Answer:

C) 70°

Step-by-step explanation:

whole circle = 360°

inscribed angle theorem says that the measure of inscribed angle = 1/2 measure of intercepted arc

m∠DCB =1/2 m arc DB

46° = 1/2 m arc DB multiply both sides by 2

92° = m arc DB

m arc DC = 360° - 92° -128° = 140°

m ∠DBC = 1/2 m arc DC = 1/2*140° = 70°°

According to data from the U.S. Bureau of the Census, the approximate population y (in millions) of Los Angeles between 1950 and

dmitriy555 [2]

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:

$y = 0.0000113x^3-0.000922x^2 +0.0538x + 1.97$

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

$2.6 = 0.0000113x^3-0.000922x^2 +0.0538x + 1.97\\2.6-1.97=0.0000113x^3-0.000922x^2 +0.0538x\\0.63=0.0000113x^3-0.000922x^2 +0.0538x$

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.
