The population of a certain inner-city area is estimated to be declining according to the model P(t)=385,000e−0.022t, where t is the number of years from the present. What does this model predict the population will be in 9 years? Round to the nearest person.

This model predicts that population will be 315,842 in 9 years.

Step-by-step explanation:

Let the population of the city be represented by the function , where is the number of years from the present. The negative exponent means that such city is expected to experiment a sustained decrease. The predicted population in 9 years is determined by evaluating the function at :

This model predicts that population will be 315,842 in 9 years.

1. 3

2. 4

3. 1

hope this ! have a great day.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
