Which Is Irrational?

Answers

Answer 1

Answer:

  (b)  √5

Step-by-step explanation:

The square root of an integer is rational if the integer is a perfect square. You probably know the first few perfect square integers are 1, 4, 9, 16, 25, 36, ...

The integer 5 is not on that list, so its square root will be irrational.

  √5 is irrational

now,1x=2y

or, 1(15+y)=2y

or, 15+y=2y

or, 15=2y-y

or, y=15

now,putting the value of y

x=15+y

What is the equation of the line that passes through the points (6,-9 )and (3,-8)

Answers

Answer:

y = (-1/3)x - 7

or

y + 8 = (-1/3)(x - 3)

Step-by-step explanation:

First, find the slope (rise over run):

Δy / Δx = (-8 + 9) / (3 - 6) = 1 / -3 = -1/3

Then use one of the given points to put it into point-slope form:

y + 8 = (-1/3)(x - 3)

or optionally in slope-intercept form:

y = (-1/3)x - 7

The graph of y=tan(x) is vertically stretched by a factor of 7, shifted a distance of 12 units to the left, reflected across the x-axis, and then translated 15 units downward. Write the equation for the curve in its final position.

Answers

Step-by-step explanation:

A transformation(s) of a parent function is

[tex]f(x) = a(bx - c) + d[/tex]

where a is vertical compression/stretched or reflection

B is horinzotnal compression/stretch or reflection

C is horinzontal translation

D is vertical translation.

The parent function is

[tex]y = \tan(x) [/tex]

First, we stretched this by 7

so we have

[tex]y = 7 \tan(x) [/tex]

We need to shift this 12 units to the left so we have

[tex]y = 7 \tan(x + 12) [/tex]

We need to reflect this across x axis so we get

[tex]y = - 7 \tan(x + 12) [/tex]

We need to shift this downwards 15 so we get

[tex]y = - 7 \tan(x + 12) - 15[/tex]

or because tan is a odd function you could say

[tex]7 \tan( - (x + 12) ) - 15[/tex]

[tex]7 \tan( - x - 12) - 15[/tex]

What’s the formula for the statement of retained earnings and can someone please tell me????? I have an accounting test next week and I need helpppp asapppppppp

Answers

Answer:

Current Retained Earnings + Profit/Loss – Dividends = Retained Earnings

Step-by-step explanation:

Let’s say your company went into business on January 3, 2022. Your retained earnings account on January 3, 2022, will read $0 because you have no earnings to retain.

Now let’s say that in January you earn $5,000 in net income (from your income statement) and don’t issue any dividends.

That means that on February 3, your company’s retained earnings will be $5,000:

Current retained earnings + Net income - Dividends = Retained earnings

$0 + $5,000 - $0 = $5,000

This makes sense: you earned $5,000 in profits and retained all of them.

hope it helps you

make me brainliest...... :)

The number is 27.2, and the number 9.411 is 170% of 16 after applying the concept of the percentage.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

170% of 16

Let x be the number:

170 % of 16 = x

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

(170/100)16 = x

1.7(16)  = x

x = 27.2

Thus, the number is 27.2, and the number 9.411 is 170% of 16 after applying the concept of the percentage.

What is the slope and Y intercept of the equation Y=9

Answers

Answer:

y-intercept = 9

slope = 0

Step-by-step explanation:

y = 9 is a horizontal line that passes through the point (0, 9).

The y-intercept is 9.

The slope is 0.

[tex]\huge\fbox{Hi~there!}[/tex]

We are given the equation of the line: [tex]\rm{y=9}[/tex] and asked to determine its slope and y-intercept.

The equation of this line is written in slope-intercept form (y=mx+b)

where b is the y-intercept of the line, and m is the slope.

Now, the big question is:

What is the slope and y-intercept of the line?

We need to take a look at the equation to find out.

As we can see, the slope is 0, and the y-intercept is 9.

I hope you find it helpful.

What type of special triangles are created when an equilateral triangle has a perpendicular bisector applied? *

Answers

Answer:

Two 30°-60°-90° triangles

Explanation:

An equilateral triangle always has three 60° angles. If you were to cut it in half with a perpendicular bisector, two 90° angles would be made with the perpendicular lines, two 30° angles would be made from the corner that the bisector cut in half, and two of the three 60° degree angles would have remained untouched.
