Question:

Given a polynomial f(x), if (x − 4) is a factor, what else must be true?

f(0) = 4
f(0) = −4
f(4) = 0
f(−4) = 0

_______________________________________

Solution:

f(x) is a polynomial.

(x - 4) is a polynomial of f(x).

By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.

On comparing (x - 4) with (x - a), we get,

a = 4

So,

f(a) = 0

=> f(4) = 0

umka21 [38]

Answer:

Option A 0.312 is right

Step-by-step explanation:

Given that iN Maplewood a certain type of DVD player is sold at just two stores, 43% of the sales 13) are from store A and 57% of the sales are from store B. 2.4% of the DVD players sold at store A are defective while 4.0% of the DVD players sold at store B are defective.

Prob for any random item form store to be defective = Prob from A and defective +Prob from B and defective

= $0.43(0.024)+0.57(0.04)\\=0.03312$

Prob it came from A and defective = 0. $0.43(0.024)=0.01032$

If Kate receives one of these DVD players as a gift and finds that it is defective, what is the probability that it came from store A

= $\frac{0.01032}{0.03312} \\=0.312$

Sokhem is Chanda's older brother.In six more years Sockem will be twice chendas age now.In six more years the sum of their ages

const2013 [10]

Answer:

Sokhem: 30
Chanda: 18

Step-by-step explanation:

Let c represent Chanda's age now. In six years, the Sokhem's age will be 2c. At that time, the sum of their ages is ...

(c+6) +2c = 60

3c = 54 . . . . . . . . subtract 6, collect terms

c = 18 . . . . . . . . . . divide by 3

Chanda is 18, Sokhem is 30.

_____

Check

In 6 years Chanda will be 24, Sokhem will be 36. The sum of their ages then will be 24+36 = 60. Since Chanda is 18 now, Sokhem's age then will be 2 times Chanda's age now.
