¿Cuál es el resultado de la multiplicación de los números complejos z1*z2 expresados en su forma polar, z1= 230° y z2= 540°?

The function given in the table is an exponential function.

The function given in the table is clearly not linear, since the y value is changing rapidly.

Here we can see that the function value is changing as the multiplication of 7.

y = 7⁰ = 1, when x = 1

y = 7¹ = 7, when x = 2

y = 7² = 49, when x = 3

y = 7³ = 343, when x = 4

y = 7⁴ = 2401, when x = 5

So here the equation of the function can be written as,

y = 7ˣ⁻¹

Here the variable x is in the exponent.

So it is an exponential function.

Hence the given function is an exponential function.

The exact value for the trigonometric function of numbers is derived to be √3/2.

Trigonometric identities are equations that involve the trigonometric functions (such as sine, cosine, tangent, cosecant, secant and cotangent) and are true for all possible values of the variables involved. These identities can be used to simplify trigonometric expressions, solve equations, and prove other mathematical statements.

Then sum and difference identities states that:

sin(A ± B) = sinAcosB ± cosAsinB

cos(A ± B) = cosAcosB ∓ sinAsinB

so;

sin(11°) cos(49°) + cos(11°) sin(49°) = sin(11 + 49)

sin(11°) cos(49°) + cos(11°) sin(49°) = sin(60°)

sin(11°) cos(49°) + cos(11°) sin(49°) = √3/2.

Therefore, the exact value for the trigonometric function of numbers is derived to be √3/2.

The resistance of 1800 feet of the same sort of wire with a 0.45in diameter is roughly 15037.45 ohms.

Let R be the resistance of the wire,

L be the length of the wire,

d be the diameter of the wire, and

k be a constant of variation.

Then we have the equation:

R = k * L / d^2

Solving for k to find the resistance of a wire of varying length and diameter.

We can create an equation using the information provided:

15611 = k * 700 / 0.2^2

Solving for k, we get:

k = 15611 * 0.2^2 / 700

k ≈ 0.1799

Using k to calculate the resistance of a wire with a length of 1800 feet and a diameter of 0.45 inches:

15037.45 ohms = 0.1799 * 1800 / 0.452 R

The probability of a random point which is located on  AK  will be present on BE is equal to 0.3.

From the attached figure we have,

On the number line point A is located at -10.

And on the same number line point K is at 10.

Distance between AK = ( 10 ) - ( -10 )

⇒ Distance between AK = 10 + 10

⇒ Distance between AK = 20

Now, on the same number line location of point B is -8.

And location of point E is -2.

Length of BE = ( -2 ) - ( -8 )

The solution to the system of inequalities 2x − y < 4 and x + y < −1 is the intersection of the shaded regions below the lines 2x - y = 4 and x + y = -1, labeled AB on the graph. Regions A and B represent the solutions to each individual inequality.

To solve the system of inequalities 2x − y < 4 and x + y < −1, we can use the following steps

Solve each inequality for y in terms of x

2x - 4 < y

-x - 1 < y

Plot the boundary lines for each inequality as dotted lines. To do this, we can use the equality signs instead of the inequality signs.

2x - 4 = y

-x - 1 = y

Shade the region that satisfies each inequality. To do this, we can test a point that is not on the boundary line in each inequality. For example, we can test (0,0) in the first inequality

2(0) - 0 < 4

0 < 4

Since (0,0) satisfies the first inequality, we shade the region below the line 2x - y = 4. Similarly, we can test (0,-2) in the second inequality

(0) + (-2) < -1

-2 < -1

Since (0,-2) satisfies the second inequality, we shade the region below the line x + y = -1.

The solution to the system of inequalities is the intersection of the shaded regions, which is labeled AB in the graph. The shaded region labeled AB is the region that satisfies both inequalities, which is the region below both lines.

In this diagram, A represents the launch pad, B represents the maximum altitude of the rocket, C represents the position of the photographer, and θ represents the angle at which the tripod should be set.

We want to find θ.

First, we can find the height of the triangle ABC using the Pythagorean theorem:

AB² = AC² + BC²

200² = AC² + 50²

AC² = 200² - 50²

AC = √(200² - 50²)

AC = 190.526 ft

Next, we can use the tangent function to find θ:

tan(θ) = opposite/adjacent = AB/BC = 200/50 = 4

Taking the arctangent of both sides, we get:

θ = [tex]tan^{-1}(4)[/tex]

θ = 75.96 degrees

The surafce area of the cone with a slant height of 14 in and a diameter of 6 in is 160.2 in².

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The surface area of a cone can be expressed as;

SA = πrl + πr²

Where r is radius of the base, l is the slant height of the cone and π is constant pi.

Given that:

Slant height l = 14 in

Diameter d = 6 in

Radius r = diameter/2 = 6/2 = 3in

S.A = ?

Plug the given values into the above formula and solve for the surface area.

SA = πrl + πr²

SA = ( π × 3in × 14in ) + ( π × (3in)² )

SA = 160.2 in²

Answer:

To calculate the area of the shaded shape, we need to first find the area of the two rectangles and then subtract the overlap.

The area of the rectangle with dimensions 5m and 13m is:

Area = 5m x 13m = 65 square meters

The area of the rectangle with dimensions 9m and 11m is:

Area = 9m x 11m = 99 square meters

To find the overlap, we need to calculate the width of the shaded region. We can do this by subtracting the length of one rectangle from the other:

13m - 9m = 4m

So the width of the shaded region is 4m.

Now we can find the area of the shaded region by multiplying the width by the length:

Area = 4m x 5m = 20 square meters

Finally, we can find the total area by subtracting the overlap from the sum of the two rectangle areas:

Total Area = (65 + 99) - 20 = 144 square meters

Therefore, the area of the shaded shape is 144 square meters.

a) y = -2x + 3

b) y = -3x + 7

c) y = -1/2x + 4

d) y = 2

Step-by-step explanation:

Gradient is also known as slope

a) y = mx + b

3 = (-2)0 + b

b = 3

y = -2x + 3

b) y = mx + b

1 = (-3)(2) + b

1 = -6 + b

b = 7

y = -3x + 7

c) Slope m = (y2 - y1)/(x2 - x1)

m = (2 - 3)/(4 - 2) = -1/2

y = mx + b

3 = -1/2(2) + b

3 = -1 + b

b = 4

y = -1/2x + 4

d) The x‐axis or any line parallel to the x‐axis has a slope of 0.

y = mx + b

2 = -3(0) + b

b = 2

y = 2

Answer:

a) The equation of this line is y = -2x + 3

b) The equation of this line is y = -3x + 7

c) The equation of this line is y = -1/2x + 4 or y = -0.5x + 4

d) The equation of this line is y = 2

Step-by-step explanation:

The equation of a line can be written in the form y = mx + c, where m is the gradient and c is the y-intercept.

a) The equation of the line with a gradient of -2 and cutting the y-axis at 3 can be found using the point-slope form of a linear equation. The point-slope form is given by y - y1 = m(x - x1), where m is the gradient and (x1, y1) is a point on the line. Substituting m = -2 and (x1, y1) = (0, 3), we get:

y - 3 = -2(x - 0)

Simplifying the right-hand side gives:

y - 3 = -2x

Adding 3 to both sides gives the final equation:

y = -2x + 3

b) The equation of the line with a gradient of -3 and passing through the point (2, 1) can be found using the point-slope form again. Substituting m = -3 and (x1, y1) = (2, 1), we get:

y - 1 = -3(x - 2)

Simplifying the right-hand side gives:

y - 1 = -3x + 6

Adding 1 to both sides gives the final equation:

y = -3x + 7

c) To find the equation of the line passing through the points (2, 3) and (4, 2), we first need to find its gradient. The gradient is given by:

m = (y2 - y1)/(x2 - x1)

Substituting the coordinates of the two points, we get:

m = (2 - 3)/(4 - 2) = -1/2 or -0.5

Now, we can use the point-slope form again, this time with (x1, y1) = (2, 3) and m = -1/2:

y - 3 = (-1/2)(x - 2)

Simplifying the right-hand side gives:

y - 3 = (-1/2)x + 1

Adding 3 to both sides gives the final equation:

y = (-1/2)x + 4 or y = -0.5x + 4

d)The line is parallel to the x-axis and passes through the point (-3 ; 2). A line parallel to the x-axis has a gradient of 0. The general equation of a line is y = mx + c, where m is the gradient and c is the y-intercept. Since the gradient is 0, the equation becomes y = c. Since the line passes through the point (-3 ; 2), we can substitute y = 2 into the equation to find that c = 2. Therefore, the equation of this line is y = 2.

The value of x after solving the given equation (6x+30) = 2x is equal to -7.5.

To solve for x in the equation (6x+30) = 2x, we need to isolate x on one side of the equation.

First, we can simplify the equation by subtracting 2x from both sides:
