(1 point) Give the growth factor $b$, the starting value $a$, the growth rate $r$, and the value of $k$ when $Q$ is written in the form $Q = a e^{kt}$. If there is exponential decay, then your growth rate should be negative. For help entering logarithms, see help (logarithms)
$Q = 220 \cdot (1.898)^t$ has:
