= 4(3x^3 - 15x^2 + x - 5)

 product of first coefficient and -5 is -15  so  one factor could be x +/ 3) or x +/- 5)

using the factor theorem   f(5) =  375 - 375=5-5 = 0  so (x - 5) is a factor:-

so we have  4(x - 5)(3x^2 + 1)   Answer

Quality control finds on average that 0.026% of the items from a certain factory are detective. One month, 4000 items are checke
telo118 [61]

Given that 4000 items are checked in one month, let the number of detective items be represented as y.

Quality control finds on average that 0.026% of the items in the factory are detective. This implies that

\text{Number of }\det ective\text{ items = }\frac{\text{0.026}}{100}\times\text{Total number of items checked}

When 4000 items are checked, we have the number of detective items to be evaluated as

\begin{gathered} \text{Number of }\det ective\text{ items = }\frac{\text{0.026}}{100}\times\text{Total number of items checked} \\ y=\frac{0.026}{100}\times4000 \\ \Rightarrow y=1.04 \end{gathered}

Hence, the number of detective items is 1.04.

The given function models the number of cars that are put through a quality control test each hour at a car production factory.
Annette [7]

hours each day.

Step-by-step explanation:

The given function models the number of cars that are put through a quality control test each hour at a car production factory.

The given function is

We need to find the number of hours does the quality control facility operate each day.

Rewrite the given function it factored form.

Taking out the common factors from each parenthesis.

The factored form of given function is c(t)=-(t-10)(t+2).

Equate the function equal to 0 to find the x-intercept.

Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.

Therefore the quality control facility operates for 10 hours each day.
