5. -2 = p - 1 Help me pleaseee

Mathematics

Assuming you are trying to find the value of p:

You would add 1 to each side to make the p alone

-2 =p - 1
+1 +1

-1 = p


To check, you can put p in the original equation

-2 = -1 - 1

-2 = -2 which means this is correct


Hope this helps! If you can, please give brainlist! :)

The circumference of a circle is 28 pi meters. What is its radius
astraxan [27]

Circumference's formula is: 2πr

Since π is not added in the total (as it is 28π), just divide 28 with 2 to get r

28/2 = 14

The radius is 14

hope this helps

Use the Chain Rule to find the indicated partial derivatives. z = x^4 + xy^3, x = uv^4 + w^3, y = u + ve^w Find : ∂z/∂u , ∂z/∂v
k0ka [10]

I'll use subscript notation for brevity, i.e. \frac{\partial f}{\partial x}=f_x.

By the chain rule,

z_u=z_xx_u+z_yy_u

z_v=z_xx_v+z_yy_v

z_w=z_xx_w+z_yy_w

We have

z=x^4+xy^3\implies\begin{cases}z_x=4x^3+y^3\\z_y=3xy^2\end{cases}

and

\begin{cases}x=uv^4+w^3\\y=u+ve^w\end{cases}\implies\begin{cases}x_u=v^4\\x_v=4uv^3\\x_w=3w^2\\y_u=1\\y_v=e^w\\y_w=ve^w\end{cases}

When u=1,v=1,w=0, we have

\begin{cases}x(1,1,0)=1\\y(1,1,0)=2\end{cases}\implies\begin{cases}z_x(1,2)=12\\z_y(1,2)=12\end{cases}

and the partial derivatives take on values of

\begin{cases}x_u(1,1,0)=1\\x_v(1,1,0)=4\\x_w(1,1,0)=0\\y_u(1,1,0)=1\\y_v(1,1,0)=1\\y_w(1,1,0)=1\end{cases}

So we end up with

\boxed{\begin{cases}z_u(1,1,0)=24\\z_v(1,1,0)=60\\z_w(1,1,0)=12\end{cases}}

Find the point slope equation for the line that passes through the points (2,1) and (-2,5). use the first point in your equation
Delicious77 [7]

Answer:

y - 1 = -(x - 2)

Step-by-step explanation:

y - y1 = m(x - x1)

m = (5-1)/(-2-2) = 4/-4 = -1

Using any one coordinate, construct

y - y1 = m(x - x1)

y - 1 = -1(x - 2)
