the population of a town grows at the rate of 3 percent each year in 2010, the town had a population of 250000. what is the popu

Ulleksa [173]

Answer:

335,979 people (in Year 2020)

Step-by-step explanation:

Initial Population (Year 2010) = 250,000

Rate of Growth = 3% = 3/100 = 0.03

We want the population of the town in Year 2020 (at this rate). That is 10 years from now.

The formula for compound growth is:

$F=P(1+r)^t$

Where

F is the future value (in year 2020)

P is the present value (250,000)

r is the rate of increase per year (0.03)

t is the time in years (t = 10)

Lets substitute and find the value:

$F=P(1+r)^t\\F=250,000(1+0.03)^{10}\\F=250,000(1.03)^{10}\\F=335979.09$

Rounded, that would be:

335,979 people (in Year 2020)

What are the cons of graphing, elimination, and substitution?

rosijanka [135]

GRAPHING CONS

1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.

2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.

3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution

SUBSTITUTION CONS

1) Becomes tedious if a system has too many equations or variables

ELIMINATION PROS/CONS

1) basically same as substitution

Multiple choice can someone please answer please

Furkat [3]

Answer:

n = 6

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

$\frac{GH}{QR}$ = $\frac{FH}{PR}$ , substitute values

$\frac{n}{9}$ = $\frac{4}{6}$ ( cross- multiply )

6n = 36 ( divide both sides by 6 )

n = 6
