Final answer:
The expression for the population of San Jose in the year 2000 is approximately 1,270,719.34 people.
Step-by-step explanation:
To find the expression for the population of San Jose in the year 2000, we can use the formula P(1) = Po * (1 + r)n, where Po is the initial population, r is the growth rate, and n is the number of years.
The initial population of San Jose in 1990 was 782,000, and the growth rate is 5% per year.
Substituting these values into the formula, we get:
P(1) = 782,000 * (1 + 0.05)^10 = 782,000 * (1.05)^10 = 782,000 * 1.628895 = 1,270,719.34
Therefore, the expression for the population of San Jose in the year 2000 is approximately 1,270,719.34 people.
