The quadratic function f (x) = - 45x2 + 350x + 1,590 models the population of a city where x represents the number of years sinc
1 answer:
Answer: 2,215,000
Step-by-step explanation:
Given: The quadratic function models the population of a city where x represents the number of years since 2005.
To Find: population of the city in 2010
We need to put x= 2010-2005 = 5
Hence, the estimated population of the city in 201 = 2215 thousands or 2,215,000 .

Answer:
A) The set builder notation is: {n | n∈Z, 1≤n≤7}.
B) The set builder notation is:
C) The set builder notation is:
D) The set builder notation can be:
Step-by-step explanation:
Consider the provided information,
We need to use set-builder notation to describe the following sets.
(a) {1,2,3,4,5,6,7}
Here, the number are integer starting from 1 to 7.
Thus, the set builder notation is: {n | n∈Z, 1≤n≤7}.
(b) {1, 10, 100, 1000, 10000}
The above set can be written as:
Thus, the set builder notation is:
(c) {1, 1/2, 1/3, 1/4, 1/5, ...}
Here the numerator is 1 for each term but denominator is natural number.
Thus, the set builder notation is:
(d) {0}
The set builder notation can be:
Answer:
Step-by-step explanation:
1. Use this to find the average rate of change
2. Average rate of change =
3. and
(To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))
4. Replace -4 to f(8) and -10 to f(6)
5. So it will look like
6. Solve
