To find \( (c \circ p)(t) \), we need to evaluate the function \( c(w) \) at \( w = p(t) \). Let's break this down step-by-step:
- Start with the function \( p(t) = -6t^2 + 500t \), which gives us the number of widgets produced after \( t \) hours.
- Next, we need to substitute this value into the function \( c(w) = 500 + 3.6w \).
Thus, we can calculate \( (c \circ p)(t) \):
\[ (c \circ p)(t) = c(p(t)) = c(-6t^2 + 500t) \]
Now, substitute \( p(t) \) into \( c(w) \):
\[ c(-6t^2 + 500t) = 500 + 3.6(-6t^2 + 500t) \]
Now distribute \( 3.6 \):
\[ = 500 + 3.6(-6t^2) + 3.6(500t) \] \[ = 500 - 21.6t^2 + 1800t \]
Now combine the constants:
\[ = 2300 + 1800t - 21.6t^2 \]
So,
\[ (c \circ p)(t) = -21.6t^2 + 1800t + 2300 \]
In summary, \( (c \circ p)(t) = -21.6t^2 + 1800t + 2300 \).
