A polynomial is given by $t=4\mathrm{.}5s^2+7\mathrm{.}5s+5\mathrm{.}0.$ Read $s$ from input as a float and compute $t$ using the polynomial.

Ex: If the input is $1\mathrm{.}8,$ then the output is:

$33\mathrm{.}080$

Note: $s^2$ can be computed using $*$

$1s=1\mathrm{.}8$

$2t=4\mathrm{.}5s^{{?}^{{?}^{?}}}(2)+7\mathrm{.}5s+5\mathrm{.}0$

$3$ print $(f^{\text{'}}\{t$:$\mathrm{.}3f{\}}^{\text{'}})$
