If (G(t)=115-5t), what is (G(0))?
Advertisement
Answer and explanation
Correct answer: 115
To find the initial value, substitute \(t=0\): \(G(0)=115-5(0)=115\). Therefore, the correct answer is 115. The value 110 is obtained when \(t=1\), so it is a close but incorrect option. Exam tip: for \(G(0)\), the constant term gives the initial value.
