try and see if it =0
Step-by-step explanation:
This deals with factoring multi-variable polynomials.
Answer:
$39.2
Step-by-step explanation:
The sale price will be 20% of $49 subtracted from $49
That’s
20% /100% x $49
0.2 x $49
$9.8
Sale price = $49 - $9.8
= $39.2
The sale price is $39.2
The expression y = 660(0.902)ˣ represents a decay , the rate of decrease is 9.8% .
In the question ,
it is given that ,
the the exponential function is y = 660(0.902)ˣ
we need to determine that , the equation represents a growth or decay .
0.902 is the variable that will determine a growth or decay .
Since, 0.902 is less than 1 , so it represents a decay function .
To find the rate we subtract 0.902 from 1
= 1 - 0.902
= 0.098
= 9.8% decrease rate
Therefore , The expression y = 660(0.902)ˣ represents a decay , the rate of decrease is 9.8% .
The given question is incomplete , the complete question is
Identify if it's Growth or Decay , and determine the percentage rate of increase or decrease , the function is y = 660(0.902)ˣ ?
