Answer:
6x¹⁰ - 96x²
6x²(x⁸ - 16)
B) 6x²(x⁸ - 16)
6x²[(x⁴)² - 4²]
6x²[(x⁴ - 4)(x⁴ + 4)]
6x²(x⁴ + 4)[(x²)² - 2²]
6x²(x⁴ + 4)(x² - 2)(x² + 2)
Each octave in the piano is composed of 8 keys with the end key overlapping the next one which means the last key is the first key of the next octave. In 52 white keys, there are 7 octaves which is composed of 43 full keys and 7 overlapping keys. Answer to this problem is 7 octaves.
Your answer would be r = 12/7 ≈ 1.71
Firstly you need to write an equation involving r and t. They tell you that r varies inversely with t, which means r = k/t, where k is some constant.
We can find k by substituting in the values for r and t that they give us:
r = k/t
2 = k/(-6)
-12 = k
Now the equation is r = -12/t. We can then substitute in t as -7 to get the final answer:
r = -12/t
r = -12/(-7)
r = 12/7 ≈ 1.71
