Grace is collecting dimes and quarters in a jar. She has collected \( \$ 7.50 \) so far and has \( d \) dimes and \( q \) quarters. The relationship between the number of dimes and quarters and the amount of money Grace has in dollars in the jar can be represented by the equation \( 0.1 d+0.25 q=7.50 \). Select all th ordered pairs \( (d, q) \) that are solutions to this equation.

4. Determina los lados de la figura luego halla el perimetro \( A=y^{2}-27 y+50 \)

7. Si \( p(x)=2 x^{2}-8 x-24 \quad \) ¿Cuál será un cero del polinomio?

8) Función cuática. \( \begin{array}{ll}f(x)=x^{4}-4 x^{2}+z & f(x)=-x^{4}+2 x^{2} \\ \frac{x y}{-2} & \frac{x y}{-2} \\ -1 & -1 \\ 0 & 0 \\ 1 & 1 \\ 2 & 2\end{array} \)

\( 4 \sin ^{2}(x)+6 \sin (x)+2=0 \) \( x=\square \) help (angles)
