Given info:

all sides are equal in the given triangle

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°

Hope this helps!!

Answer:

He moved 7 hash marks and the product is $1.60

Step-by-step explanation:

It’s says he starts at 0.2 on the number line, so that’s the second hash mark after the 0. If you move to the right on each hash all the way til the 2, you moved 7 times.

The product of 8 x .20 = 1.60

Answer:

336

Step-by-step explanation:

just took the test

The correct answer is 336.

By using the arrangement calculation formula:

⇒ [tex]A^{3}[/tex][tex]^{8}[/tex]  

⇒ 8 × 7 × 6

⇒ 336

The correct answer is 336.

Remember that combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula NCR = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

Answer:

Step-by-step explanation:

Considering the zeros, the graph for the sinusoidal function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The sine function is given by:

[tex]F(x) = A\sin{Bx}[/tex]

In which:

In this problem:

[tex]\frac{2\pi}{B} = 14[/tex]

[tex]B = \frac{2\pi}{14}[/tex]

[tex]B = \frac{\pi}{7}[/tex]

Thus:

[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]

Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

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

Answer:  I believe it is -38

Step-by-step explanation:

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.

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 :))

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.

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
