Which situation represents a proportional ralationship

1 answer:

6 0

A situation represents a proportional relationship if you can write equivalent ratios of related quantities in that situation.

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

The proportional relationships can be represented in many ways:

i) One way is considering a straight line graph passing through the origin.

ii) A verbal description describing the directly proportional relationship between two quantities.

iii) An equation y=kx, here k= constant of proportionality.

For example:

1/2 and 5/10 have a proportional relationship

Both of them are same.

The proportional relationship can help in dealing with the real life problems. Some of them are scaling a diagram, adjusting a recipe and finding increase/decrease in percentage.

What ate the domain and range of f(x)(1/6)x+2?

never [62]

Answer:

Domain : all real numbers

Range: All numbers greater than 2

Step-by-step explanation:

The shark. (Haha, I'm sorry.)

There are no restrictions on the x. X can be any real number.

The range, however, does have restrictions. The range has to be a number greater than 0.

Why?

Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.

Answer:

Option A ( -3/2 , $\frac{-3\sqrt{3} }{2}$ )

Step-by-step explanation:

According to Question, The Spinner Rotate 600* Thus after Completing 360* it Comes Exactly Where It Started . Now again rotate It 180* .

Now We Are on ( -X axis ) & Completed 360*+180*=540* Rotation

Now After Rotate It 60* More we come in Third Quadrant & Here In Third Quadrant Only Tangent & Cotangent Is Positive .(Sine & Cosine is Negative)

(For Diagram, Please Find in attachment)

Now In Triangle OAB

Cos60* = OA / OB

1/2 = -X / 3 Thus X= -3/2

Sin60* = AB / OB

$\sqrt{3}$ /2 = -Y / 3 Thus Y = - $\sqrt{3}$ * 3 /2
