and the final perimeter is ten, divide ten by four.
I'm just guessing... eight fortieths?
One doubled once is 1*2. One doubled twice is 1*22. One doubled three time is 1*23=8.... One doubled 64 times is 1*264=264, or approximately 1.84*1019, or 18.4 quintillion.
The area increase by four times.
When the diameter of a wire is doubled, its cross-sectional area increases by a factor of four. Resistance is inversely proportional to cross-sectional area, so the resistance would decrease by a factor of four.
