Will give 15 points. Select all of the equations that will produce exponential decay. y = 1/2 (5)^x
y = (2)^x
y = (0.1)^x
y = 3(0.4)^x
y = 2( 1/4 )^x
y = (3)^x

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
