Answer:
y= 1200(0.92)^x
Step-by-step explanation:
Given data
Cost price= $1200
Rate of decrease= 8%
Let the time be x
The expression that describes an exponential function is
y= ab^x
for decrease b= 1-r
y= 1200(1-0.08)^x
y= 1200(0.92)^x
Hence the expression is
y= 1200(0.92)^x
It is the multiplying factor for the whole equation if that makes sense.
Answer:
Step-by-step explanation:
To find the quotient, we first need to know what quotient means.
Quotient is the solution to division problems.
So here is how we have to do this, first we identify our fractions:
Next, we must turn the fraction we are dividing by into a reciprocate:
Now we have
Next, we multiply!:
