Question

Prompt

r (t) = 55 t - 2 t^{2}

. The function

r

is defined by the given equation. The function

s

is defined by

s (t) = r (t) + 1

. Which expression represents the maximum value of

s (t)

1 + (\frac{55}{2})^{2}

1 + 2 (\frac{55}{4})^{2}

1 - 2 (\frac{55}{4})^{2}

1 - (\frac{55}{2})^{2}
