After a rotation, A(-3,4) maps to A/4, 3), B(4.-5) maps to BY-5,-4), and C(1,6) maps to C(6.-1). Which rule
sineoko [7]

Answer:

3rd option

Step-by-step explanation:

Under a rotation about the origin of 270°

a point (x, y ) → (y, - x ) , then

A (- 3, 4 ) → (4, - 3 )

B (4, - 5 ) → (- 5, - 4 )

C (1, 6 ) → (6, - 1 )

The point A = (7,4) is dilated from the origin by a scale factor r = 3. What are the coordinates of A' ?
fomenos

Given:

The coordinates of point A are (7,4).

It is dilated from the origin by a scale factor r = 3.

To find:

The coordinates of A'.

Solution:

If a figure is dilated from the origin by a scale factor k, then

(x,y)\to (kx,ky)

Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:

(x,y)\to (3x,3y)

Using this rule, we get

A(7,4)\to A'(3(7),3(4))

A(7,4)\to A'(21,12)

Therefore, the coordinates of point A' are (21,12).

Answer:

x^4 + 4x^3 + 6x^2 + 7x + 2

Step-by-step explanation:

We are asked to multiply the given polynomials.

(x^ 2 + 3x + 1) \times (x^2 + x + 2)

Multiply each term of the first polynomial to each term of the second polynomial.

x^ 2  \times (x^2 + x + 2) = x^4 + x^3 + 2x^2

3x  \times (x^2 + x + 2) = 3x^3 + 3x^2 + 6x

1 \times (x^2 + x + 2) =  x^2 + x + 2

Add the results

(x^4 + x^3 + 2x^2) + (3x^3 + 3x^2 + 6x) + ( x^2 + x + 2)

Combine the like terms

x^4 + 4x^3 + 6x^2 + 7x + 2

The answer is written in descending powers of x.
