Answer:
I think it's 2566.8 if 4.6 is taken out of the account annually. I think that is what it is asking.. I'm only 13 so I'm not great at these yet but it should be right because I'm really good at math

Answer:
Cost price of the fan is  .
.
Step-by-step explanation:
Given: A man sold a fan for   . He incurred a loss of
. He incurred a loss of  .
.
To find: The cost price of the fan
Solution: 
We have,
Selling price, S.P.,  of the fan 
Loss 
We know that 
Now let the C.P. of the fan be 
So, 





Hence, the cost price of the fan is  .
.

Answer:
a) 8, multiplicity 2; 8, multiplicity 3
Step-by-step explanation:
Remember that a is a zero of the polynomial f(x) if f(a)=0 and has multiplicity n if the termn (x-a) is n times in the factorization of f(x).
We have that 

Observe that 
1. 
and (x+8) appear two times in the factorization of f(x). Then -8 is a zero of f(x) with multiplicity 2.
2. 
and and (x - 8) appear three times in the factorization of f(x). Then 8 is a zero of f(x) with multiplicity 3.
Since f(x) has degree 5 and the sum of the multiplicities is 5 then f(x) hasn't more zeros.
 
        
             
        
        
        
By trial and error, I got it first correctly. The granola
bars cost $1 each and the yogurt is $.50 per cup. By plugging this in to each
equation, you'll see that 12 granola bars equals $12, and 7 cups of yogurt
equals $3.50, for a total of $15.50. The second account would produce $6 +
$5.50, which equals $11.50.
