Find x in the given figure if m∠AOC = 130°. Question 7 options: A) –14 B) 8 C) 10.5 D) 14
soldi70 [24.7K]

Answer:

B) x=8

Step-by-step explanation:

To solve, we must find x like so:

We know that angle AOC = 130, so adding AOB and BOC will equal 130, then we solve for x.

(6x-5)+(8x+23)=130\\6x-5+8x+23=130\\14x+18=130\\14x=130-18\\14x=112\\x=\frac{112}{14}\\x=8

How to determine whether the given function is even,odd, or neither?<br>f(x) = x^3 + x^2 + 3
Gnom [1K]

f(x) = x^3 + x^2 + 3x^0 is neither even nor odd.  Why?  Because we have a mixture of even and odd powers of x here:  x^3 (odd) and x^2 and x^0 (even).

Even functions:  all component functions are even (e. g., x^2 and x^0).

Odd functions:  all component functions are odd (e. g., x^5 and x^3.

Neither:              There's a mixture of even ad odd functions.


Another way to test for even, odd or neither:

Even functions:  f(-x) = f(x).  Changing the sign of the input (x) doesn't change the sign of the output.

Odd functions:  f(-x) = -f(x).  Changing the sign of the input changes the sign of the output.

Find exact value of cos
mylen [45]
<h3>Answer: Choice B. \frac{\sqrt{91}}{10}</h3>

Work Shown:

\sin^2 \theta + \cos^2 \theta = 1\\\\\left(\frac{3}{10}\right)^2 + \cos^2 \theta = 1\\\\\frac{9}{100} + \cos^2 \theta = 1\\\\\cos^2 \theta = 1 - \frac{9}{100}\\\\\cos^2 \theta = \frac{100}{100}-\frac{9}{100}\\\\\cos^2 \theta = \frac{91}{100}\\\\\cos \theta = \sqrt{\frac{91}{100}} \ \text{ cosine positive in Q1}\\\\\cos \theta = \frac{\sqrt{91}}{\sqrt{100}}\\\\\cos \theta = \frac{\sqrt{91}}{10}\\\\
