Rom4ik [11]

Answer:

Step-by-step explanation:

We are required to evaluate:

0.1m+8-12n

When $m=30, n=\frac{1}{4}$

Substituting these values into the expression, we have:

$0.1m+8-12n=0.1(30)+8-12(\frac{1}{4})\\=3+8-\frac{12}{4}\\=3+8-3\\=8$

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,

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

Which of the following are the correct properties of slope? Check all that apply.

Grace [21]

It's up to you what you chose for A and or B because 0 slope of a line is for a flat horizontal line and an undefined slope is for a flat vertical line
With this information you should chose D regardless but that's also up to you I would though and E is correct.
