Solve.The maximum number of volts, E, that can be placed across a resistor is given by the formula 
where P is the number of watts of power that the resistor can absorb and R is the resistance of the resistor in ohms. Solve this equation for R. Use the result to determine the resistance of a resistor if P is 2 watts and E is 30 volts.
A. R = 
B. R = E2P
C. R = E2P2
D. R = 
Write the equation of the graph after the indicated transformation(s). The graph of y = x2 is shifted 2 units to the left. This graph is then vertically stretched by a factor of 6 and reflected across the x-axis. Finally, the graph is shifted 8 units downward.
A. y = -6(x + 8)2 - 2 B. y = -6(x - 2)2 + 8 C. y = -6(x + 2)2 - 8 D. y = -6(x - 2)2 - 8
