-7 -5 / 4 -2 / -12/2

-12/2 = -6

Slope: -6x

5 = 2(-6) + b

5 = -12 + b 

-12 + 17 = 5 

Slope intercept Form: y = -6x + 17

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume

melisa1 [442]

Answer:

1st one is 1/3. The 2nd one is πr²h. The Last one is 1/3πr²h.

Step-by-step explanation:

The formula for the volume of a cone with the same base and height will always be 1/3 the volume of a cylinder. The exact formula for the volume of a cylinder is just πr²h. So, if a cone is 1/3 of that, it will result in 1/3πr²h.

Can someone answer #9

In-s [12.5K]

Solution:

First i'm going to divide the graph into 3 parts. Linear, Quadratic and Horizontal graph.

Linear:

$Slope=\frac{-2-0}{-4-(-2)}=1\\y=m(x-xo)+yo\\y=1x-(-2)+(-4)\\y=x-2 , x\leq-1$

Quadratic:

$f(x) = a(x-h)^{2} + k\\f(x)=(x-2)^{2}-7,-1\leq x\geq 6$

Horizontal:

$f(x)=7,x\geq 6$

Answer:

$f(x)=x-2 , x\leq-1\\f(x)=(x-2)^{2}-7,-1\leq x\geq 6\\f(x)=7,x\geq 6$

Hope this was helpful.
