Answer:

the domain of the function are {-3/2, 3/2, 3}

Step-by-step explanation:

f(x)=2x+1

range=-2, 4, 7

f(x)=-2

or, 2x+1=-2

or, x=-3/2

f(x)=4

2x+1=4

or, x=3/2

f(x)=7

2x+1=7

or, x=3

Answer:

A) sum = (180)(20) = 3600°

Step-by-step explanation:

The formula for the sum of interior angles for any polygon is (n-2) x 180° with n being the number of sides the polygon has.

We can just plug in 22 into the equation to get our answer:

(22-2) x 180°

= (20) x 180°

= 3600

Graph the line y=-3x-2
sashaice [31]

Answer:

The graph of the line is attached below.

Step-by-step explanation:

According to the slope-intercept form

y=mx+b

As the line equation  is given by

y=\:-3x\:-\:2\\

\mathrm{Slope\:of\:}-3x-2:\quad m=-3

y-intercept = b = -2

\mathrm{Axis\:interception\:points\:of}\:-3x-2:\quad \mathrm{X\:Intercepts}:\:\left(-\frac{2}{3},\:0\right),\:\mathrm{Y\:Intercepts}:\:\left(0,\:-2\right)

  • \mathrm{x-intercept\:is\:a\:point\:on\:the\:graph\:where\:}y=0

-3x-2=0:\quad x=-\frac{2}{3}

\mathrm{X\:Intercepts}:\:\left(-\frac{2}{3},\:0\right)

  • y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0

y=-3\cdot \:0-2:\quad y=-2\\

\mathrm{Y\:Intercepts}:\:\left(0,\:-2\right)

The graph of the line is attached below.

Evaluate using the trigonometric ratios Tan 60° + Cos 30° sin 60° + Cot 30° /CSC 30° Sec 30°<br>​
algol13

Answer:

(24 + 3√3) / 16.

Step-by-step explanation:

Tan 60° + Cos 30° sin 60° + Cot 30 /  csc 30 sec 30

= √3 + √3/2 * √3/2 + √3 /   2 * 2/√3

= 2√3 + 3/4 / 4/√3

= (8√3 + 3)/ 4 / √3

= 24 + 3√3 / 16
