a piece of lumber leans against a wall. the top of this 40 foot piece of lumber touches a point on the wall that is 36 feet abov
nignag [31]
So first find the distance from the bottom of the lumber to the wood
40^2= 36^2+X^2
X=304^1/2. Or the sqaure root of 304

The you use the sin equation

Sin90*\40= sin(unknown angle)/304^1/2
Sinx(x) = ((304^1/2)xsin(90))/40
X=arcsin((304^1/2)xsin(90))/40

What is the slope of the line through (–4, 3) and (5, 3)?
miskamm [114]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =3\\y_{1} =3\\x_{2} =5\\x_{1} =-4

^^^Plug these numbers into the formula for slope...

\frac{3-3}{5 - (-4)}

\frac{0}{9}

0

^^^This is your slope

If your slope is zero that means that the graph will be horizontal

Hope this helped!
