The point A(-8, 6) is translated using T: (x,y) → (x + 5. y - 4). What is the distance from A to A'?
Vsevolod [243]
Translated means the points are moving across the plane without rotating or changing shape. In this case, the x-coordinate would be moving up 5 (x + 5) and the y-coordinate would be moving to the left 4 (y - 4).

A is (-8, 6). A' is the result of the translation from this point. The results of the solution above in A is the point (-3, 2) = A'.

Now you must find the distance between these two coordinates. To find the distance you must use the distance formula: √<span>(x2 - x1)^2 + (y2 - y1)^2. Since you now have two points, A and A', plug these into the distance formula.

</span>√(-3 - (-8))^2 + (2 - 6)^2
√5^2 + (-4)^2
√25 + 16
√41

The distance from A to A' is √41.

1.The coordinates of the vertices of △RST are R(−4, −1) , S(−1, −1) , and T(−4, −2) .
Tju [1.3M]

RS points east; R'S' points north, so there has been a rotation 90° CCW.

After that rotation, point S would be at (1, -1). It is actually at (1, 1), so has been shifted 2 units upward.

A sequence that does the desired mapping is

  • c. rotation of 90° CCW about the origin
  • b. translation 2 units up

Answer:

B) -5, -2.4, 20%, sqrt(9), 3pi

Step-by-step explanation:

sqrt(9) = 3

3pi = 3 * 3.14 = 9.42

20% = 0.2

Find the cumulative frequency
aleksandrvk [35]

We get the cumulative frequency as:

                3

                7

               13

               22

               29

               36

               37

We are given the data:

Daily Low(°F)    Frequency

 35 - 39                    3

 40 - 44                    4

 45 - 49                    6

 50 - 54                    9  

 55 - 59                    7

 60 - 64                    7

 65 - 69                     1

We have to find the cumulative frequency of the data.

We will do this by adding the data values of previous interval.

Daily Low(°F)    Frequency     cumulative frequency

 35 - 39                    3                              3

 40 - 44                    4                              7

 45 - 49                    6                             13

 50 - 54                    9                             22

 55 - 59                    7                             29

 60 - 64                    7                             36

 65 - 69                    1                              37

Therefore, we get the cumulative frequency as:

                3

                7

               13

               22

               29

               36

               37
