dezoksy [38]

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.

Find the angle x in this triangle
Romashka-Z-Leto [24]

Answer:

x = 36

Step-by-step explanation:

<em>A triangle has 180°</em>.

That <em>third angle is 360 - 8x</em>.

So the equation is: <em>180 = 2x + x + 360 - 8x</em>.

Simplify: 180 = -5x + 360

Add/Subtract: 5x = 180

Divide: x = 36.
