We're going to evaluate that from zero to 10. So we're going to evaluate it at 10 and subtract from that this thing evaluated at zero. So this is going to be, let me just factor out this part right over here. So it's going to be negative 13.84 over negative 0.173 times this evaluated at when t is 10. So e to the, if we multiply this times 10, this is negative 1.73. That's when I evaluated at 10. And from that, we want to subtract when this is evaluated at zero.
