Answer:

That is asking you to find the sine of (3/4) PI radians.

If you look at the attached graphic, you will see that (3/4) PI radians = 135 degrees

Going to this calculator, we see that the sine of 135 degrees is 0.70711

Which best describes the complement of spinning any number less than 3?
tatuchka [14]

Answer:

  • <u>The complement of spinning any number less than 3, is spinning a number equal to or greater than 3.</u>

Explanation:

The complement of a subset is the subset of elements that are not in the given subset.

You must know which numbers the spinner has.

Assuming the spinner has the numbers 1, 2, 3, 4, the complement of spinning any number less than 3, is spinning a number that is not less than 3.

Then, that is spinning a number that is equal to or greater than 3.

The numbers that are equal to  or greater than four, for a spinner that has the numbers 1, 2, 3, and 4 are 3 and 4.

Thus, the complement of spinning any number less than 3 is spinning a three or a four.

What is the equation of the line shown in this graph? <br><br>any links will be reported<br><br>​
Blizzard [7]

Answer:

y = 1

Step-by-step explanation:

Slope is written in the form y=mx+b. Where m is the slope and b is the y-intercept.

When there isn't a slope, as in the line is flat and it isn't moving up or down, you wouldn't write anything for it. You would just write y equals the y-intercept (y = b).

Likewise, if the y-intercept is at (0,0), then you'd only write y equals the slope (y = mx).

Hopefully this makes sense :)

Btw, I also answered in the main comments earlier, so you can check that out as well.

Without calculating, how do you know that the equation |4x - 71 = -1 has no solution?
Anni [7]

Answer:

See Explanation

Step-by-step explanation:

Given

|4x - 7| = -1

Required:

How do you know, it has no solution

The expression on the left-hand side is an absolute function and the result is always positive.

However, the expression on the right-hand side shows a negative sign.

The negative sign is on the contrary to what an absolute value represent.

<em></em>

<em>Hence, it has no solution.</em>
