Answer:

the graph in the attached figure

Step-by-step explanation:

we have

7x+3y

isolate the variable y

Subtract 7x both sides

3y

3y

Divide by 3 both sides

y

The solution of the inequality is the shaded area below the dashed line

The equation of the shaded line is y=-4x+2

The slope of the dashed line is negative m=-4

The y-intercept of the dashed line is the point (0,2)

The x-intercept of the dashed line is the point (0.5,0)

To graph the inequality plot the intercepts and shade the area below the dashed line

using a graphing tool

the graph in the attached figure

f\left(\dfrac\beta2\right)=\sin\dfrac\beta2

Recall the half-angle identity:

\sin^2\dfrac\beta2=\dfrac{1-\cos\beta}2\implies\sin\dfrac\beta2=\pm\sqrt{\dfrac{1-\cos\beta}2}

So in order to find f\left(\dfrac\beta2\right), we only need to know the value of \cos\beta. But there are two possible values. To decide which to take, we use the given information: we know that \beta lies in quadrant III, which means \pi, so \dfrac\pi2, which places \dfrac\beta2 in quadrant II. In this quadrant, the sine of angle is positive, and so

\sin\dfrac\beta2=\sqrt{\dfrac{1-\cos\beta}2}

\beta is an angle of a ray whose terminal point, \left(-\dfrac13,y\right) lies on the circle x^2+y^2=1. The x-coordinate is all we need to know in order to find that \cos\beta=-\dfrac13. So,

\sin\dfrac\beta2=\sqrt{\dfrac{1-\left(-\frac13\right)}2}=\sqrt{\dfrac46}=\dfrac{\sqrt2}{\sqrt3}=\dfrac{\sqrt6}3
