The dependent variable is the output of a function, which would be the Y value.


In the given set: (2,3) (2,-2) (-4,-2) (-2,2), the Y value is the 2nd number inside each pair of parenthesis.


The answer would be D. {–2, 2, 3}

find the perimeter of a square if the length of its diagonal is 16 millimeters. round to the nearest tenth.
bekas [8.4K]

Answer:

45.3 mm

Step-by-step explanation:

Use the basic 45-45-90 triangle with side length 1 as the building block here.  If the length of one side is 1, then the perimeter is 1 + 1 + 1 + 1, or 4, and the length of the diagonal is √2.

We are told that the length of the diagonal of the given square is 16 m.

Determine the length of one side of this square, using an equation of proportions:

 16        x

------ = -------

 √2       1

                                             16

Then (√2)x = 16, and x = -----------

                                             √2

The perimeter of the given square (with diagonal 16 mm)  is 4 times the side length found above, or:

      16                      16

4 ---------- = (2)(2) -----------  =  (2)(√2)(16) = 32√2 (all measurements in mm)

       √2                    √2

This perimeter, rounded to the nearest tenth, is 45.3 mm.

a construction worker has rope 9 m long he needs to cut it in pieces that are each 3 /5 m long how many such pieces can he cut w
lapo4ka [179]

Dividing a whole number and an improper fraction seems tricky, but it just has one or two more steps than the normal process.  First, convert the whole number "9" into a fraction by giving it a denominator of "1".  It should look like 9/1.  Now that both numbers are converted into like formats (improper fractions), you should have 9/1 divided by 5/3.

Second, flip 5/3 over into 3/5 - this is the "reciprocal". Now you have 9/1 divided by 3/5.  It's just a matter of multiplying across the math sentence.  Multiply the numerators (9x3) and the denominators (1 x 5).  Your new fraction should be 27/5.  This is your answer in the improper fraction format.

You can create other formats depending on the expected answer.  For a mixed number, "divide your fraction UP" (27 divided by 5) which gives you 5 and 2/5.  This can be further converted into 5.4 if you need your answer in decimal form.

Insert three arithmetic means between 4 and 10.
Bumek [7]

Answer:

5.5, 7, 8.5

Step-by-step explanation:

Find the mean of 4 and 10, that is

\frac{4+10}{2} = \frac{14}{2} = 7

Now repeat with 4 and 7 and 7 and 10

\frac{4+7}{2} = \frac{11}{2} = 5.5

\frac{7+10}{2} = \frac{17}{2} = 8.5

Hence

4, 5.5, 7, 8.5, 10 ← is an arithmetic sequence with d = 1.5
