10. What is the multiple zero and multiplicity of f(x) = (x - 3)(x - 3)(x + 5)? Multiple zero is -3; multiplicity is 2
Multiple zero is 5; multiplicity is 1
Multiple zero is -5; multiplicity is 1
Multiple zero is 3; multiplicity is 2

x=3, multiplicity of 2

x=-5, multiplicity of 1

Step-by-step explanation:

f(x) = (x - 3)(x - 3)(x + 5)

Rewriting

f(x) = (x - 3)^2(x + 5)

Setting equal to zero

0 =  (x - 3)^2(x + 5)

Using the zero product property

(x-3)^2  = 0   x+5 = 0

x-3 = 0         x= -5

x=3             x-5

Since x-3 was squared, the multiplicity is 2

8

Step-by-step explanation:

Given

Jeweler has 36 inches of silver chain.

She needs 5 times that much to make some necklaces i.e

She needs 3 times that much amount to make some bracelets i.e.

Length of a silver chain =36 inches

Total chain required

Therefore he needs 8 chains to make necklace and bracelets
