A line contains the points (−26, −37)(−26, −37) and (−32, −61)(−32, −61) . What is the slope of the line in simplified form?

Rus_ich [418]

Slope = (y2 - y1)/(x2 - x1) = (-61 - (-37))/(-32 - (-26)) = (-61 + 37)/(-32 + 26) = -24/-6 = 4

Therefore, slope = 4

Which of the following is equal to (2x/3 - 7) + 7

diamong [38]

<span>The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.</span>

If sec theta = - √30 / 3, find cos theta.<br> if sin(-theta) = -0.97, find cos (π/2 - theta).

Cloud [144]

Step-by-step explanation:

$\cos \theta = \frac{1}{ \sec\theta } = - \frac{3}{ \sqrt{30} } = - \frac{3 \sqrt{30} }{30} = - \frac{ \sqrt{30} }{10}$

$\cos( \frac{\pi}{2} - \theta )= \cos \frac{\pi}{2} \cos \theta + \sin \frac{\pi}{2} \sin \theta$

Note that

$\sin( - \theta) = - \sin \theta$

$\cos \frac{\pi}{2} = 0 \: \: \: \: \: \sin \frac{\pi}{2} = 1$

Therefore,

$\cos( \frac{\pi}{2} - \theta ) = 0.97$
