Answer:

Step-by-step explanation:

The max value of the sine function is 1.

If we multiply it by 2, we get 2 sin x, whose max. value is 2.

If we multiply the sine function by -2, the max value of this functin is still 2.

Please solve this problem because tomorrow is my exam.

jonny [76]

Step-by-step explanation:

a). A = {x ∈ R I 5x-8 < 7}

5x - 8 < 7 <=> 5x < 8+7 <=> 5x < 15 =>

x < 3 => A = (-∞ ; 3)

A ∩ N = {0 ; 1 ; 2}

A - N* = (-∞ ; 3) - {1 ; 2}

b). A = { x ∈ R I 7x+2 ≤ 9}

7x+2 ≤ 9 <=> 7x ≤ 7 => x ≤ 1 => x ∈ (-∞ ; 1]

A ∩ N = {0 ; 1}

A-N* = (-∞ ; 1)

c). A = { x ∈ R I I 2x-1 I < 5}

I 2x-1 I < 5 <=> -5 ≤ 2x-1 ≤ 5 <=>

-4 ≤ 2x ≤ 6 <=> -2 ≤ x ≤ 3 => x ∈ [-2 ; 3]

A ∩ N = {0 ; 1 ; 2 ; 3}

A - N* = [-2 ; 3) - {1 ; 2}

d). A = {x ∈ R I I 6-3x I ≤ 9}

I 6-3x I ≤ 9 <=> -9 ≤ 6-3x ≤ 9 <=>

-15 ≤ -3x ≤ 3 <=> -5 ≤ -x ≤ 3 =>

-3 ≤ x ≤ 5 => x ∈ [-3 ; 5]

A ∩ N = {0 ; 1 ; 2 ; 3 ; 4 ; 5}

A - N* = [-3 ; 5) - {1 ; 2 ; 3 ; 4}

A decagon with points labeled a through j clockwise. point a is the top left point. if this regular decagon is rotated countercl

serg [7]

The e vertex of the decagon will be in the top position after rotating it counterclockwise by 3 times the smallest angle of rotation.

Which vertex will be in the top position of the regular decagon?

A regular decagon has 10 sides of equal lengths with points labeled 'a' through 'j' clockwise. It is given that the point a is the top-left point. Hence, the the vertex which is in the the top position currently is 'b'.

Now, the smallest angle of rotation will be the angle between the two sides of the decagon.

In the first rotation by the smallest angle in counterclockwise direction, point 'c' will come to the top position. In the second rotation by the smallest angle in counterclockwise direction, point 'd' point will become the top most vertex. Finally, after the third similar rotation, 'e' vertex will be in the top position of the decagon. (Refer the attached diagram)
