Which sequences of transformations will map circle M onto circle N?

sergiy2304 [10]

Answer:

1: Reflect M across the x-axis

2: Dilate about the center by 3/2

Step-by-step explanation:

Given

See attachment for M and N

Required

Which maps M to N

The coordinates of the radius of the circles are:

$M = (5,5)$

$N = (5,-5)$

And the radius of circles are:

$r_M=2$

$r_N=3$

The first transformation from M to M' is:

- Reflect across the x-axis

The rule is:

$(x,y) \to (x,-y)$

$M(5,5) \to M'(5,-5)$

At this point, M' and N now have the same center but different radius.

The second transformation from M' to N is:

- Dilate about the center by dividing the radius of N by the radius of M

i.e.

$k =\frac{r_N}{r_M}$

$k =\frac{3}{2}$

At this point, M has been completely mapped to N.

Answer:

$\huge\colorbox{violet}{ᴀɴsᴡᴇʀ}$

Hey There!

The answer = 7 = ( Seventh Track of TS8= Seven )

Step-by-step explanation:

$7x = 49 \\ x = 49 \div 7 \\ x = 7$

$7 \times 1 = 7 \\ 7 \times 2 = 14\\ 7 \times 3 = 21 \\ 7 \times 4 = 28 \\ 7 \times 5 = 35 \\ 7 \times 6 = 42 \\ \bold {7 \times 7 = 49} \\ 7 \times 8 = 56 \\ 7 \times 9 = 63 \\ 7 \times 10 = 7$

Complete the following statement (Picture above)

SOVA2 [1]

For this problem, you would replace x with 7 then solve.

3/ (7+2) - sqrt(7-3) =

3/9 - sqrt(4) =

1/3 - 2 = -1 2/3 = -1.67

f(7) = 1
