Cos 0 = 12/15. find sin 0.

valentina_108 [34]

Answer:

$sin \theta = \frac{3}{5}$

Step-by-step explanation:

$cos \theta = \frac{12}{15}\\\\cos^2 \theta = 1 - sin^2 \theta\\\\sin^2\theta = 1 - cos^2 \theta\\\\$

$= 1 - (\frac{12}{15})^2\\\\= 1 - \frac{144}{225}\\\\= \frac{225 - 144}{225}\\\\=\frac{81}{225}$

$sin \theta = \sqrt{\frac{81}{225}} = \frac{9}{15} = \frac{3}{5}$

Express x^2-5x-24 as the product of two binomials

NeTakaya

Expressing a quadratic equation as the product of two binomials is the same thing as factoring.
<span>The answer would be (x+3)(x-8) because if you multiply it out, x times x is x^2, -8x+3x is -5x, and -8 times 3 is -24. </span>
To multiply is out, you FOIL, or muliply the First terms in the two binomials (the x's), the the Outer terms (the x and the -8), then the Inner terms (the 3 and the x), and finally the Last terms (the 3 and the -8).<span>so it's (x-8)(x+3)</span>
