We know that

Each pie was cut into six slices
there are a total of 48 pieces-----> divide by six to find the number of pies
48/6----> 8 pies

Two of the pies will be served to members of the department as courtesy
so
subtract 2 to the total of pies to find the pies available for sale
whole pies available for sale=8-2-----> 6 pies

Hello,

A) $a=e^ \frac{t}{2} \\\\

v(t)=\int\ a\ dt=\int\ e^ \frac{t}{2}\ dt=2*e^ \frac{t}{2}+C\\\\v(0)=-4\\
 2*e^ \frac{0}{2}+C=-4\\
 C=-6\\\\

\boxed{v(t)= 2*e^ \frac{0}{2}-6}\\\\



$

B)
$2*e^ \frac{t}{2}-6=0\\\\

e^ \frac{t}{2}=3\\\\

t=2*ln(3)\approx{2,19722...}\\

$

C)

$x(t)=\int_0^6(2*e^ \frac{t}{2}-6})\ dt=\left[4*e^ \frac{t}{2}-6t\right]_0^6\\\\ =e^3-36-4=4e^3-40\approx{40.3421...}\\\\$
