After answering the presented question, we can conclude that Pythagorean theorem Therefore, the value of x is 15.

The Pythagorean theorem is a fundamental mathematical principle that describes the relationship between the sides of a right triangle. It states that the sum of the squares of the other two sides' lengths equals the square of the hypotenuse's length (the side opposite the right angle). The mathematical theorem is as follows: c2 = a2 + b2 Where "c" denotes the hypotenuse length and "a" and "b" represent the lengths of the other two sides, known as the legs.

Pythagorean theorem

\(x^2 = 12^2 + y^2\\y/x = 3/5\\y = (3/5)x\\x^2 = 12^2 + (3/5)^2 x^2\\(1 - (3/5)^2) x^2 = 12^2\\(1 - 9/25) x^2 = 12^2\\(16/25) x^2 = 12^2\\x^2 = (25/16) * (12^2)\\x = (5/4) * 12 = 15\\\)

Therefore, the value of x is 15.

Point slope form of the equations:

y = -3x + 8

y = 2x - 2

Solution to the system of equations:

(x, y) ==> (2, 4)

Step-by-step explanation:

6x + 2y = 16

2x - y = 2

6x + 2y = 16

2(2x - y = 2)  ==> 4x - 2y = 4

6x + 2y = 16

4x - 2y = 4

10x = 20

/10     /10

x = 2

Now, we solve for y:

6x + 2y = 16

6(2) + 2y = 16

12 + 2y = 16

-12         -12

2y = 4

/2   /2

y = 2

If you wanted to save $30,000 you need to work 30 times .

Given:

if you wanted to save $30,000 to buy a new car. instead of focusing on saving the whole amount, you work to earn $1,000 at a time. this makes the process seem more manageable to you because you are using the heuristic.

Number of times to work = money to save / at a time money.

When the volume of this sphere is \($\frac{K \sqrt{6}}{\sqrt{\pi}}$\), then the value of K is 8

As per the data given:

The length of the cube is 2 units.

First, we have to determine the surface area of the cube.

The formula for the surface area of the cube:

A = 6 (side × side)

A = 6 (2 × 2)

A = 6 (4)

A = 24 square units

The surface area of a cube is 24 square units.

Also given that the surface area of a cube and the surface area of a sphere is equal.

The formula for the surface area of the sphere.

A = 4π \(r^{2}\)

Where r is the radius of the sphere.

4π \(r^{2}\) = 24

π \(r^{2}\) = 6

\(r^{2}\) = \(\frac{6}{\pi }\)

r = \(\sqrt{\frac{6}{\pi } }\)

The radius of the sphere is \(\sqrt{\frac{6}{\pi } }\)

Also given the volume of the sphere as \($\frac{K \sqrt{6}}{\sqrt{\pi}}$\)

Here we have to determine the value of K.

The volume of sphere = \(\frac{4}{3} \pi r^{3}\)

Where r is the radius of the sphere.

\(\frac{4}{3} \pi r^{3}\) =    \($\frac{K \sqrt{6}}{\sqrt{\pi}}$\)

\(\frac{4}{3} \pi (\sqrt{\frac{6}{\pi } }) ^{3} = \frac{K \sqrt{6} }{\sqrt{\pi } }\)

\(\frac{4}{3} \pi {\frac{6}{\pi } }= K\)

K = 4 × 2

K = 8.

Therefore the value of K = 8.

The volume of water in the cone-shaped paper cup is 25.12 cubic centimeters.

To calculate the volume of water in the cone-shaped paper cup, we can use the formula for the volume of a cone:

V = (1/3) * π * r^2 * h

Given:

Height of water (h) = 6 cm

Diameter of the top surface of water (2r) = 4 cm

First, we need to find the radius (r) of the top surface of the water. Since the diameter is given as 4 cm, the radius is half of that:

r = 4 cm / 2 = 2 cm

Now we can substitute the values into the volume formula and calculate the volume of water:

V = (1/3) * 3.14 * (2 cm)^2 * 6 cm

V = (1/3) * 3.14 * 4 cm^2 * 6 cm

V = (1/3) * 3.14 * 24 cm^3

V = 25.12 cm^3.

The change in profit (ΔP) when the number of units (Δx) increases by 5, based on the given marginal profit function, is -18331.50

To find the change in profit (ΔP) when the number of units (Δx) increases by 5.

we need to evaluate the marginal profit function and multiply it by Δx.

The marginal profit function is given by dP/dx = 12.1(60 - 3x).

We are given the value of x as 121, so we can substitute it into the marginal profit function to find the marginal profit at that point.

dP/dx = 12.1(60 - 3(121))

= 12.1(60 - 363)

= 12.1(-303)

= -3666.3

Now, we can calculate the change in profit (ΔP) by multiplying the marginal profit by Δx, which is 5 in this case.

ΔP = dP/dx×Δx

= -3666.3 × 5

= -18331.5

The possible values of angle ∠G are 58.5° or 121.5°.

As per data,

In ΔEFG, g = 6.1 cm, f = 7.3 cm and ∠F = 69°.

We have to find all possible values of ∠G, to the nearest 10th of a degree.

To find ∠G, we have to use the sine law.

Sine Law states that

a/sinA = b/sinB = c/sinC

Where a, b, and c are the lengths of the sides opposite to the angles A, B, and C respectively.

Now, as per the sine law, we have

a/sinA = b/sinB = c/sinC

f/sinF = g/sinG

We are given, f = 7.3 cm, sinF = sin 69°, and g = 6.1 cm.

Substituting the given values in the above equation, we have

7.3/sin69° = 6.1/sin G

Simplify values,

sin G = (6.1 × sin69°) / 7.3

We know, 0 < G < 180°        

∴ the possible values of

∠G = sin⁻¹ ((6.1 × sin69°) / 7.3)

Thus, we get the possible values of ∠G to the nearest 10th of a degree as follows:

∠G ≈ 58.5° or 121.5°

Hence, the possible values of ∠G are 58.5° or 121.5°.

No, the statement the surface area of Cube B is also twice that of Cube A, is False.

Cube A is of 2 by 2 by 2

So the length of each side of Cube A is 2 units

So the surface area of Cube A = 6*2*2 = 24 square units

Cube B is of 4 by 4 by 4

So each side length of Cube B is 4 units

So the surface area of Cube B = 6*4*4 = 96 square units

So Surface area of Cube B is = 96/24 = 4 times of surface area of Cube A.

The Cartesian equation for the curve r = 4csc(θ) is (x^2 + y^2) * y = 4, and it represents a semi-cubical parabola.

To find a Cartesian equation for the curve r = 4csc(θ) and identify it, we can follow these steps:

Step 1: Rewrite the equation using the definition of cosecant
Cosecant (csc) is the reciprocal of sine, so we can rewrite the equation as:
r = 4/sin(θ)

Step 2: Express r and θ in Cartesian coordinates
We know that r^2 = x^2 + y^2 and y = r * sin(θ). We can use these relationships to replace r and θ with x and y in our equation. First, we solve for sin(θ):
sin(θ) = y / r

Step 3: Substitute sin(θ) and r in the equation
Now, replace sin(θ) and r in the original equation:
r = 4/(y/r)

Step 4: Simplify and solve for y
To get a Cartesian equation, multiply both sides by y:
r * y = 4
Since y = r * sin(θ), we can replace y with r * sin(θ):
r * (r * sin(θ)) = 4

Step 5: Replace r with x^2 + y^2
Since r^2 = x^2 + y^2, we can replace r in the equation:
(x^2 + y^2) * (y) = 4

Step 6: Identify the curve
This equation represents a curve in the Cartesian plane. By analyzing the equation, we can see that it's a semi-cubical parabola.

In conclusion, the Cartesian equation for the curve r = 4csc(θ) is (x^2 + y^2) * y = 4, and it represents a semi-cubical parabola.

The vector <-32, 44, 22> is parallel to the line of intersection of the two planes given by the equations 2x - 3y + 5z = 2 and 4x + y - 3z = 7.

To find a vector parallel to the line of intersection of the planes given by the equations 2x - 3y + 5z = 2 and 4x + y - 3z = 7, we first need to find the direction vector of the line of intersection.

We can find the direction vector by taking the cross product of the normal vectors of the two planes. The normal vector of the plane 2x - 3y + 5z = 2 is <2, -3, 5>, and the normal vector of the plane 4x + y - 3z = 7 is <4, 1, -3>. Taking the cross product of these two vectors, we get:

<2, -3, 5> × <4, 1, -3> = <-16, 22, 11>

This vector <-16, 22, 11> is the direction vector of the line of intersection of the two planes.

To find a vector parallel to this line, we can simply multiply the direction vector by a scalar. For example, we can choose a scalar of 2 to get:

2<-16, 22, 11> = <-32, 44, 22>

Therefore, the vector <-32, 44, 22> is parallel to the line of intersection of the two planes given by the equations 2x - 3y + 5z = 2 and 4x + y - 3z = 7.

Question 3: True

Beta (β) is indeed used to estimate the population proportion (p) when conducting hypothesis testing on a sample. Beta represents the probability of making a Type II error, which occurs when we fail to reject a null hypothesis that is actually false.
