Answers

We can see the sequence A in the picture. Each term is more then the previous term and each term is the previous term multiplied by 2. (Aₙ=n-1 and Bₙ=2ⁿ⁻¹).

Given that,

We can see in the picture.

We have to describe how to create each new word from the prior term in sequence A.

From the 4 option

Option 1 is true because in the picture we can see each term is the previous term multiplied by 2.

Option 4 is true because in the picture we can see that each term is more then the previous term.

From row 1 and row to 2 in the picture we can say that.

We can say Aₙ=n-1 and Bₙ=2ⁿ⁻¹

We can find the slope by using rise/run

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{5-(-2)}{4-4} \\[/tex]

As expected, the slope is indeed undefined. The denominator can't be 0 but this one has denominator that's 0 which is undefined.

Meaning that, when the x-value for both ordered pairs are the same, the slope will be undefined.

For the graph, It should be like this below in the picture.

can someone explain what rise over run means pls

Answers

Step-by-step explanation:

Rise over run is often referred to as the slope of the line or the gradient of the line. It is the measure obtained by dividing the y component of the line with the x component of the line. The rise over run ratio is an important characteristic to define the line, and is required to find the equation of the line.

|2x-4|+6=8​

Answers

Solve for x

|2x -4| + 6 =8

subtract 6 from both sides, then solve

|2x - 4| = 2                                   and                                 |2x -4| = -2

2x - 4 = 2                                                                           2x - 4 = -2

     +4   +4                                                                                +4  +4

2x = 6                                                                                   2x = 2

divide by 2 to isolate the variable

x = 3                                                                                    x = 1

Rational Number is defined as the number which can be written in a ratio of two integers. An irrational number is a number which cannot be expressed in a ratio of two integers. ... Conversely, irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern.

Answers

Answer:

The rational number includes only those decimals, which are finite and repeating.

Step-by-step explanation:

Rational Number is defined as the number which can be written in a ratio of two integers in the form a/b where a,b are integers and b≠ 0, while an irrational number is a number which cannot be expressed in a ratio of two integers (that is it cannot be expressed as fraction in the form a/b).

The rational numbers are numbers whose decimal expansion are finite and repeating, while irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern e.g. π.

For Plato

The profits of Mr. Unlucky's company can be represented by the equation f(x)=−3x^2+18x−4, where y is the amount of profit in hundreds of thousands of dollars and x is the number of years of operation. He realizes his company is on the downturn and wishes to sell before he ends up in debt.What is the maximum profit?

Answers

Answer:

Step-by-step explanation:

maximum years would be where x=-b/2a or -18/-6 or x=3

put that into the equation to get y=-27+54-4=23 hundreds of thousands.

from year 3 on, the profit decreases

the zero point is where y=0 this is -3x^2+18x-4=0

or 3x^2-18x+4=0

quadratic formula

x=(1/6)(18+/-sqrt(324-48)); sqrt 276=16.61

x=(34.61/6)=5.77 years, so 2.77 years of decreasing profits.

y = ± [tex]\sqrt{169}[/tex] = ± 13
