iragen [17]

Answer:

175 means the city's population is 175 thousands in 2010.

Step-by-step explanation:

The model below gives the projection of the city's population , P, in thousands, with respect to time, t, in years, where 2010 corresponds to t=0.

The given equation is

$P=175+\dfrac{11}{2}t$

We need to interpret 175 for the given model.

Substitute t=0 in the above equation.

$P=175+\dfrac{11}{2}(0)$

$P=175$

At t=0 the value of P is 175 it means the city's population is 175 thousands in 2010.
