Answer:

sin (2A+2B) = 0

Step-by-step explanation:

Given that,

cosec A= -2 and sec B= -2, A and B lie in the same quadrant.

We need to find the value of sin (2A+2B).

[tex]A=cosec^{-1}(-2)\\\\=-30[/tex]

And

[tex]B=\sec^{-1}(-2)\\\\=120^{\circ}[/tex]

To find the value of sin (2A+2B) as follows :

sin [2(-30)+2(120)] = sin (-60+240)

=sin (180)

= 0

So, the value of sin (2A+2B) is qual to 0.

Answer:

x = 3, the error is that the -2x should be added.

Step-by-step explanation:

The -2x should be added to the left side.

3x - 7 = -2x + 8

3x + 2x = 8 + 7

5x = 15

x =3

Answer:

x=5

Step-by-step explanation:

Correct way:

Add 2x to 3x ( 5x )

3x-7=8

Add 7 to 8 ( 15 )

3x=15

Divide 15/3

x= 5

What was wrong:

You need to combine like terms and put the variable on the left side of the equation and then follow the steps above. You also forgot to divide.

Answer:36%

Step-by-step  have 12+18+20 which equals 50 and 18 out of 50 is 36%

The percentage of the students who chose chocolate as their favorite ice cream flavor will be 36%

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.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

It is given that, there are  18 students voted for chocolate,12 students voted for strawberry and 20 students voted for vanilla.

The total number of students = 18+12+20 = 50

A percentage of the students chose chocolate as their favorite ice cream flavor is,

%choclate = (Number of students voted for chocolate / Total student)×100

%choclate =(18/50)×100

%choclate =36%

Answer:

x=11, y=1 or (11, 1)

Step-by-step explanation:

I used substitution to solve this. Basically wherever there's an x, I would fill it in as 12-y.

2(12-y)+3y=29

24+2y+3y=29

24+5y=29

subtract 24 from both sides

5y=5

divide by 5

y=1

Now substitute y back in to get x.

x=12-1

x=11

You can also graph this into desmos, and wherever they intercept, that's your answer.  I hope this helps!

Since S is closed, you can use the divergence theorem, which says

[tex]\displaystyle\iint_S \vec F(x,y,z) \cdot \mathrm d\vec S=\iiint_R \mathrm{div}\vec F(x,y,z)\,\mathrm dV[/tex]

where R is the interior of the surface S.

We have

div F (x, y, z) = ∂/∂x (0) + ∂/∂y (y) + ∂/∂z (-z) = 1 - 1 = 0

so the flux would be 0.

In this exercise we have to calculate the flux by the divergent theorem:

The flux would be ZERO

Since S is closed, you can use the divergence theorem, which says:

[tex]\int\limits\int\limits_s {F(x,y,z} \, ds= \int\limits \int\limits\int\limits_R {divF(x, y, z)} \, dv[/tex]

where R is the interior of the surface S. We have:

[tex]\nabla F (x, y, z) = 1-1= 0[/tex]

so the flux would be ZERO.

Answer:

A 3 1/2

Step-by-step explanation:

There are a number of ways that you can solve this

Method 1)

Since these proportions are set equal to each other, we know that x is also equivalent to 1/2. So, we need to find the whole-number that was multiplied by the first fraction (1/2/4) that gave us the second fraction (x/28).

So we need to divide the denominators

28/4 = 7

Now that we have that number, we will mutiply 1/2 by it because we know that whatever x is the 1/2 times 7 since 28 is 4*7:

1/2 * 7 = 3.5 or 3 1/2, so 3 1/2 is our answer...

Another way that we can solve this is by using the cross product (butterfly method)

Method 2)

Multiply 28 by 1/2 = 14.

Now we will divide 14 by 4. 14/4 = 3.5

3.5 = 3 1/2, so that is our answer.

Step-by-step explanation:

Answer: x=60

Step-by-step explanation:

x+22+x+6+x−28=180

Step 1: Simplify both sides of the equation.

x+22+x+6+x−28=180

x+22+x+6+x+−28=180

(x+x+x)+(22+6+−28)=180(Combine Like Terms)  22+6=28 and then 28-28=0

3x=180  

3x=180

Step 2: Divide both sides by 3.

3x/3 = 180/3

x=60

hope this was helpful.

Answer:

3x = 0

Step-by-step explanation:

Given,

y = 10

now,

5x+2y = 20

or, 5x+2×10=20

or, 5x = 20-20

or, 5x = 0

or, x = 0/5

or, x = 0

Again,

3x = 3×0 =0

Answer:

(x, y) Right-arrow (x – 3, y + 4)

(the top one)

applying the appropriate transactional rule When the coordinates are added to or subtracted from, the values of x and y change.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given four transformations of coordinates (x, y)

Mathematical transformations describe how 2D figures move around a plane or coordinate system.

thus for (x, y ) => (x - 3), (y + 4)

From the given rule:

x is decreased by 3 and y is increased by 4 or in other words, we can say the graph moves downward by 3 units and to the right by 4 unit

for (x, y ) => (x + 3), (y - 4)

From the given rule:

x is increased by 3 and y is decreased by 4 or in other words, we can say the graph moves upward by 3 units and to the left by 4 units.

for (x, y ) => (x + 4), (y - 3)

From the given rule:

x is increased by 4 and y is decreased by 3 or in other words, we can say the graph moves upward by 4 units and to the left by 3 units.

Therefore, using the correct rule of the transaction The value of x and y will increase or decrease by adding or subtracting from the coordinates.
