XYZ has coordinates X(2, 3), Y(1,4), and Z(8,9). A translation maps X to X'(4,7). What are the coordinates for Y' and Z' for thi

Rashid [163]

Answer:

The coordinates are $Y'(x,y) = (3, 8)$ and $Z'(x,y) = (10, 13)$ .

Step-by-step explanation:

First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:

$X'(x,y) = X(x,y) + T(x,y)$ (1)

Where $T(x,y)$ is the vector translation.

If we know that $X(x,y) = (2,3)$ and $X'(x,y) = (4,7)$ , then the vector translation is:

$T(x,y) = X'(x,y)-X(x,y)$

$T(x,y) = (4,7) - (2,3)$

$T(x,y) = (2, 4)$

Then, we determine the coordinates for Y' and Z':

$Y'(x,y) = Y(x,y) + T(x,y)$

$Y'(x,y) = (1,4) + (2,4)$

$Y'(x,y) = (3, 8)$

$Z'(x,y) = Z(x,y) + T(x,y)$

$Z'(x,y) =(8,9) + (2,4)$

$Z'(x,y) = (10, 13)$

The coordinates are $Y'(x,y) = (3, 8)$ and $Z'(x,y) = (10, 13)$ .

If these two shapes are similar, what is the measure of the missing length x?

Rus_ich [418]

Answer:

$x=22\ yd$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

$\frac{x}{14}=\frac{77}{49}$

solve for x

$x=\frac{77}{49}(14)$

$x=22\ yd$

A citrus farmer wants to know which of three fertilizers (A, B, and C) is most effective for increasing the number of oranges on

Lyrx [107]

Description of a Randomized block design for the experiment :

Randomized block design involved the divison of subjects into units, called block. After which treatment are randomly applied to elements or subjects in each block.

Here, we make divide the 30 mature trees into 3 which means we have 3 blocks of 10 mature trees each. The citrus fertilizers A, B and C are then applied randomly to each of the three units.

B.)

The randomized block design used in these experiments will correct for the possible error which could be introduced die to systematic error since each of the treatments(fertilizers A, B and C) would be used in each of the blocks.
