Find the length of the radius of the following circle. (x + 2)2 + y2 = 10 5 √(10) 100
Makovka662 [10]

<span>For this case we have the following equation:</span>

<span> (x + 2) 2 + y2 = 10</span>

<span> We must remember that the standard equation of the circle is given by:</span>

<span> (x - h) 2 + (y - k) 2 = r2</span>

<span> Where r is the radius.</span>

<span> Therefore, in the given equation the radius is:</span>

<span> r ^ 2 = 10</span>

<span> Clearing we have:</span>

<span> R = root (10)</span>

<span> Answer:</span>

<span> The length of the radius of the circle is:</span>

<span><span> √ (10)</span></span>

Simplify the expression
chubhunter [2.5K]

Answer:

  sin(α) -cos(α)

Step-by-step explanation:

\dfrac{2\sin^2{\alpha}-1}{\sin{\alpha}+\cos{\alpha}}=\dfrac{(2\sin^2{\alpha}-1)(\sin{\alpha}-\cos{\alpha})}{(\sin{\alpha}+\cos{\alpha})(\sin{\alpha}-\cos{\alpha})}\\\\=\dfrac{(2\sin^2{\alpha}-1)(\sin{\alpha}-\cos{\alpha})}{\sin^2{\alpha}-\cos^2{\alpha}}=\dfrac{(2\sin^2{\alpha}-1)(\sin{\alpha}-\cos{\alpha})}{\sin^2{\alpha}-(1-\sin^2{\alpha})}\\\\=\dfrac{(2\sin^2{\alpha}-1)(\sin{\alpha}-\cos{\alpha})}{2\sin^2{\alpha}-1}\\\\=\sin{\alpha}-\cos{\alpha}
