Find $$$\frac{d}{dt} \left(t - 8\right)$$$.
Solution
The derivative of a sum/difference is the sum/difference of derivatives:
$${\color{red}\left(\frac{d}{dt} \left(t - 8\right)\right)} = {\color{red}\left(\frac{d}{dt} \left(t\right) - \frac{d}{dt} \left(8\right)\right)}$$Apply the power rule $$$\frac{d}{dt} \left(t^{n}\right) = n t^{n - 1}$$$ with $$$n = 1$$$, in other words, $$$\frac{d}{dt} \left(t\right) = 1$$$:
$${\color{red}\left(\frac{d}{dt} \left(t\right)\right)} - \frac{d}{dt} \left(8\right) = {\color{red}\left(1\right)} - \frac{d}{dt} \left(8\right)$$The derivative of a constant is $$$0$$$:
$$1 - {\color{red}\left(\frac{d}{dt} \left(8\right)\right)} = 1 - {\color{red}\left(0\right)}$$Thus, $$$\frac{d}{dt} \left(t - 8\right) = 1$$$.
Answer
$$$\frac{d}{dt} \left(t - 8\right) = 1$$$A
