The first time a census was taken in Michele Corners, the population was 1772. Each year after that, the population was about 9%

higher than it was the previous year.
Sketch the graph that represents the situation. Let x represent the number of years since the first census was taken.

What are the coordinates of the point that contains the ­y-intercept?

We are given

The first time a census was taken in Michele Corners, the population was 1772

so, initial population =1772

so, P=1772

Each year after that, the population was about 9% higher than it was the previous year

so, r=9%

r=0.09

now, we can use formula

y=P(1+r)^{x}

y is population after x years

x represent the number of years since the first census was taken

so, we get equation as

y=1772(1+0.09)^{x}

y=1772(1.09)^{x}

y-intercept:

so, we can plug x=0 to get y-intercept

y=1772(1.09)^{0}

y=1772...........Answer

A new shopping mall is gaining in popularity every day since it open the number of shoppers is 20% more than the numbers of shop
erastovalidia [21]

Answer: the number of shoppers on the first day is 125

Step-by-step explanation:

The number of shoppers is 20% more than the numbers of shoppers the day before. It means that the number of shoppers is increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as

Sn = (ar^n - 1)/(r - 1)

Where

n represents the number of term in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

r = 1 + 20/100 = 1.2

n = 4(first 4 days)

S4 = 671

Therefore, the expression for the first 4 days is

671 = (a × 1.2^(4) - 1)/1.2 - 1

671 = (a × 1.2^(4) - 1)/0.2

671 = 1.0736a/0.2

671 = 5.368a

a = 671/5.368

a = 125

The formula for the perimeter, P, of a rectangle is P = 2L + 2w, where L is the length and W is th width sovle the formula for t
vichka [17]

                                 P  =  2L + 2w

Subtract  2L
from each side:          P - 2L  =  2w

Divide each side
by  2 :                        (P - 2L) / 2  =  w

You could also write it as      (P/2  -  L)  =  w
Both answers are the same.
