Answer: 1/100 or 0.01

In the given figure find out the value of x and y ?​

Answers

Given info:

all sides are equal in the given triangle

It is an equilateral triangle all angles are equal and each angle is equal to 60°

Given angles are 3y° and 2x°

→ 3y° = 2x° = 60°

→ 3y° = 60° and 2x° = 60°

→ y° = 60°/3 and x° = 60°/2

→ y° = 20° and x° = 30°

Therefore, x° = 30° and y° = 20°

Answer:-

The values of x = 30° and y = 20°

Key Knowledge:-

→ If all sides are equal in a triangle then it is an equilateral triangle

In an equilateral triangle,

→ all sides are equal.

→ all angles are equal.

→ all angles are equal to 60°

Pls someone help me with this question

Answers

Step-by-step explanation:

remember, i = sqrt(-1)

you know what an exponent means, right ?

it means you multiply the enclosed term that many times with itself.

when you envision this as a long chain of (1+i)/(1-i) multiplications, you can see you can group them into pairs, and then multiply these pairs - just half the times than for the single terms.

so,

((1+i)/(1-i))²⁰²⁰ = ((1+i)/(1-i))² ^ 1010

to get an idea what the result of the long chain of multiplications might be, let's start with the square and see, if we can find a pattern, that we then can use to come to a conclusion about the total result.

((1+i)/(1-i))² = (1+i)²/(1-i)²

(1+i)² = 1×1 + 1×i + 1×i + i² = 1 + 2i - 1 = 2i

(1-i)² = 1×1 - 1×i - 1×i + i² = 1 - 2i - 1 = -2i

so,

((1+i)/(1-i))² = 2i/-2i = -1

aha !

so,

((1+i)/(1-i))² ^ 1010 = (-1)¹⁰¹⁰

just to be sure you understand, we use the same trick again

(-1)¹⁰¹⁰ = (-1)² ^ 505 = 1⁵⁰⁵ = 1

as 1 to any power is always 1.

so, the right answer is A.

remember, a negative number to an even power results always in a positive number. and to an uneven/odd power in a negative number.

again, because such an exponent is only the summary of many multiplications.

Plug the value of x and y :

When negative integer is multiplied by negative integers , we get positive integer & when positive integer is multiplied by negative integer , we get negative integer.

Step-by-step explanation:

y + 4 ≤ |x-2|

please explain how to solve and graph it. Also please show a graph.
| = an absolute value bar, it kinda looks like 1

Answers

Answer:

y ≤ |x - 2| + 4

Step-by-step explanation:

step (1)

move the 4 to the other side, so it would look like:

y≤ |x-2| + 4

step (2)

now we can start graphing it, you would first start on the x axis moving it to the right. so your point on the graph should be (2,0) {don't graph a point there though}

the reason we do this is because the absolute value means the opposite so everytime there is a number in the absolute value being added or subtracted by just x then we move it the opposite side.

then from that (2,0) we go up four which would now make it (2,4). that is our first point and vertex so graph that.

now in y≤ |x-2| +4 you have to note that if there is nothing next to the equality and the absolute value, then it will become a 1. so our equation will now look like y ≤ 1 |x-2| + 4. so with that from our (2,4) point, we go up one and to the right one and to the left one. So there should be two more points at (3, 5) and (1, 5).

we then keep following the pattern of going up one and the right one and to the left one. the graph line should be in a V shape.

step (3)

now there is one last thing you need to do which is shading. what you're going to do first is check the inequality sign. if the inequality sign has a line under it (meaning equal to) then the line will be a solid line. if it doesn't then there should be a dashed line. our inequality sign has a line under it so it is a solid line.

then we need to figure out where to shade, above or below. if the y is greater than the rest of the equation then that means you need to shade above the V shape. however, if it were to be less than the rest of the equation you would shade below the V shape.

in this problem since the y is less than the rest of the equation, shade downwards.

i hope this answered your question and sorry if my explanation was hard to understand, its a pretty lengthy and confusing but it was the only way i knew of how to explain :))

What is the value of (f. f)(6)?
1) 1 2) 2 3) (4) -2

Answers

A composite function combines two or more functions to generate a new function.

The value of [tex]\mathbf{f(f(6))}[/tex] is -2

The require parameter is:

[tex]\mathbf{f(f(6))}[/tex]

First, we calculate f(6)

From the graph (see attachment)

[tex]\mathbf{f(6) = 2}[/tex]

So, the function [tex]\mathbf{f(f(6))}[/tex] becomes:

[tex]\mathbf{f(2)}[/tex]

In other words,

[tex]\mathbf{f(f(6)) = f(2)}[/tex]

Next, we calculate f(2)

From the graph

[tex]\mathbf{f(2) = -2}[/tex]

So:

[tex]\mathbf{f(f(6)) = -2}[/tex]

Hence, the value of [tex]\mathbf{f(f(6))}[/tex] is -2

Answer:

Step-by-step explanation:

2x + 4x + 180

We have to do combine like terms.

2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.

All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.

The equation of the line in point slope form is:

Answers

Answer:  (y-9) = -4(x-1)

Step-by-step explanation: The format of a point-slope line is y − y1 = m(x − x1), where x1 and y1 are a known point on a line with slope m.  Given slope of -4 and a point of (1,9):

(y − y1) = m(x − x1)

(y − 9) = -4(x − 1)

This can be rearranged to the standard form:  y = -4x+13
