The graph equation
From the graph, we have:


The slope of the graph is:




So, the graph equation is:




In standard form, we have:

$7.50 per hour times <span>32.5 hours equals $243.75
$ 7.50 per hour
x 32.5 worked hours
----------
$243.75 is her check</span>
The two numbers are (7+ sqrt(65))/2 and (7- sqrt(65))/2
(7+ sqrt(65))/2+ (7- sqrt(65))/2= 7
(7+ sqrt(65))/2* (7- sqrt(65))/2)= -4.

Answer:
So the decay percentage rate is of 70.8%
Step-by-step explanation:
An exponentil function has the following format:

In which c is a constant.
If a>1, we have that a = 1 + r and r is the growth rate.
If a<1, we have that a = 1 - r and r is the decay rate.
In this problem:
a = 0.292
A is lesser than 1, so r is the decay rate.
1 - r = 0.292
r = 1 - 0.292
r = 0.708
So the decay percentage rate is of 70.8%
