Is (x+1) a factor of the function f(x) = 7x^4 – 5x^3 – 10x² + 2x, and why?

Mathematics
1 answer:
Schach [20]2 years ago
7 0

Answer:

first option

Step-by-step explanation:

If ( x + h) is a factor of f(x) then f(- h) = 0 , then

If (x + 1) is a factor of f(x) then f(- 1) = 0

f(- 1) = 7(-1)^{4} - 5(- 1)³ - 10(- 1)² + 2(- 1)

      = 7(1) - 5(- 1) - 10(1) - 2

     = 7 + 5 - 10 - 2

     = 12 - 12

     = 0

Since f(- 1) = 0 then (x + 1) is a factor of f(x)

On a 20 sided dice what is the probability that a 11 was rolled?
Sedbober [7]

Given:

A 20 sided dice is rolled.

To find:

The probability of getting 11.

Solution:

A 20 sided dice is rolled.

On a 20 sided dice, the possible outputs are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.

Total number of outcomes = 20

Favorable outcomes or number of 11 = 1

Now,

\text{Probability of getting 11}=\dfrac{\text{Favorable outcomes}}{\text{Total number of outcomes}}

\text{Probability of getting 11}=\dfrac{1}{20}

\text{Probability of getting 11}=0.05

Therefore, the probability of getting 11 is 0.05.

A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table:
Ugo [173]

Answer:Is an estimate of the average grams of salt used in 2012

Step-by-step explanation: Let

x ---> the number of years since 2012

f(x) ---> is the total amount of salt ingested in grams

we have

This is a linear equation in slope intercept form

where

The slope is equal to

The y-intercept or initial value is equal to

The y-intercept is the value of the function f(x) when the value of x is equal to zero

In this context, the y-intercept is the average amount of grams of salt ingested  in the year 2012

The exact value of the average amount of grams of salt ingested  in the year 2012 is 3,554 grams (see the data in the table)

Compare the exact value with the y-intercept

therefore

3,548 grams Is an estimate of the average grams of salt used in 2012

-<br> Use the order of operations to simplify 4(3.5 - 1.5) -
irinina [24]

Answer:

When simplified this equation equals 8.

Let me show you my work.  

4 ( 3.5 - 1.5 ) = 4 ( 2 )

4 ( 2 ) = 8 because 4 times 2 = 8

Hope this helps. . .
