The population of ls vegas nevada has been increasing at an annual rate of 7.0%. if the population of las vegas was 478,434 in 1999, predict its population in 2015

The answer is:

The population in 2015 will be 1,412,415.

Since from the statement we know that the population is increasing, we know that we are working with an exponential growth problem.

We can calculate the exponential growth using the following equation:

Where,

P, is the population after t (years, months, days or hours)

Start Population, is the starting population.

Growth percent, is the percent of growth

t, is the time elapsed (years, months, days or hours)

So, we are given the following information:

Now, substituting and calculating, we have:

Hence, the population in 2015 will be 1,412,415.

Have a nice day!

i belive those are the ones that are under 90 degreese.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
