f(2)=3x^2-6x+2
I need help!!!

Answer:

Step-by-step explanation:

you can start by factoring x

x(2x³-x²-18x+9)

you can group terms in parentheses strategicly

x(2x³-18x-x²+9)=x[2x(x²-9)-(x²-9)]

now we can factor x²-9

x(x²-9)(2x-1)

factor the diference of two squares x²-9=x²-3²

x(x-3)(x+3)(2x-1)

so the roots are found by using the zero product rule

x(x-3)(x+3)(2x-1)=0 will give

x=0, x-3=0 so x=3, x+3=0 so x=-3, 2x-1=0 so x=1/2

from left to right

-3, 0, 1/2, 3

Answer:

1. -3

2. 0

3. 1/2

4. 3

Answer:

15

Step-by-step explanation:

Given that:

Three six-sided dices are to be rolled.

The number of ways to have the same value on the two dices is:

{(1,1) ,(2,2) ,(3,3) ,(4,4) , (5, 5 ) ,(6 ,6) }  = 6 ways

Thus; the objective is to determine the number of ways to a get smaller value on the third dice  while the two other dice have the same value.

To get started:

The number of ways for getting a value smaller than 1 = 0

The number of ways for getting a value smaller than 2 = 1

{i.e. (2,2,1)}

The number of ways for getting a value smaller than 3 = 2

{ i.e. (3,3,1) ,(3,3,2) }

The number of ways for getting a value smaller than 4 = 3

{ i.e. (4,4,1) , (4,4,2), (4,4,3)}

The number of ways for getting a value smaller than 5 = 4

{i.e. (5 ,5,1) ,(5,5,2) ,(5,5,3), (5,5,4)}

The number of ways for getting a value smaller than 6  = 5

{i.e. (6,6,1), (6,6,2), (6,6,3), (6,6,4), (6,6,5) }

Thus, the total number of ways = 0 + 1 + 2 + 3 + 4 + 5 = 15

Therefore, the total number of ways getting the value same on two dices and smaller value on the third dice = 15

Answer:

Step-by-step explanation:

5 x ( 9 + 4 ) = ( 5 x __ ) + ( 5 x __ )

using distributive property,

the answer is

( 5 x 9 ) + ( 5 x 4 )

if u want the final answer

it becomes

45 + 20

= 65

Answer:

It does

Step-by-step explanation:

It does have a proportional relationship because if you try to find the relationship between the first two inputs and outputs, you can find that it is 21 (1 to 21, 21 divided by 1 would be 21) then if you use that relationship with the other numbers (times 21) you would get the same answer. For example in the second one, the two numbers are 2 and 42, 2 times 21 would equal 42. The next one would be 3 times 21 to equal 63 and etc.

Step-by-step explanation:

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 1/35 of gas to go 1 mile.

Answer:

182.353745455

Answer:180

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

(3/4)/(9/2)=1/6 tank of gas used every hour.

1/6*12=2 tanks of gas used in 12 hours.

By using the unitary method we will get 2 tanks of gas will anna use after 12 hours.

The unitary method is a method of determining the value of a single unit and based on that value you can find the value for the number of units you need.

Let the volume of the tank of gas  be x units

Volume of the tank of gas  uses for  9/2 hours = 3/4 of total volume

                                                         = 3/4 x

Volume of the tank of gas uses after 1 hour = 3/4 x ÷ 9/2

                                                                         = 3/4 x × 2/9

                                                                          = x/6

Volume of the tank of gas uses after 12 hours =x/6  x× 12 = 2x

Here, 2x  shows that 2 tanks of gas will anna use after 12 hours.

Therefore , 2 tanks of gas will be used by anna.

Answer: (0.1118, 0.3454)

Step-by-step explanation:

Confidence interval for population proportion is given by :-

[tex]\hat{p}\pm z^c\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex] , where [tex]\hat{p}[/tex]= sample proportion , n= sample size, [tex]z^c[/tex] = critical z-value for c confidence level.

Let p = the proportion of all households in Cherry Creek that pretend not to be home on Halloween.

Given : n= 35

[tex]\hat{p}=\dfrac{8}{35}\approx0.2286[/tex]

Critical z-value for 90% confidence level =1.645

A 90% confidence interval for p, the proportion of all households in Cherry Creek that pretend not to be home on Halloween:

[tex]0.2286\pm (1.645)\sqrt{\dfrac{0.2286(1-0.2286)}{35}}\\\\=0.2286\pm 0.1168\\\\=(0.2286-0.1168,\ 0.2286+0.1168)\\\\=(0.1118,\ 0.3454)[/tex]

∴ Required confidence interval : (0.1118, 0.3454)

Step-by-step explanation:

Answer:

when

[tex]x\ge 0[/tex]

then

[tex]x\times \left|x\right|=x^{2}[/tex]

Step-by-step explanation:

As we know that

When x is positive

[tex]\left|x\right|=\:x[/tex]

As from the question,

[tex]x\ge 0[/tex]

so the expression will be:

[tex]x\times \left|x\right|=x\times x=x^2[/tex]      ∵ [tex]x\ge 0[/tex] so [tex]\left|x\right|=\:x[/tex]

Therefore,

[tex]x\times \left|x\right|=x^{2}[/tex]

Answer:

The width of the confidence interval is going to be wider

Step-by-step explanation:

When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;

The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.
