Which graph represents the function below?
Andrei [34K]
Plug it into a graphing calculator, I used Desmos. 

The graph is the same as x=-2 and y=-4. All I did was replace g(x) with y since y is the output function and so is g(x), then I just added the whole expression as follows and it graphed it for me. 

The bottom graph to the left is the answer.

I hope this helps!

If I have a line that starts at the origin (0,0), and goes 13 meters at an angle of π/6 in the standard position (ie. 30° north
Klio2033 [76]

Line goes 11.2583303 meters in the x direction (east) and 7.5 meters in the y direction (north) .

<u>Step-by-step explanation:</u>

Here we have , If I have a line that starts at the origin (0,0), and goes 13 meters at an angle of π/6 in the standard position (i.e. 30° north of east) . We need yo find how far does it go in the y direction (north), and how far does it go in the x direction (east). Let's find out:

According to question we have a right angle triangle as :

Hypotenuse =13m\\x=\frac{\pi}{6} =30

x direction (east)

We know that ,

⇒ cosx = \frac{Base}{Hypotenuse}

⇒ cos30 = \frac{Base}{13}

⇒ \frac{\sqrt{3} }{2} = \frac{Base}{13}

⇒ Base=\frac{\sqrt{3}(13) }{2} m

⇒ Base=11.2583303m

y direction (North )

We know that ,

⇒ sinx = \frac{Perpendicular}{Hypotenuse}

⇒ sin30 = \frac{Perpendicular}{13}

⇒ \frac{1}{2} = \frac{Perpendicular}{13}

⇒ Perpendicular=7.5m

Therefore , Line goes 11.2583303 meters in the x direction (east) and 7.5 meters in the y direction (north) .

Find the area of a composite shape below. Really confused on this one. can i get a step by step explanation please :) &lt;3
Kaylis [27]

Answer:

390 ft^2

Step-by-step explanation:

We will break this shape into two rectangles, one that is 7 ft wide by 30 ft long

and the other that is 25ft-7ft wide by 30ft -20 ft  long  (18 ft by 10 ft)

1st:  7 ft by 30 ft

A = l*w = 7*30 = 210 ft^2

2nd:  18 ft by 10 ft

A = l*w = 18 * 10 = 180 ft^2

Add the areas together

210+180 = 390 ft^2
