<u>Answer:</u>

<em><u>243, 729</u></em>

<u />

<u>Explanation:</u>

To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.

Take a look at the sequence given:

<em>1, 3, 9, 27, 81,...</em>

<em />

Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.

<em>1 - first term</em>

<em>3 - second term</em>

<em />

<em>1 ? ? = 3</em>

<em>1 × 3 = 3</em>

<em />

So, this means the sequence multiplied three to get the next term. Therefore, the pattern should be 'multiply three' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.

<em>1, 3, 9, 27, 81,...</em>

<em />

<em>1 </em><em>× 3 = </em><em>3</em>

<em>3 </em><em>× 3 = </em><em>9</em>

<em>9</em><em> × 3 = </em><em>27</em>

<em>27</em><em> × 3 = </em><em>81</em>

<em />

So, since 'multiply three' every time gives us the next term, the pattern is correct.

Finally, let's continue the pattern to find the next two terms.

<em>81</em><em> × 3 = </em><em>243</em>

<em>243 </em><em>× 3 = </em><em>729</em>

<em />

Therefore, the next two terms in the sequence are <u><em>243, 729.</em></u>

The value of tangent x is given. Find sine x and cos x if x lies in the specified interval.
katrin2010 [14]

Answer:

sin x = 0.998

cosx = 0.046

Step-by-step explanation:

<u>Given that:</u>

tan x = 21

where interval of x is [0,\dfrac{\pi}{2}].

We know that the trigonometric identity for tan x is:

tan\theta = \dfrac{Perpendicular}{Base}

Comparing with:

tan x = \dfrac{21}{1}

Perpendicular = 21 units

Base = 1 unit

As per pythagorean theorem:

\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\

\Rightarrow \text{Hypotenuse}^2 = 21^2 +1^2\\\Rightarrow \text{Hypotenuse} = \sqrt{442} = 21.023\ units

interval of x is [0,\dfrac{\pi}{2}] so values of sinx and cosx will be positive because it is first quadrant where values of sine and cosine are positive.

We know that

sin\theta = \dfrac{Perpendicular}{Hypotenuse}\\cos\theta = \dfrac{Base}{Hypotenuse}

So, sine x :

\Rightarrow sinx =\dfrac{21}{21.023}\\\Rightarrow sinx = 0.998

Similarly, value of cos x :

\Rightarrow cosx =\dfrac{1}{21.023}\\\Rightarrow cosx = 0.046

How do you solve 5x + 7 = 2x + 1​
quester [9]

Answer:

x = -2

Step-by-step explanation:

5x + 7 = 2x + 1

subtract both sides by 2x

3x + 7 = 1

subtract both side by 7

3x = -6

divide both sides by 3

x = -2

Which equation in point-slope form contains the point (–3, 5) and has slope –1? y + 3 = –1(x – 5) y – 5 = –1(x + 3) y – 3 = –1(x
andreev551 [17]

Answer:

y - 5 = -1(x + 3)

Step-by-step explanation:

Point slope form

y - y1 = m(x - x1) where m = slope and passing through point (x1 , y1)

In this case if the equation in point-slope form contains the point (–3, 5) and has slope –1 then the equation should be:

y - 5 = -1(x - (-3))

y - 5 = -1(x + 3)
