Anvisha [2.4K]
Answer: Volume=502.7 oz



Explanation: We need to find the volume of this cylinder to answer the question.

The general formula for the volume of a cylinder is V=πr^2h

Substituting gives us V=π*8*20, then V=160π and finally V=502.6548246 oz cubed

Prove that x-1 is a factor of x^n-1 for any positive integer n.
PolarNik [594]

Answer:    

x-1 is a factor of x^n - 1

Step-by-step explanation:

x-1 is a factor of x^n - 1

We will prove this with the help of principal of mathematical induction.

For n = 1, x-1 is a factor x-1, which is true.

Let the given statement be true for n = k that is x-1 is a factor of x^k - 1.

Thus, x^k - 1 can be written equal to  y(x-1), where y is an integer.

Now, we will prove that the given statement is true for n = k+1

x^{k+1} - 1\\=(x-1)x^k + x^k - 1\\=(x-1)x^k + y(x-1)\\(x-1)(x^k + y)

Thus, x^k - 1 is divisible by x-1.

Hence, by principle of mathematical induction, the given statement is true for all natural numbers,n.
