The period T of a pendulum is the time it takes to move from one side to the other and back. A formula for the period is Tequals2 pi StartRoot StartFraction Upper L Over 32 EndFraction EndRoot where T is in seconds and L is in feet. Use 3.14 for pi. Find the period of a pendulum of length 18 feet. The period of a pendulum of length 18 feet is nothing seconds. (Type a decimal.)

Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which transformations should you perform. a) reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up. b) reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up. c) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up. d) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.
