Answer:

D.   -\sqrt{17}/8

Step-by-step explanation:

Draw a right triangle such that cos (theta) = 8/9.  That means the hypotenuse = 9 and the adjacent side to theta = 8

Use the Pythagorean theorem to find the opposite side to theta

\sqrt{9^{2} - 8^{2} }  = \sqrt{81 - 64}  = \sqrt{17}

tan (theta) = \sqrt{17}/8

Since theta is in quadrant IV, the tan is negative.  So, tan (theta) = -\sqrt{17}/8

Is the following relation a function?
Dafna1 [17]
Hello!

If x represents the domain while y represents the range, this is not a function. Each input can have only one output. Outputs can have multiple inputs, but not the other way around.

As you can see, -1 goes to both 2 and -1, so it is not a function.

I hope this helps!

Type the correct answer in each box.
Harlamova29_29 [7]

Answer/Step-by-step explanation:

✔️(3x² - 7x + 14) + (5x² + 4x - 6)

3x² - 7x + 14 + 5x² + 4x - 6 (distributive property)

Add like terms

3x² + 5x² - 7x + 4x + 14 - 6

8x² - 3x + 8

Therefore:

✅(3x² - 7x + 14) + (5x² + 4x - 6) is equivalent to expression 8x² - 3x + 8.

✔️(2x² - 5x - 3) + (-10x² + 2x + 7)

2x² - 5x - 3 - 10x² + 2x + 7 (distributive property)

Add like terms

2x² - 10x² - 5x + 2x - 3 + 7

-8x² - 3x + 4

Therefore:

✅(2x² - 5x - 3) + (-10x² + 2x + 7) is equivalent expression to -8x² - 3x + 4

✔️(12x² - 2x - 13) + (-4x² + 5x + 9)

12x² - 2x - 13 - 4x² + 5x + 9

12x² - 4x² - 2x + 5x - 13 + 9

8x² + 3x - 4

Therefore:

✅(12x² - 2x - 13) + (-4x² + 5x + 9) is equivalent expression to 8x² + 3x - 4
