Answer:

1) The stars are not constant in their position.

2) No. The stars aren't in original position because of apparent movement of stars in the sky.

3) Due to rotation of earth on its axis , the stars appear to move from west to east in the sky. Actually stars don't move as they are constant in their position but they appear to move with respect to earth.

4) Both the motion of stars & motion of sun are similar because both are an example of apparent motion. Both appear to change their respective positions but in reality , sun & stars are constant in their positions. But as earth is rotating , it appears like sun & stars are changing their positions.

Rewrite in simplest terms: -10(-v+6w)-w-9(-3w-v)−10(−v+6w)−w−9(−3w−v)

spayn [35]

The simplest form of the expression is -10 + 8v + 32w

Given the expression

-10(-v+6w)-w-9(-3w-v)

First, we need to expand the given equation using the distributive law:

-10(-v+6w)-w-9(-3w-v)

= -10-v+6w-w-9(-3w)+9(v)

= -10-v+6w-w+27w+9v

Collect the like terms:

= -10 - v +9v + 6w - w+ 27w

= -10 + 8v + 32w

Hence the simplest form of the expression is -10 + 8v + 32w

REASONING An even integer can be represented by the expression $2n$ , where $n$ is any integer. Find three consecutive even inte

san4es73 [151]

Answer:

First Integer = 16

Second Integer = 18

Third integer = 20

Step-by-step explanation:

An even integer is represented by 2n

Where n is any integer

Let :

First Integer = 2n - 2

Second Integer = 2n

Third integer = 2n + 2

The sum of three even consecutive numbers = 2n - 2 + 2n + 2n + 2

= 2n + 2n + 2n - 2 + 2 = 54

= 6n = 54

n = 54/6

n = 9

First Integer = 2n - 2 = 2(9) - 2

= 16

Second Integer = 2n = 2(9)

= 18

Third integer = 2n + 2 = 2(9) + 2

= 20

1. The length of the base of an isosceles triangle is y. The length of a leg is 3y+2. The perimeter of the triangle is 46. Find

belka [17]

Step-by-step explanation:

Length of the base = y

Length of a side = 3y + 2

Length of the third side= 3y + 2 (Isosceles triangle)

Perimeter = Sum of all sides

46 = y + 3y + 2 + 3y + 2

46 = y + 2(3y +2)

46 = y + 6y + 4

46 = 7y + 4

46 - 4 = 7y

42 = 7y

42/7 = y

6 = y

Therefore, the length of the base is 6
