Mekhanik [1.2K]2 years ago
4 0

Answer:

y = 3x² + 15x + 12

Step-by-step explanation:

A quadratic function in standard form is

y = ax² + bx + c ( a ≠ 0 )

Given

y = 3(x + 4)(x + 1) ← expand the factors using FOIL

  = 3(x² + 5x + 4) ← distribute parenthesis by 3

  = 3x² + 15x + 12

The most recent census for a city indicated that there were 919,716 residents. The population of the city is expected to increas
OLEGan [10]

Answer:

1,474,951.

Step-by-step explanation:

Given a population that increases by a constant percentage, we can model the population's growth using the exponential model.

P(t)=P_o(1+r)^t,$ where \left\{\begin{array}{lll}P_o=$Initial Population\\r$=Growth rate\\$t=time (in years)\end{array}\right\\P_o=919,716\\r=3.7\%=0.037\\$t=13 years

Therefore, the population of the city in 13 years time will be:

P(t)=919,716(1+0.037)^{13}\\\\=919,716(1.037)^{13}\\\\=1,474,950.9\\\\\approx 1,474,951

The population be at that time will be approximately 1,474,951.
