Answer:
Cost price of the fan is .
Step-by-step explanation:
Given: A man sold a fan for . 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.
