CCS8 Reason Inductively The table shows the mileage Karla drove on her trip. She drove for a total of 24 hours. Explain how to find her average speed. Then find the average speed.

Simplify the expression, if possible. \( \quad \ln e^{4} \)

Solve the equation. \[ \log _{5}(x+3)=2 \]

Civen the vector field \( \vec{u}\left(u_{x}, u_{y}, u_{z}\right)=x^{2} \vec{i}+z^{2} \vec{j}-x y^{3} \overrightarrow{k_{s}} \) colculate div \( \vec{u}=\vec{\nabla}=\frac{\partial u_{x}}{\partial x}+\frac{\partial u_{y}}{\partial y}+\frac{\partial u_{x}}{\partial z} \)

Find the normal vector to the plane \( 3 x+2 y+z+1=0 \)

Identify the two perpendicular planes.
