Name the line of reflection used to map each preimage to its image

rewona [7]

Answer:

From the picture attached,

9). When pre-image KLMN is a reflected across x = -2, we get image K'L'M'N'.

Therefore, line of reflection will be x = -2

10). In this picture line of reflection which passes through origin (0, 0) and slope = 1 will be,

y = x.

11). Since, all the points of image and preimage points are equidistant from x-axis, line of reflection will be x-axis or y = 0.

12). Line passing through midpoint of the line joining BB' will be the line of reflection.

Coordinates of B → (5, 3)

Coordinates of B' → (5, 7)

Coordinates of BB' → → (5, 5)

Therefore, line of reflection will be y = 5.

13). Coordinates of G → (2, 5)

Coordinates of G' → (-2, 5)

Midpoint joining the segment GG' → → (0, 5)

Therefore, line of reflection → x = 0

14). Line of reflection passing through (0, 0) and slope = -1

y = -x

Area of the large semicircle

$= \pi{r}^{2} \div 2$

$= \frac{22}{7} \times 12 {}^{2} \times \frac{1}{2}$

$= \frac{11}{7} \times12 \times 12$

$= \frac{11}{7} \times 144$

$= 226.28$

Area of the small semicircle

$= \pi {r}^{2} \div 2$

$= \frac{22}{7} \times 6 {}^{2} \times \frac{1}{2}$

$= \frac{11}{7} \times 6 \times 6$

$= \frac{11}{7} \times 36$

$= 56.57$

Area of the figure

$= 226.28 - 56.57$

$= 169.71 {cm}^{2}$

Between July 28 and 30 of last year over 41.2 cm (about 16 inches) of rain fell in a city. The normal total monthly rainfall i

ZanzabumX [31]

The amount more of rain that fell in those three days than normally falls in July and August combined was 31.19 cm.

<h3>How much more rain fell in those three days?</h3>

The amount of rain in those three days was 41.2 cm.

The combined normal rain July and August is:

= 6.36 + 3.65

= 10.01 cm

The difference is therefore:

= 41.2 - 10.01

= 31.19 cm
