A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the number of shoppers is 10

Iteru [2.4K]

Answer:

$1,139\ shoppers$

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

$y=a(b)^{x}$

where

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate in decimal form

b=(1+r)

In this problem we have

x ----> the number of days

y ----> the number of shoppers

a=120

r=10%=10/100=0.10

b=1+0.10=1.10

substitute the values

$y=120(1.10)^{x}$

First day

$y=120$

Second day

For x=1 day

substitute the value of x in the equation and solve for y

$y=120(1.10)^{1}=132$

Third day

For x=2 days

$y=120(1.10)^{2}=145$

Fourth day

For x=3 days

$y=120(1.10)^{3}=160$

Fifth day

For x=4 days

$y=120(1.10)^{4}=176$

Sixth day

For x=5 days

$y=120(1.10)^{5}=193$

Seventh day

For x=6 days

$y=120(1.10)^{6}=213$

Adds the numbers

$120+132+145+160+176+193+213=1,139$

If the endpoints of `bar(AB)` have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of `bar(AB)`?

alina1380 [7]

To solve this problem you must apply the proccedure shown below:

1. You have the following points given in the problem above:

$A(9,8)\\ B(-1,-2)$

2. To find the midpoint, you must apply the formula that is used for calculate it. This is:

$m=(\frac{x1+x2}{2}, \frac{y1+y2}{2} )$

Where:

$x1=9\\ x2=-1\\ y1=8\\ y2=-2$

3. Now, you must substitute these values into the formula for calculate the midpoint, as following:

$m=(\frac{9+(-1)}{2} ,\frac{8+(-2)}{2} )\\ m=(4,3)$

Therefore, the answer is: $m=(4,3)$
