**Partial Derivatives**

**Overview:**

We consider the function \( P(T, F) = e^{\sqrt{F}(1 + 4T)^{3/2}} \), which models the population of cells \( P \) as it depends on two key factors: the ambient temperature \( T \) (in degrees Celsius) and the availability of a liquid "food" \( F \) (in mL).

**Tasks:**

(a) Calculate \( P_T(2,4) \) and interpret its meaning, including proper units.

(b) Calculate \( P_F(2,4) \) and interpret its meaning, including proper units.

(c) Calculate \( P_{FF}(2,4) \) and interpret its meaning, including proper units.

(d) Calculate \( P_{FT}(2,4) \) and interpret its meaning, including proper units.

These tasks involve finding the partial derivatives of the function \( P(T, F) \). Partial derivatives help us understand how the population \( P \) changes with respect to either the ambient temperature \( T \) or the availability of liquid "food" \( F \), while keeping the other variable constant. Each derivative computation and its interpretation will provide insights into the sensitivity of the cell population to changes in temperature and food availability.
