Answer:
The zeros of f(x) are: (x - 1), (x - 3) and (x - 8)
<em></em>
Step-by-step explanation:
Given
Required
Find all zeros of the f(x)
If then:
And is a factor
Divide f(x) by x - 8
Expand the numerator
Rewrite as:
Factorize
Expand
Factorize
Multiply both sides by x - 8
<em>Hence, the zeros of f(x) are: (x - 1), (x - 3) and (x - 8)</em>
Answer: 112 pieces
Step-by-step explanation:
1. Rewrite as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:
2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:
3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:
