The area of a circle increases at a rate of \( 5 \mathrm{~cm}^{2} / \mathrm{s} \). a. How fast is the radius changing when the radius is 6 cm ? b. How fast is the radius changing when the circumference is 1 cm ?

La solucion de la siguiente ecuación \[ x / 2+3(2 / 3-x)=6-3 x \] es \( x \) igual a: 018 0.34 0.3 0.27

b. 7 pies a \( m= \)

Follow the steps for graphing a rational function to graph the function \( H(x)=\frac{2 x-8}{16-x^{2}} \). If needed, first write the given function as a single rational expression. Then, factor the numerator and denominator of \( \mathrm{H}(\mathrm{x}) \). Select the correct choice and, if necessary, fill in the answer box to complete your choice. A. \( H(x)=\square \) (Type your answer in factored form. Do not simplify.) B. \( H(x) \) is already in factored form.

Factor the polynomial completely. If the polynomial is not factorable, select prime. \[ \begin{array}{l}8 m^{3}+27 n^{3} \\ (2 m-3 n)\left(4 m^{2}+6 m n+9 n^{2}\right) \\ (2 m+3 n)\left(4 m^{2}-6 m n+9 n^{2}\right) \\ (3 m-2 n)\left(9 m^{2}+6 m n+4 n^{2}\right) \\ \text { Oprime } \\ (3 m+2 n)\left(9 m^{2}-6 m n+4 n^{2}\right)\end{array} \] Need Help?
