\( \overline{S V} \) is the midsegment of the trapezoid \( Q R T U \). If \( T U=p, S V=-2 p+20 \), and \( Q R=3 p-8 \), what is the value of \( p ? \)

Rewrite the expression by factoring out \( (w+2) \) \( 7 w^{2}(w+2)-(w+2) \)

A server has 44 coneflowers and 32 violets. Four of the coneflowers thrown away because they are wilted. The server divides the rest of flowers equally into 8 centerpieces. How many flowers are in each centerpiece?

Cuál es la derivada de la siguiente función (2 puntos) * \( f(t)=e^{-2 t} \cos (4 t) ? \) \( -8 e^{-2 t} \operatorname{sen}(4 t) \) \( -2 e^{-2 t} \cos (4 t)-4 e^{-2 t} \operatorname{sen}(4 t) \) \( -2 e^{-2 t} \cos (4 t)+e^{-2 t} \operatorname{sen}(4 t) \) \( 4 e^{-2 t} \operatorname{sen}(4 t) \)
