Answer:

It would be 9+2n.

Step-by-step explanation:

Sinve you have not given us an equation, twice a number can also be reresented as 2n. Since 9 is the constant, you can say 9+2n.

Is x-8 a factor of p(x)= x3-9x2+12x-17
BartSMP [9]

x-8 is not a factor of p(x) = x^3-9x^2+12x-17

Step-by-step explanation:

In order to check whether a term is factor of given expression or not we put the value in the expression. If the expression is zero, then the value is a factor otherwise not.

Given polynomial is:

p(x) = x^3-9x^2+12x-17

We have to check if x-8 is factor of given polynomial or not. for that purpose we have to put

x-8 = 0\\x = 8

Putting in the polynomial

p(x) = (8)^3 - 9(8)^2+12(8)-17\\= 512 - 8(64) + 96 - 17\\= 512-512+96-17\\=79

Hence,

x-8 is not a factor of p(x) = x^3-9x^2+12x-17

The nth term of this sequence is ansquared+by+c<br> 1,11,27,49 <br> Find the values of a b and c
stiv31 [10]

Answer:

The values of a, b and c are:

  • a = 3
  • b = 1
  • c = -3

Step-by-step explanation:

Step 1:

First Confirm the sequence is quadratic by finding the second difference.

Sequence = 1,11,27,49

1st difference:

  • 11-1=10
  • 27-11=16
  • 49-27=22

2nd difference:

  • 16-10=6
  • 22-16=6

Step 2:

Just divide the second difference by 2, you will get the value of a.

6 ÷ 2 = 3

So the first term of the nth term is 3n^{2}

Step 3: Next, substitute the number 1 to 5 into  3n^{2}

n = 1,2,3,4,5

3n² = 3,12,27,48,75

Step 4:

Now, take these values (3n²) from the numbers in the original number sequence and work out the nth term of these numbers that form a linear sequence.

n = 1,2,3,4,5

3n² = 3,12,27,48,75

Differences:

1 - 3 = -2

11 - 12 = -1

27 - 27 = 0

49 - 48 = 1

Now the nth term of these differences (-2,-1,0,1) is (n - 1) - 2.

so b = 1, and c = -3

Step 5: Write down your final answer in the form an² + bn + c.

3n² + (n - 1) -2

= 3n² + n - 1 - 2

= 3n² + n - 3

Therefore, the values of a, b and c are:

  • a = 3
  • b = 1
  • c = -3

Answer: 80 Fluid Oz

Step-by-step explanation:

I first have to find out how many fluid Oz there are in one bottle. If there are 16 Oz in 2 bottles, I have to divide 16/2=8. Now I know there are 8 Oz in each bottle. Now I have to multiply 8 by 10. 10*8=80. There is 80 Oz all together.

Hope this helps! :)

Which situation best shows causation?
dangina [55]

A cause and effect relationship exist between two variables, when one

variable event is made to happen by the other variable.

The situation which best shows causation is option <u>B) The amount of time a </u>

<u>cell phone is used affects the charge of the battery</u>.

Reasons:

Causation is the condition in which the occurrence of an event is caused by

or contributed to by another event. Such that the incident or observation

identified as the cause is responsible for the event, while the the

occurrence of the event depends on the cause being put in place.

  • Option A) A rectangle of a given width can have different dimensions of length

  • Option C) Milkshakes and ice cream bars can have different customer base, such that the number of milkshake and ice cream bars sold can be equal

  • Option D) The balls used in a soccer match are provided by the officials of the game

Therefore;

  • The situation which shows causation is B) <u>The amount of time a cell phone is used affects the charge of the battery</u>.

The option is correct because, a cell phone is powered by battery, and

therefore, the more the cell phone is used, the battery power is used up

and therefore, the charge on the battery is reduced.
