Answer:

3*10^4

Step-by-step explanation:

8.9/3.3 is about 3. 10^8/10^4 is 10^4.

Thus, the answer is about 3*10^4.

Answer: C: 3 X 10^4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left decimal. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal. 2.69 (line over .69), therefore, round you get 3. = 3 x 10^4

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 $n\in\mathbb{N}$ .

Complete factorization

Lostsunrise [7]

Answer:

A. 2x + 1

Step-by-step explanation:

6x³ - 15x² - 9x

3x (2x² - 5x - 3)

3x (2x² + x - 6x - 3)

3x (x (2x + 1) - 6x - 3)

3x (x (2x + 1) - 3 (2x + 1))

= 3x <u>(</u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u><u>)</u> (x - 3)

one of the factor of the complete factorization is <u>A</u><u>.</u><u> </u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u>
