Use an induction proof to prove this statement:<br> For n≥1, 4^n+5 is divisible by 3.

Tpy6a [65]

Answer:

See below

Step-by-step explanation:

We shall prove that for all $n\in\mathbb{N},3|(4^n+5)$ . This tells us that 3 divides 4^n+5 with a remainder of zero.

If we let $n=1$ , then we have $4^{1}+5=9$ , and evidently, $9|3$ .

Assume that $4^n+5$ is divisible by $3$ for $n=k, k\in\mathbb{N}$ . Then, by this assumption, $3|(4^n+5)\Rightarrow4^k+5=3m,\: m\in\mathbb{Z}$ .

Now, let $n=k+1$ . Then:

$4^{k+1}+5=4^k\cdot4+5\\=4^k(3+1)+5\\=3\cdot4^k+4^k+5\\=3\cdot4^k+3m\\=3(4^k+m)$

Since $3|(4^k+m)$ , we may conclude, by the axiom of induction, that the property holds for all $n\in\mathbb{N}$ .

Find the values of x and y

Elanso [62]

3x-11 =2x+11
x=22

y = 180 - [{3(22)-11} +{2(22)+11}]
y= 180 - 110
y = 70

Therefore: x=22 and y = 70

Liula [17]

Answer:

$300,000.

Step-by-step explanation:

He sold it for 98% of what he paid for it.

So if the cost price is $x:

0.98x = 294,000

x = 294,000 / 0.98

= $300,000.
