Answer:

A. 8

Step-by-step explanation:

C(8,1) means number of ways of choosing 1 element out of 8

That is it is a combination.

We know that the formula for C(n,r) is:

      \dfrac{factorialn}{factorialr\times factorial(n-r)}

C(8,1)=  \dfrac{factorial8}{factorial1\times factorial(8-1)}

        =  \dfrac{factorial8}{factorial1\times factorial7}

        =  \dfrac{8\times factorial7}{factorial7}   (since, factorial1=1)

        = 8

Hence, correct option is:

A. 8

Step-by-step explanation:

● formulas of valume = πr²h

  • 22/7×12×12×38•4 ft
  • 3•14×144×38•4 ft
  • 452•16×38•4 ft
  • 17362•944 ft³

● now nearest to the number

 find the equation of the line that is parallel to the line Y equals 3X -6 and passes through the points (1 -8). Write the equa
AlladinOne [14]
<h3>hello!</h3>

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

Parallel lines have the same slope.

So if the given line has a slope of 3, then the line parallel to it has the same slope (3)

Now, let's write the equation of the line in Point-Slope Form.

Remember, point-slope form looks like so:-

\bigstar{\underline{\boxed{\pmb{y-y1=m(x-x1)}}}

Where

y₁ is the y-coordinate of the point that the line passes through

m is the slope

x₁ is the x-coordinate of the point that the line passes through

In this case,

y₁ is equal to -8

m is equal to 3

x₁ is equal to 1

Plug in the values:

\longrightarrow\sf{y-(-8)=3(x-1)}

Simplify:

\longrightarrow\sf{y+8=3(x-1)}

and we're done!

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

<h3>note:-</h3>

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
