The flash unit on a camera operates by storing charge on a capacitor and releasing it suddenly when the flash is set off. the following data describe the charge q remaining on the capacitor (measured in microcoulombs, µc) at time t (measured in seconds). t 0.00 0.02 0.04 0.06 0.08 0.10 q 100.01 85.84 73.67 63.23 54.27 46.58 (a) use a graphing calculator or computer to find an exponential model for the charge. (round your coefficients to three significant digits.)
