Answer:the binomial that is not a factor is x - 4

Step-by-step explanation:

The given polynomial is expressed as

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

The first step is to equate the polynomial to zero. It becomes

P(x) = 3x^3 + 5x^2 - 4x - 4 = 0

We would substitute each value of x into the polynomial. If the result is zero, then it is a factor.

1) x - 4 = 0, x = 4

Therefore,

3×4^3 + 5 × 4^2 - 4 × 4 - 4 = 0

384 + 80 - 16 - 4 = 444

2) x + 2 = 0, x = - 2

Therefore,

3 × -2^3 + 5 × -2^2 - 4 × -2 - 4 = 0

- 24 + 20 + 8 - 4 = 0

3) x = 1

Therefore,

3 × 1^3 + 5 × 1^2 - 4 × 1 - 4 = 0

4) 3x + 2 = 0

3x = - 2

x = - 2/3

Therefore

3 × (-2/3)^3 + 5 × (-2/3)^2 - 4 × (-2/3) - 4 = 0

What two whole numbers is 29−−√ between?: 3 and 4 4 and 5 5 and 6 6 and 7

jolli1 [7]

The two whole numbers are 5 and 6 ⇒ 3rd answer

Step-by-step explanation:

To prove that a square root number lies between which two consecutive integers do that

Find a square number less than the number under the root
Find a square number greater than the number under the root
Find the square root of the square numbers, they will be the two integers that the root lies between them

∵ The number is $\sqrt{29}$

- Find a square number less than 29

∵ 25 is a square number

∵ 25 is less than 29

- Find a square number greater than 29

∵ 36 is a square number

∵ 36 is greater than 29

∴ 25 < 29 < 36

- Take √ for each number

∴ $\sqrt{25}$ < $\sqrt{29}$ < $\sqrt{36}$

∵ $\sqrt{25}$ = 5

∵ $\sqrt{36}$ = 6

∴ 5 < $\sqrt{29}$ < 6

The two whole numbers are 5 and 6

A used car was purchased in July 1999 for $11,900. If the car depreciates 13% of it's value each year, what is the value of the

trapecia [35]

1999 price = 11900
it depreciates 13%
$\frac{13}{100} \times 11900 = 1547$
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
$\frac{13}{100} \times 10353 = 1345.89$
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
$\frac{13}{100} \times 9007.11 = 1170.92$
year 2002 cost = 9007.11 - 1170.92 = 7836.19

The population of kansas city, missouri was 435,000 in 1990 and 482,300 in 2005. if the population is changing linearly, write a

Jlenok [28]

Find the slope of the line connecting (1990,435000) and (2005,482300):

482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr

Use the point-slope formula to find the equation of this str. line:

y-435000 = (3153/yr)(x-1990)

The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is

given by y-435000 = 3153(30) = 94590, so that y = 529590.
