Let P(n) be the statement that n! < nn where n is an integer greater than 1.
Ira Lisetskai [31]

Answer: See the step by step explanation.

Step-by-step explanation:

a) First, Let P(n) be the statement that n! < n^n

where n ≥ 2 is an integer (This is because we want the statement of P(2).

In this case the statement would be (n = 2): P(2) = 2! < 2^2

b) Now to prove this, let's complet the basis step:

We know that 2! = 2 * 1 = 2

and 2^2 = 2 * 2 = 4

Therefore: 2 < 4

c)  For this part, we'll say that the inductive hypothesis would be assuming that k! < k^k for some k ≥ 1

d) In this part, the only thing we need to know or prove is to show that P(k+1) is also true, given the inductive hypothesis in part c.

e) To prove that P(k+1) is true, let's solve the inductive hypothesis of k! < k^k:

(k + 1)! = (k + 1)k!  

(k + 1)k!  < (k + 1)^k  < (k + 1)(k + 1)^k

Since k < k+1 we have:

= (k + 1)^k+1

f) Finally, as the base and inductive steps are completed, the inequality is true for any integer for any n ≥ 1. If we had shown P(4)

as our basis step, then the inequality would only be proven for n ≥ 4.

Rectangle with a width of 36 centimeters and a perimeter of 80 centimeters
olga2289 [7]

Answer: Height = 4 centimeters

Area = 144 cm^2

Step-by-step explanation:

So we know that on a rectangle opposite sides are equal in distance.

If one side of the rectangle is 36 centimeters then that means the opposite side is also 36 centimeters.

36 + 36 = 72 centimeters

The perimeter is the sum of all sides, so two out of the four of our sides total to 72 centimeters. So the remaining length of both sides is as follows:

80 - 72 = 8

The sum of the remaining sides is 8 so divide it between the two and that is the height.

8/2 = 4

I'm not sure what the question wants so here is pretty much everything:

Height: 4 cm

Area: 144 cm^2
