Answer:

42 cm

Step-by-step explanation:

The first rectangle has a length of 4 and a Width of 7. the second rectangle has a length of 2 and a width of 7.

The formula for area of a rectangle is A=l*w

SO,

Rectangle 1: A= L*W

A=4*7

A=28

Rectangle 2:

A=L*W

A=2*7

A=14

Now, add both areas since they are both part of one whole recatngle.

28+14

= 42

Taking into account the definition of ratio and proportion, the airline should sell 440 tickets.

The ratio is the comparison of two quantities and is measured from the division of two values.

The relationship of equality that exists between two ratios, that is, between two comparisons between two determined quantities, is known as a proportion. So if [tex]\frac{a}{b}[/tex] corresponds to the ratio, then [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] equals a proportion.

An airplane flight has 374 seats. The probability that a person who buys a ticket actually goes on that flight is about 85%. The airline wants to fill all the seats (100%) on the flight.

This can be represented by the proportion:

[tex]\frac{374}{85}[/tex] = [tex]\frac{amount of tickets}{100}[/tex]

Solving:

amount of tickets= 100×[tex]\frac{374}{85}[/tex]

amount of tickets= 440

Finally, the airline should sell 440 tickets.

Given that ABCD is a parallelogram, the sum of its interior angles is:
360°

A parallelogram is a rectilinear two-dimensional figure with four sides whose opposite sides are parallel. See the image attached.

The sum of the exterior angles of any Triangle or any polygon is 360°. Hence, the sum of the exterior angles of CHFE (a polygon) is 360°.

The sides that are parallel to CE are:

FH

AD and

The side that are perpendicular to CE is side side HH, hence we can state that:

CE ⊥ EH, because both lines intersect each other at right angles.

Because the sum of angles in a triangle is 180° and we already have ∠CEH to be equal to ∠90° hence,

∠C + ∠H? = 180° - 90°

= 90°

The measure of the exterior angles of a regular pentagon is 72°

The quadrilateral RSTU be a parallelogram if opposite angles R and T are congruent to each other if x = 35 option first is correct.

It is defined as the four-sided polygon in geometry having four edges and four corners.

We have:

The angle measures of quadrilateral RSTU are shown.

m∠R = (2x)°

m∠S = (3x – 35)°

m∠T = (x + 35)°

If R and T are congruent:

2x = x + 35

x = 35 degree

Opposite angles R and T are congruent to each other if x = 35.

Thus, the quadrilateral RSTU be a parallelogram if opposite angles R and T are congruent to each other if x = 35 option first is correct.

Question 2.1.1

Reason:

Use the distance formula to find the distance from the origin (0,0) to the terminal point (-3, 4)

[tex](x_1,y_1) = (0,0) \text{ and } (x_2, y_2) = (-3,4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-(-3))^2 + (0-4)^2}\\\\d = \sqrt{(0+3)^2 + (0-4)^2}\\\\d = \sqrt{(3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]

The pythagorean theorem is a similarly related alternative path you can take.

This triangle is a 3-4-5 right triangle.

====================================================

Question 2.1.2

Reason:

r = distance from origin to terminal point

r = 5, calculated back in the previous problem above.

sin(alpha) = y/r = 4/5

cos(alpha) = x/r = -3/5

sin(alpha)+cos(alpha) = (4/5)+(-3/5) = 1/5

====================================================

Question 2.1.3

Reason:

Recall that tangent is the ratio of sine over cosine

tan = sin/cos

Therefore,

[tex]\tan(\alpha) *\frac{\cos(\alpha)}{\sin(\alpha)}\\\\\frac{\sin(\alpha)}{\cos(\alpha)}*\frac{\cos(\alpha)}{\sin(\alpha)}\\\\\frac{\sin(\alpha)*\cos(\alpha)}{\cos(\alpha)*\sin(\alpha)}\\\\1[/tex]

This assumes that neither sin(alpha) nor cos(alpha) are zero. Otherwise, we have a division by zero error.

The statement correctly describes the graph of y = ln(x - 7) + 3 is translated 3 units up as well as 7 units to the right.

The graph of a logarithmic function has a vertical asymptote at x = 0. The graph of a logarithmic function will decrease from left to right

if 0 < b < 1. And if the base of the function is greater than 1, b > 1, then the graph will increase from left to right.

Given graph : y = ln(x), has a vertical and horizontal translation.

As we know, y = ln(x - h) + k | where h is the vertical shift, and k is the horizontal shift.

Therefore, comparing y = ln(x - 7) + 3 it with different function we can write the graph of y = ln(x - 7) + 3 is translated 3 units up as well as 7 units to the right.

The rule for a rotation by 180° about the origin is (x,y)→(−x,−y).

Step-by-step explanation:

The rotation of angle 180 degree about origin is described below.

Rotation 180° about the origin is a geometric transformation that involves rotating a figure or shape around the point (0,0),

Also known as the origin, by an angle of 180 degrees.

This means that every point on the shape is moved to an equal distance away from the origin but on the opposite side of the origin.

This transformation is a reflection where the shape is flipped along,

the x-axis or y-axis or both, depending on the shape's orientation.

The rotation 180° about the origin is a common transformation in various geometrical applications, such as computer graphics, engineering, and physics.

It is a simple transformation that can be easily represented and performed using matrices or complex numbers.

Therefore,

rotation 180° about the origin is a geometric transformation that is important in various applications and involves rotating a shape around the origin by an angle of 180 degrees, resulting in a reflection of the shape across the x or y-axis.
