Answer:

The correct option is c.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of vertices G and H are  G(-4,3) and H(-2,5).

Rotation 90° about the origin in the counterclockwise direction is defined as

(x,y)\rightarrow (-y,x)

After rotation the coordinates of G and H are

G(-4,3)\rightarrow G'(-3,-4)

H(-2,5)\rightarrow H'(-5,-2)

Therefore the coordinates of G and H after rotation are (-3,-4) and (-5,-2). So, option c is correct.

Olegator [25]

Answer:

f(-3) = -16

Step-by-step explanation:

Given piecewise function is,

f(x) = 5x - 1       If x < -2

        x + 3       If x ≥ -2

We have to find the value of he function when x = -3

Since x = -3 is less than x = -2,

Piece of the function to be considered,

f(x) = 5x - 1

f(-3) = 5(-3) - 1

f(-3) = -16

Which are solutions to 3sin^2 θ - 2sin θ = 0, 90°≤θ≤90°
jeka57 [31]

Answer:

The solutions of the equation are -41.8° , 0.0° , 41.8°

Step-by-step explanation:

∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function

∵ The domain of the function is -90° ≤ Ф ≤ 90°

- Lets take sinФ as a common factor

∴ sinФ (3 sinФ - 2) = 0

- Two terms multiplied by each other = 0

∴ One of them must be equal zero

∴ sinФ = 0 or 3 sinФ - 2 = 0

- If sinФ = 0 ⇒ Ф = 0.0°

- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3

∵ sinФ 2/3

∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)

∵ -90° ≤ Ф ≤ 90°

∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)

∴ The solutions of the equation are -41.8° , 0.0° , 41.8°
