What are the next three numbers in this pattern? 11, 22, 12, 23, . . .

Answers

Answer 1

Answer:

Answer:

13 , 24 , 14

Step-by-step explanation:

Note that technically there are two patterns. Each one adds 1.

The first pattern starts with 11. The third number is 12, which means that the fifth number will be 13, and the 7th number will be 14.

The second pattern starts with 22. The 4th number is 23, which means the sixth number will be 24.

Answer 2

Answer:

Easy, it's going by adding 11's 11+11=22 than it subtracts by 10=12 and it keeps repeating until it's done.

If 3x^2-2x+7=0,then (x-1/3)^2= please help with detailed steps because i dont really understand it. I know the answer is -20/9 but please explain

Answers

Answer:

$-(20)/(9)$

Explanation:

A quadratic function is a kind of function with highest degree 2 . Standard form of the quadratic equation : tex]ax^2+bx+c=0[/tex]

Further explanation:

Consider the given quadratic equation : $3x^2-2x+7=0$

First we divide both sides by 3 , we get

$x^2-(2)/(3)x+(7)/(3)=0$ --------(1)

Compare this equation to $x^2+2ax+a^2$ , we have

$2a=(-2)/(3)$

$\Rightarrow\ a=(-1)/(3)$ [divide both sides by 2]

Now using the completing the squares method , Add and subtract $((-1)/(3))^2$ to the left side in (1), we get

$x^2-(2)/(3)x+((-1)/(3))^2-((-1)/(3))^2+(7)/(3)=0$

It can be written as

$(x^2-2((1)/(3))x+(1)/(3))^2)-(1)/(9)+(7)/(3)=0$

Use identity $x^2-2ax+a^2=(x-a)^2$ , we have

$(x-(1)/(3))^2)+(7(3)-1)/(9)=0$

$(x-(1)/(3))^2)+(20)/(9)=0$

Subtract $(20)/(9)$ from both the sides , we get

$(x-(1)/(3))^2)=-(20)/(9)$

Therefore, the value of $(x-(1)/(3))^2)=-(20)/(9)$

For this case we have the following polynomial:

$3x^2-2x+7=0$

To solve the problem, we must complete squares.

The first step is to divide the entire expression by 3.

We have then:

$(3)/(3)x^2-(2)/(3)x+(7)/(3)=0$

The second step is to place the constant term on the right side of the equation:

$(3)/(3)x^2-(2)/(3)x=-(7)/(3)$

The third step is to complete the square:

$(3)/(3)x^2-(2)/(3)x + (-(1)/(3))^2=-(7)/(3)+ (-(1)/(3))^2$

Rewriting we have:

$x^2-(2)/(3)x + (1)/(9)=-(7)/(3)+ (1)/(9)$

$(x-(1)/(3))^2 = -(20)/(3)$

Answer:

By completing squares we have:

$(x-(1)/(3))^2 = -(20)/(3)$

Every week Perry gets paid $150 plus 12% of his total sales amount. Solve the equation 840=150+0.12(a−1,250) for a to find the total amount Perry must sell in order to be paid $840 in one week.

Answers

The total amount Perry must sell in order to be paid $840 in one week will be $7,000.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Every week Perry gets paid $150 plus 12% of the number of his total sales. The total amount Perry must sell in order to be paid $840 in one week is given as,

840 = 150 + 0.12(a − 1,250)

Simplify the equation, then we have

840 = 150 + 0.12(a − 1,250)

690 = 0.12 × (a − 1,250)

(a − 1,250) = 5,750

a = $7,000

The total amount Perry must sell in order to be paid $840 in one week will be $7,000.
