The following equation involves a trigonometric equation in quadratic form. Solve the equation on the interval [0,2π).

Effectus [21]

Answer:

$\dfrac{\pi}{6}, \dfrac{5\pi}{6}, \dfrac{3\pi}{2}$

Step-by-step explanation:

Given the quadratic equation as:

$2sin^2x+sinx=1\\OR\\2sin^2x+sinx-1=0$

Let us put $sinx=y$ for simplicity of the equation:

Now, the equation becomes:

$2y^2+y-1=0$

Now, let us try to solve the quadratic equation:

$\Rightarrow 2y^2+2y-y-1=0\\\Rightarrow 2y(y+1)-1(y+1)=0\\\Rightarrow (2y-1)(y+1)=0\\\Rightarrow 2y-1 = 0, y+1 = 0\\\Rightarrow y = \dfrac{1}{2}, y = -1$

So, the solution to the given trigonometric quadratic equation is:

$sinx = \dfrac{1}{2}$

and

$sinx=-1$

Let us try to find the values of $x$ in the interval $[0, 2\pi)$ .

$sin\theta$ can have a value equal to $\frac{1}{2}$ in 1st and 2nd quadrant.

So, $x$ can be

$30^\circ, 150^\circ\\OR\\\dfrac{\pi}{6}, \dfrac{5\pi}{6}$

For $sinx=-1$ ,

$x = 270^\circ\ or\ \dfrac{3 \pi}{2}$

So, the answer is:

$\dfrac{\pi}{6}, \dfrac{5\pi}{6}, \dfrac{3\pi}{2}$

What are the amplitude, period, phase shift, and midline of f(x) = −3 sin(4x − π) + 2? (6 points)

algol [13]

The parent function of $y=-3sin(4x- \pi )+2$ is $y=sin(x)$

The diagrams below show step by step transformation

As we can see from the graph $y=-3sin(4x- \pi )+2$ , the amplitude of the function is 3, period of $\frac{ \pi }{2}$ , phase shift of π and midline y=2

Which of the following firms could raise prices and expect an increase in revenues?

Katena32 [7]

Answer:

b. a firm whose product has an elasticity of 0.31

Step-by-step explanation:

A type of product that has elasticity less than 1 is considered as 'inelsatic goods. Inelastic goods would not have a decrease in demand even if they are increasing the price of their product.

This means that when the producer of this product increase the price, their profit will either stay stagnant or increase.

In most cases, products that are very crucial to fulfill our basic needs or day to day activity have this type of elasticity.

Example : Water and Gasoline,
