How much does it cost to get a TANKED fish tank?

Sets \( B \) and \( D \) are subsets of the universal set \( U \). These sets are defined as follows. \[ \begin{array}{l}U=\{f, k, r, x, z\} \\ B=\{f, k, x\} \\ D=\{f, r, x\}\end{array} \] Find the following sets. Write your answer in roster form or as \( \varnothing \). (a) \( B \cap D^{\prime}=\square \)

Sets \( A \) and \( B \) are subsets of the universal set \( U \). These sets are defined as follows. \[ \begin{array}{l}U=\{k, m, q, s, y, z\} \\ A=\{q, z\} \\ B=\{q, y\}\end{array} \] Find the following sets. Write your answer in roster form or as \( \varnothing \). (a) \( A \cup B^{\prime}=\square \) (b) \( A^{\prime} \cap B^{\prime}=\square \)

The input voltage to the \( R C \) circuit is given as \( \boldsymbol{x}(t)=t e^{-t / R C} u(t) \) and impulse response of the circuit is given by \( \mathbf{h}(\mathbf{t})=\frac{\mathbf{1}}{\mathbf{R C}} e^{-t / R C} \mathbf{u}(t) \) Find the output \( y(t) \).
