Which of the following are considered skew lines? 1.cone 2. Prism 3. Cylinder 4.cube

Name the slope and one point that is on the line

Alekssandra [29.7K]

Answer: Choice A

m = undefined

point (-2,5)

==================================================

Explanation:

The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)

Another point on this line is (-2,5) since this also has x coordinate -2.

------------------

All vertical lines have undefined slope.

Let's pick two points such as (-2,0) and (-2,1) and find the slope through them

m = (y2-y1)/(x2-x1)

m = (1-0)/(-2-(-2))

m = (1-0)/(-2+2)

m = 1/0

m = undefined, since we cannot divide by zero.

Can someone please solve these problems for me if you could do step by step that would rlly help me this is due Feb 14, 2021 ple

dsp73

Answer:

7. about 41.8 degrees or 0.72972 radians (used $sin^{-1} (\frac{4}{6} )$ , because the given leg is opposite from the angle)

8. about 50.4 degrees or 0.87946 radians (used $tan^{-1} (\frac{29}{24} )$ )

9. about 12.8 degrees or 0.224 radians (used $sin^{-1} (\frac{12}{54} )$ )

10. about 51.3 degrees or 0.8957 radians (used $cos^{-1} (\frac{25}{40} )$ , given leg is opposite from angle)

Step-by-step explanation:

S.O.H.--C.A.H.--T.O.A

sine = opposite (to angle)/hypotenuse

cosine = adjacent (to angle)/hypotenuse

tangent = opposite (to angle)/adjacent (to angle)

I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!

There are 7 Democrats and 6 Republicans on a local city council. A planning committee of 6 for affordable housing needs to be

Brut [27]

Answer:

The probability is $0.383$ .

Step-by-step explanation:

There are 7 democrats and 6 republicans

Number of ways in which 4 democrats and 2 republicans can be selected= ${}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}$

Number of ways in which 5 democrats and 1 republican can be selected= ${}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}$

Number of ways in which 6 democrats can be selected = ${}^{7}{{C}_{6}}$

So, favourable outcomes are ${}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}$

Total possible outcomes = ${}^{13}{{C}_{6}}$

Now, probability= $\frac{Favourable}{Possible}=\frac{{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}}{{}^{13}{{C}_{6}}}=0.383$
