Domain is basically the x value and the range is the y value. Domain is also known as the input and range is known as the output.

The domain refers to the x values of a function. The range refers to the y values. In a linear equation such as y=2x, for example, the domain would be negative infinity to positive infinity.

[-∞, <span>∞]

The range would be the same. However, for certain equations such as most parabolas, the range of a function (the vertical limits) are not infinite.</span>

URGENT PLEASE HELP 98 POINTS Find the direction angle of vector v to the nearest tenth of a degree.

zlopas [31]

Answer:

The direction angle of vector v is equal to $9.5\°$

Step-by-step explanation:

Let

$A(-5,0),B(7,2)$

The vector v is given by

$v=B-A$

$v=(7, 2) - (-5, 0)$

$v=((7 - (- 5)), (2-0))$

$v=(12, 2)$

Remember that

The direction angle of the vector is equal to

$tan (\theta) =\frac{y}{x}$

substitute the values

$tan (\theta) =\frac{2}{12}$

$\theta=arctan(\frac{2}{12})=9.5\°$

yuri has a rope 12 meters long. he cuts it into pieces that are each 2 meters long. what fraction of the rope is one piece

Lelu [443]

So the numerator of your fraction (the top number) is the amount that was cut. The denominator (the bottom number) is the total amount of rope. So, your fraction would be 2/12. You can still simplify that by dividing both the numerator and denominator by 2 and end up with 1/6. Does that make sense? If you need any more help, go ahead and message me :)
