Answer:

Part a) AB=15\ cm

Part b) AB=11.1\ cm

Part c) AB=3/5\ cm

Part d) AB=3s\ cm

Step-by-step explanation:

see the attached figure to better understand the question

we know that

To find the length of the image after a dilation, multiply the length of the pre-image by the scale factor

Part a) we have

The scale factor is 5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(5)=15\ cm

Part b) we have

The scale factor is 3.7

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(3.7)=11.1\ cm

Part c) we have

The scale factor is 1/5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(1/5)=3/5\ cm

Part d) we have

The scale factor is s

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

3(s)=3s\ cm

Yancy has a board 25 feet long. He wants to cut the board into 4 1/2 foot lengths. Into how many 4 1/2 foot lengths can he cut i
seropon [69]
So first we would convert 4 1/2 foot lengths into a decimal.

4.5 feet

Now we divide 25 by 4.5

25 ÷ 4.5 = 5.5

So Yancy can cut the board into five 4 1/2 foot lengths because the question says how many can he cut.

Given that the base of the rock is 14 feet, and the height of the rock is 12 feet, what is the slope on which the vehicle is lea
ExtremeBDS [4]
Hi! So pretty much to find slope of a triangle you are going to use rise/run. The height being 12 and the length is 14. You get 12/14. Simplified is going to be 6/7. :)

We might choose to write a recursive formula rather than an explicit formula to define a sequence because (D) the sequence is strictly geometric.

<h3>What is a sequence?</h3>
  • A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important. It, like a set, has members (also called elements, or terms).
  • The length of the series is defined as the number of items (which could be infinite).
  • Unlike a set, the same components can appear numerous times in a sequence at different points, and the order does important.
  • Formally, a sequence can be defined as a function from natural numbers (the sequence's places) to the elements at each point.
  • The concept of a sequence can be expanded to include an indexed family, which is defined as a function from an index set that may or may not contain integers to another set of elements.

Recursive formulas are commonly used to compute the nth term of a sequence, where a(n) is the sum of all the preceding values.

Using its position, explicit formulas can compute a(n).

Therefore, we might choose to write a recursive formula rather than an explicit formula to define a sequence because (D) the sequence is strictly geometric.

Answer:

The answer to your question is:

x = 1

y = 1

z = 0

Step-by-step explanation:

                                -2x + 2y + 3z = 0             (1)

                                -2x - y + z = -3                  (2)

                                 2x + 3y + 3z = 5              (3)

Solve (1) and (2)  

Multiply 2 by 2

                                 -2x + 2y + 3z = 0

                                 -4x -2y   + 2z = -6

                                -6x          + 5 z = -6        (4)

Solve (2) and (3)

Multiply 2 by 3

                               -6x - 3y + 3z = -9

                                2x + 3y + 3z = 5

                               -4x         + 6z = -4           (5)

Solve (4) and (5)

Multiply (4) by 2 and (5) by -3

                           -12x    + 10 z = -12

                            12x    -  18z   = 12

                                         -6z = 0

                                          z = 0

Then

            -4x + 6(0) = -4

           -4x = -4

            x = -4/-4

            x = 1

Finally

                 -2(1) - y + (0) = -3      

                -2 - y = -3

                 -y = -3 + 2

                 y = 1
