Step-by-step explanation:
The slope-point form: y - y₁ = m(x - x₁).
The slope-intercept form: y = mx + b.
![k:y=m_1x+b_1,\ l:y=m_2x+b_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}](https://tex.z-dn.net/?f=k%3Ay%3Dm_1x%2Bb_1%2C%5C%20l%3Ay%3Dm_2x%2Bb_2%5C%5C%5C%5Cl%5C%20%5Cperp%5C%20k%5Ciff%20m_1m_2%3D-1%5Cto%20m_2%3D-%5Cdfrac%7B1%7D%7Bm_1%7D)
We have:
and the point (-5, 7)
therefore ![m_2=-\dfrac{1}{-4}=\dfrac{1}{4}](https://tex.z-dn.net/?f=m_2%3D-%5Cdfrac%7B1%7D%7B-4%7D%3D%5Cdfrac%7B1%7D%7B4%7D)
![y-7=\dfrac{1}{4}(x-(-5))\\\\\boxed{y-7=\dfrac{1}{4}(x+5)}\to\boxed{B.}](https://tex.z-dn.net/?f=y-7%3D%5Cdfrac%7B1%7D%7B4%7D%28x-%28-5%29%29%5C%5C%5C%5C%5Cboxed%7By-7%3D%5Cdfrac%7B1%7D%7B4%7D%28x%2B5%29%7D%5Cto%5Cboxed%7BB.%7D)

Answer:
0.9974
Step-by-step explanation:
![arcsin( \frac{1}{7} ) = 0.1433 \\ cos( \frac{0.1433}{2} ) = 0.9974](https://tex.z-dn.net/?f=arcsin%28%20%5Cfrac%7B1%7D%7B7%7D%20%29%20%3D%200.1433%20%5C%5C%20cos%28%20%5Cfrac%7B0.1433%7D%7B2%7D%20%29%20%3D%200.9974)
