What does changing the "k" variable do to the graph of a quadratic?

I’ll be assuming you meant k as in
the a in a quadratic equation:

ax^2 + bx + c

kx^2 + bx + c.

In this case, the “k” will indicate whether the graph will be opening upwards to form a “u” shape or it opens downwards to form a “n” shape

When “k” is positive, the graph would open upwards and form a “u”.

If “k” is negative, the graph would open downwards and form a “n”.

Have a great day ahead!

Can someone help with problems fivethroughseven
frutty [35]

Answer:

5) 15120

6) 11880

7) 336

Step-by-step explanation:

The formula for permutation where mPn is m!/(m-n)!

Applying this to question 5, we get 9!/4!, which is 15120.

For question 6, we get 12!/8!, which is 11880.

For question 7, we get 8!/5!, which is 336.

Can somebody please help me with question b please?
snow_tiger [21]
\bf A=
\begin{bmatrix}
-2&0\\1&3
\end{bmatrix}\qquad B=
\begin{bmatrix}
1&0&3\\-1&3&0
\end{bmatrix}\\\\
-----------------------------\\\\
AB=
\begin{bmatrix}
(-2\cdot 1)+(0\cdot -1)&(-2\cdot 0)+(0\cdot 3)&(-2\cdot 3)+(0\cdot 0)\\\\
(1\cdot 1)+(3\cdot -1)&(1\cdot 0)+(3\cdot 3)&(1\cdot 3)+(3\cdot 0)
\end{bmatrix}

as you notice above, is the first-row components from A, multiplying all the columns subsequently on B, and you add the products of that row, that gives you one component on the AB matrix

in the one above, we end up with a 2x3 AB matrix

The length of a rectangle is three times its width of the perimeter of the rectangle is 40 yd find its length and width
schepotkina [342]

Answer:

Step-by-step explanation:

L= 3W

Perimeter = 2(l+w) = 40

 

2(3w+w) = 40

 

2*4w = 40

8w =40

w = 5

l = 3*5 = 15
