Fine the exact distance between the line 6x-y=-3 and the point (6,2). Show your work. Explain your answer.
AVprozaik [17]

Answer:

\sqrt{37} units

Step-by-step explanation:

If we draw a perpendicular from point (6,2) on the line 6x - y = - 3, then we have to find the length of the perpendicular.  

We know the formula of length of perpendicular from a point (x_{1}, y_{1} ) to the straight line ax + by + c = 0 is given by  

\frac{|ax_{1} + by_{1} +c |}{\sqrt{a^{2}+b^{2}}}

Therefore, in our case the perpendicular distance is  

\frac{|6(6)-2+3|}{\sqrt{6^{2} +(-1)^{2} } } = \frac{37}{\sqrt{37} } = \sqrt{37}  units. (Answer)

H=-5 and w=2, work out the value of 4h-3w
olganol [36]
You would simply have to plug in, or substitute, the given values in the equations.

So, H=-5, W=2 and the problem is 4h-3w

To plug them in, your new equation would be 4(-5)-3(2) and simplify. So it becomes -20-6 which = -26. 

And -26 would be your answer.

If you have 2 shirts 2 jackets and 2 skirts how many outfits can you make
zvonat [6]
Hello!

If you assume that with each outfit you must use at least one of each shirt, jacket, and skirt, you have a 1/2 chance of selecting one of each. Since it is a compound event (an outfit), you will multiply each singular probability (shirt, jacket, skirt) together.

\frac{1}{2}·\frac{1}{2}·\frac{1}{2}=\frac{1}{8}

You can make eight different outfits.

I hope this helps!
