Lesson 14: What Do You Know About Polynomials? Cool Down: How Would You Factor? A polynomial \( D(x)=3 x^{3}-2 x^{2}-15 x+14 \) has known factors \( (x-2) \) and \( (x-1) \). Would you use a diagram, long division, or some other method to rewrite the expression for D in factored form? Explain your reasoning.

Using the definition, calculate the derivative of the function. Then find the values of the derivative as specified. \( g(t)=\frac{9}{t^{4}} ; g^{\prime}(-4), g^{\prime}(2), g^{\prime}(\sqrt{5}) \)

\( 4 m x^{2}+2 x-(3 m-2)=0 \) 4 Consider the equation

Un rettangolo ha la base che misura 3.4 dm taltezza e i \( \frac{3}{4} \) della base Calcola il perimetro del rettangolo in centimetri.

2) \( \left(x^{5}+2 x+4 x\right)=\left(-x^{6}+5 x\right)^{2} \)

Evaluate the expression \( \sin ^{-1}\left(\cos \left(\frac{7 \pi}{6}\right)\right) \) . Give your answer as an exact value
