Answer: 4

Step-by-step explanation:

The length of QR(x) from the given figure is 4 units.

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

From the given figure, QR=x, RS=2√3 units and ∠STR=60°.

We know that, sinθ= Opposite/Hypotenuse

sin60°=2√3/RT

√3/2=2√3/RT

RT=4 units

As we know, tanθ= Opposite/Adjacent

tan45°= x/4

1= x/4

x=4 units

Therefore, the length of QR(x) from the given figure is 4 units.

Answer:

86°

Step-by-step explanation:

Two sides of the triangle are equal

=> ∠A = ∠C

And since ∠A = 47°

=> ∠C = 47° & ∠B = x°

Now, according to Angle sum property of a triangle

=> ∠A + ∠B + ∠C = 180°

=> 47° + x + 47° = 180°

=> 94° + x = 180°

=> x = 180 - 94 = 86°

Therefore x = 86°

Complete the square:

[tex]\begin{aligned}\implies 4k^2-4k+4 & =4(k^2-k+1)\\ & = 4\left[k^2-k+\left(\dfrac{-1}{2}\right)^2+1-\left(\dfrac{-1}{2}\right)^2\right]\\ & = 4\left[\left(k-\dfrac12\right)^2+\dfrac34\right]\\ & = 4\left(k-\dfrac12\right)^2+3\end{aligned}[/tex]

Answer:

The origin is at (0,0) its where the x and y coordinate intersect.

Step-by-step explanation:

what was the question here?

Step-by-step explanation:

since it is the midsegment, all involved and related line segments follow the 1/2 factor.

so, the length of the midsegment is precisely in the middle between the lengths of the top and bottom lines.

in the first drawing

22 = x + (x - 10)

22 = x + x - 10

32 = x + x = 2x

x = 16

in the second drawing

x = 15 + (15 - 8) = 15 + 7 = 22

For the mean serum cholesterol level for U.S. adults was 198, with a standard deviation of 39,  the probability   is mathematically given as

x=0.1379

Generally, the equation for the probability  is mathematically given as

P(\=x>210)

Therefore

P=(z>\frac{204-198}{39/\sqrt{106}})

P=(z>1.583)

In conclusion, from cumulative table

x=1-p(z>1.583)

x=1-0.8621

x=0.1379

Probability helps us to know the chances of an event occurring. The probability of a family owning a cat or a dog is 0.22.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

As it is given that the probability of a family owning a cat is 0.10, the probability of owning a dog is 0.20, and the probability of owning a cat and a dog is 0.08. Therefore, the probability of a family owning a cat or a dog can be written as,

Probability (family owning a cat or a dog)

= Probability (Cat) + Probability (Dog) - Probability (Cat And Dog)

[tex]\text{Probability (family owning a cat or a dog)} = 0.10+0.20-0.08 = 0.22[/tex]

Hence, the probability of a family owning a cat or a dog is 0.22.

Step-by-step explanation:

Answer:

1. x=4

2. x=14

3. x=3

Step-by-step explanation:

x is just a symbol they use as a temporary symbol to tell the person reading the problem that there is number that you do not know yet. if the x in the problem is next to a number then it needs to be multiplied with the number it's next to. in this case we know that 4 times 3=12 and if you take two away from 12 you get 10 so because 3 works in the equation it's the answer for 4x-2=10. this applies to every problem like this another way to solve it is if you add 2 to the left side it cancels out but you need to add 2 to the other side which would look like 4x=10+2 which equals 4x=12 and 4 times three equals 12. it doesn't matter how the equation changes as long as you find out whatx equals then that is the answer.

Answer:

1. x = 2

2. x = 14

3. x = 3

Step-by-step explanation:

1. 12 + 2x = 16

First, I did 16 - 12 which is 4. I did this because you want to know how much 2x is supposed to be fully, and you always want to do the opposite. like in this case it was addition so the opposite is subtracting. Next, the 2x is supposed to equal 4, and when you see 2x that means you have to multiply. So, 2 x 2 = 4. You can also do 4 divided by 2 equal 4. Finally, the answer for x is 2.

________________________________________________________

2. 12 + x = 26

So, you have to do 26 - 12 which is 14. I turned the addition problem to a subtraction problem because you always want to do the opposite. and you should already know that x will equal 14. you can double check if you want and change it back to addition which will be 12 + 14 = what ? 26 . so 14 is the answer for x !

________________________________________________________

3. 4x - 2 = 10

First, you want to do 10 + 2 which is 12. You should know by now if you read above for the other equations that you have to do the opposite. Next, 4x is going to have to be equal to 12. So, 4 x 3 = 12 or you can do 12 divided by 4 which will still equal 3. Finally the answer for x is 3.

Since F is apparently a vector field, I assume you mean

[tex]\vec F = \nabla(x^3+y^3+z^3+3xyz)[/tex]

with ∇ = gradient, whereas ∆ is often used to denote the Laplacian, ∆ = ∂²/∂x² + ∂²/∂y² + ∂²/∂z².

Let [tex]f(x,y,z)=x^3+y^3+z^3+3xyz[/tex]. Compute the gradient of f :

[tex]\vec F = \nabla f(x,y,z) = \dfrac{\partial f}{\partial x} \, \vec\imath + \dfrac{\partial f}{\partial y} \, \vec\jmath + \dfrac{\partial f}{\partial z} \, \vec k[/tex]

[tex]\vec F = (3x^2+3yz) \,\vec\imath + (3y^2 + 3xz) \,\vec\jmath + (3z^2+3xy) \,\vec k[/tex]

Now compute the divergence of F (incidentally, divergence of a gradient field is the Laplacian of the f):

[tex]\mathrm{div} \, \vec F = \dfrac{\partial(3x^2+3yz)}{\partial x} + \dfrac{\partial(3y^2+3xz)}{\partial y} + \dfrac{\partial(3z^2+3xy)}{\partial z}[/tex]

[tex]\boxed{\mathrm{div} \, \vec F = 6x + 6y + 6z}[/tex]

and the curl: (the following is overkill, since any gradient field has curl zero, but it doesn't hurt to verify that)

[tex]\mathrm{curl}\, \vec F = \left(\dfrac{\partial(3z^2+3xy)}{\partial y} - \dfrac{\partial(3y^2+3xz)}{\partial z}\right) \,\vec\imath - \left(\dfrac{\partial(3z^2+3xy)}{\partial x} - \dfrac{\partial(3x^2+3yz)}{\partial z}\right) \, \vec\jmath \\ ~~~~~~~~~~~~ + \left(\dfrac{\partial(3y^2+3xz)}{\partial x} - \dfrac{\partial(3x^2+3yz)}{\partial y}\right) \,\vec k[/tex]

[tex]\boxed{\mathrm{curl} \,\vec F = \vec 0}[/tex]
