Answer:

insufficient information7.2 miles18.5 miles

Step-by-step explanation:

1. Insufficient information. We need to know the direction of one observer from the other, and the reference for the angles being measured.

__

2. See the first attachment. The law of sines tells you the distance r is ...

   r = s(sin(R)/sin(S))

The angle at S is the supplement of the sum of the given angles:

  ∠S = 180° -35° -45° = 100°

Then the distance is ...

  r = (10 mi)sin(45°)/sin(100°) = 7.1802 mi

The distance from Juan to the ship is about 7.2 miles.

__

3. See the second attachment. The law of sines tells you the distance 'a' is ...

  a = b(sin(A)/sin(B))

  a = (10 mi)sin(45°)/sin(50°) ≈ 18.4612 mi

The distance from airplane B to the airport is about 18.5 miles.

Step-by-step explanation:

Hope it helps

A. Distribute:

=(x)(x)+(x)(−3)+(2)(x)+(2)(−3)

=x2+−3x+2x+−6

Combine Like Terms:

=x2+−3x+2x+−6

=(x2)+(−3x+2x)+(−6)

=x2+−x+−6

B. I can't find an explanation

C.  I can't find an explanation

Answer:

So we apply the distributive property to get

a) x^2 - 3x + 2x - 6

b) 2x^2 - 8x - 3x + 12

c) x^2 - 2x + 2x - 4

then we add like terms to get

a) x^2 - x - 6

b) 2x^2 - 11x + 12

c) x^2 - 4

22. B1, G1 (from left to right)

23. E5

Step-by-step explanation:

A farmer has 100 acres on which to plant two crops. The cost of planting the first crop is $20 per acre and the second crop is $40 per acre, and up to $3000 is available to cover the cost of planting. Each acre of the first crop will require 5 work-hours for harvesting and each acre of the second crop will require 20 work-hours. The farmer can rely on having only a total of 1350 work-hours for harvesting the two crops. If the profit is $100 per acre for the first crop and $300 per acre for the second crop, determine the acreage that should be planted with each crop in order to maximize the total profit.

Which of the following polygons has five lines of symmetry?
O A. Equilateral triangle
OB. Regular heptagon
O C. Regular pentagon
O D. Square

Answers

Answer:

pentagon have 5 sides, 5 symmetry lines.

So your answer is Option C.

The polygon with five lines of symmetry is a regular pentagon.

Option B is the correct answer.

What are regular polygons?

A regular polygon is a closed shape that has straight sides of equal length and interior angles of equal measure.

This means that all of the sides and angles of a regular polygon are congruent (i.e., have the same size).

We have,

A regular pentagon is a five-sided polygon where all sides and angles are equal. It has five lines of symmetry, which means it can be divided into five congruent parts through lines that reflect the polygon onto itself.

To see why a regular pentagon has five lines of symmetry, consider drawing lines from each vertex to the center of the pentagon.

These lines divide the pentagon into five isosceles triangles, each with two equal sides and two equal angles.

Each of these triangles has a line of symmetry that passes through its vertex opposite to the equal sides, and through the midpoint of the base.

Thus,

The regular pentagon has five lines of symmetry.
