So these.

1 pound of peanut costs 2.50

5 pounds of peanuts costs 12.50

The point (4,10) is also on the line

I believe I got all these right. I had a worksheet/ pre-assesment on this and I got 100. So I think this is right. My calculator also agrees.

CAN SOMEONE PLS TELL ME DOMAIN AND RANGE
lorasvet [3.4K]

Answers:

  • Domain is (-4, 3]
  • Range is (-5, 5]

=====================================================

Explanation:

The domain is the set of allowed x input values, aka the set of all allowed x coordinates of the points. We see that -4 < x \le 3. It might help to draw vertical lines through the endpoints until you reach the x axis. Note the open hole at x = -4 to indicate we do not include this as part of the domain (hence the lack of "or equal to" for the first inequality sign).

The interval -4 < x \le 3 then can be condensed into the shorthand form (-4, 3] which is the domain in interval notation.

It says: x is between -4 and 3. It can't equal -4 but it can equal 3.

So the use of parenthesis versus square brackets tells the reader which endpoint is included or not.

--------------------------------------------------

The range describes all possible y outputs. We see that y = 5 is the largest it gets and y = -5 is the lower bound. It might help to draw horizontal lines through the endpoints until you reach the y axis. The open hole means -5 is not part of the range.

The range as a compound inequality is -5 < y \le 5. This condenses into the shorthand of (-5, 5] which is the range in interval notation.

Verbally, the range is the set of y values such that y is between -5 and 5. It can't equal -5 but it can equal 5.

Use the unit circle tan (3/4)
Mariana [72]

Using the unit circle, the coordinates of 3π/4 is :

(-\frac{\sqrt[]{2}}{2},\frac{\sqrt[]{2}}{2})

Note that tangent function can be solved using the formula y/x

where x and y are the coordinates of the angle.

This will be :

\frac{\sqrt[]{2}}{2}\div(-\frac{\sqrt[]{2}}{2})=-1

The answer is -1
