Answer:
I can't see the picture
Step-by-step explanation:
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 ?

Answer:
B. 9 - i
Step-by-step explanation:
Combine the real and imaginary parts in numbers 12 - 5i and -3 + 4i
(12 + 5i) + (-3 + 4i)
12 - 3 + (-5 + 4)i
Add 12 to -3. Add -5 to 4.
9 + (-i)
9 - i
The answer is $30.
We know discounted price of the shoes - $24.
We need to find out the original price of the shoes - x.
The discounted price is 80% of the original price (it is said that <span>shoes have been discounted 20%, so 100-20= 80%).
Let's set up a proportion. If $24 is 80%, how much is 100% (the original price):
$24 : 80% = x : 100 %
After crossing the products:
x = $24 * 100% / 80% = $30
Let's just check the result. After the discount of 20%, shoes will cost:
$30 - 20% = $30 - $30*(20/100) = $30 - $6 = $24.
</span><span>The original price of the shoes is $30.</span>
