The population of a small town on January 1, 2005, was 7,200. On January 1, 2006, the population was 7,416. On January 1, 2007,

gogolik [260]

Answer:

Step-by-step explanation:

A tool for regression analysis shows the given population values fit an exponential curve better than they fit a line. The exponential function for the population can be written as approximately ...

p(x) = 6211.54(1.02998^x) . . . . . x is years after 2000

Then for x=11, the population is about ...

p(11) ≈ 8596.4

The closest answer choice is 8597.

Consider the graph that represents the following quadratic equation.

lutik1710 [3]

Answer:

Part 1) The graphs open downward

Part 2) The vertex is the point (-2,5)

Part 3) The axis of symmetry is x=-2

Step-by-step explanation:

step 1

we have

$y=-\frac{1}{3}(x+2)^2+5$

This is a vertical parabola open downward (because the leading coefficient is negative)

The vertex is a maximum

step 2

The quadratic equation is written in vertex form

$y=a(x-h)^2+k$

where

(h,k) is the vertex

In this problem

The vertex is the point (-2,5)

step 3

The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

The x-coordinate of the vertex is -2

therefore

The axis of symmetry is x=-2

Which of the following best describes the end behavior of y=x^2 -bx +c as x approaches either positive or negative infinity?

Tcecarenko [31]

As x approaches either positive or negative infinity, y will approach positive infinity.
This is because x^2 will grow large much quicker than b*x, so it has more importance. So when considering the limit, we can imagine that the equation looks like this:
y = x^2
This equation will go to infinity for x approaching both negative and positive infinity.
