Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

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

First day

Second day
For x=1 day
substitute the value of x in the equation and solve for y

Third day
For x=2 days

Fourth day
For x=3 days

Fifth day
For x=4 days

Sixth day
For x=5 days

Seventh day
For x=6 days

Adds the numbers

Use the metric relations,
AC*CD=BC^2
=>
5*CD=9^2
solve for CD
CD=9*9/5=16.2
Its the first one. I typed them all in my graphing calculator to check
Answer:
(2,-9)
Step-by-step explanation:
A reflection around the x-axis implies keeping the x-coordinate as it its (no change in its numerical value), while using the exact opposite of the numerical value of the y coordinate.
In our case then:
X coordinate unaltered = 2 stays as 2
Y coordinate opposite of the original value: 9 changes to "-9"
Therefore the coordinates of point A' are: (2,-9)
