QUESTÃo 09 - São dadas duas circunferências de raios \( r_{1}=15 \mathrm{~cm} \) e \( r_{2}=\mathbf{9} \mathrm{cm} \). Sendo \( d \) a distância entre os centros dessas circunferências, qual é o valor de d para que essas circunferências sejam tangentes interiores? Resolução:

coordinate grid below. Find the coordinates of a fourth point o that the four points form the vertice of a rectangle.

Si \( P=(1,-1) \) y \( Q=(\sqrt{2},-1) \), la magnitud del vector \( \overrightarrow{P Q} \) es

Draw a graph of the line that contains the given point and has the given slope. \( (0,1) ; m=-3 \)

Graph the line containing the point \( P \) and having slope \( m \). \( P=(-6,3) ; m=0 \)

The midpoint between two points is \( \{1,5\rangle \). One of those points is \( \{8,3\rangle \), find the other.
