Task 3: A sequence of transformations was applied to triangle ABC to result in A"B"C". First, ABC was rotated 90 counterclockwise around the
origin to get A'B'C'. Then a translation resulted in A"B"C".
1. What are the coordinates of A'B'C' after the rotation?
(Hint: you need to do the rotation)
A’ ( , )
B'( , )
C'( , )

2. What is the algebraic description of the translation in
this sequence? (Hint: A'B'C' is the preimage: A”B”C” is the image.)
(x, y) → (X —————, y ————-)
(Include both the sign and the number)

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
