Answer:
The year in which the population of Los Angeles reached 2.6 million is 1965.
Step-by-step explanation:
We are given the approximate population y (in millions) of Los Angeles between 1950 and 2000 is given by:
![y = 0.0000113x^3-0.000922x^2 +0.0538x + 1.97](https://tex.z-dn.net/?f=y%20%3D%200.0000113x%5E3-0.000922x%5E2%20%2B0.0538x%20%2B%201.97)
y = Population(in millions)
We are supposed to find the year in which the population of Los Angeles reached 2.6 million.
Substitute y = 2.6
![2.6 = 0.0000113x^3-0.000922x^2 +0.0538x + 1.97\\2.6-1.97=0.0000113x^3-0.000922x^2 +0.0538x\\0.63=0.0000113x^3-0.000922x^2 +0.0538x](https://tex.z-dn.net/?f=2.6%20%3D%200.0000113x%5E3-0.000922x%5E2%20%2B0.0538x%20%2B%201.97%5C%5C2.6-1.97%3D0.0000113x%5E3-0.000922x%5E2%20%2B0.0538x%5C%5C0.63%3D0.0000113x%5E3-0.000922x%5E2%20%2B0.0538x)
The real solution is x=14.77≈15
We are given that 0 corresponds to 1950.
So, 15 corresponds to 1965
Hence the year in which the population of Los Angeles reached 2.6 million is 1965.
91x0.5=4.5. You’d get a f
Uhmmmm is there a picture of the problem i’m confused
