Kite ABCD is translated (x − 2, y + 3) and then rotated 90° about the origin in the counterclockwise direction. Complete the tab

il63 [147K]

If the resulting coordinate is rotated 90° about the origin in the counterclockwise direction, the final coordinate will be at A'' = (-4, -7), B'' =(-5, -4), C'' = (-4, -3) and D'' =(-3, -4)

Given the coordinate of the vertices ABCD given as

A = (-5, 1)

B = (-2, 2)

C = (-1, 1)

D (-2, 0)

If the coordinates are translated by (x − 2, y + 3), the resulting coordinates will be at:

A' = (-5-2, 1+3) = (-7, 4)

B' = (-2-2, 2+3) = (-4, 5)

C' = (-1-2, 1+3) = (-3, 4)

D' (-2-2, 0+3) = (-4, 3)

If the resulting coordinate is rotated 90° about the origin in the counterclockwise direction, the final coordinate will be at (-y,x)

A'' = (-4, -7)

B'' =(-5, -4)

C'' = (-4, -3)

D'' =(-3, -4)

Two weather stations are aware of a thunderstorm located at point C. The weather stations A and B are 27 miles apart. How far is

cluponka [151]

Station A is at a distance of 28.83 miles from the storm

Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:

$\frac{a}{sin(A)}= \frac{b}{sin(B)}=\frac{c}{sin(C)}$

From the diagram:

A = 34° + 90° = 124°

Also:

B = 90° - 61° = 29°

Hence:

C + A + B = 180°
C + 29 + 124 = 180
C = 27°

b = distance station A from the storm, c = AB = 27 miles

Using sine rule:

$\frac{c}{sin(C)} =\frac{b}{sin(B)} \\\\\frac{27}{sin(27)}=\frac{b}{sin(29)} \\\\b=28.83\ miles \\$

Station A is at a distance of 28.83 miles from the storm

Lucy is tiling her bathroom. She buys white and blue tiles in the ratio 13:2.Blue tiles cost £2.80 while white tiles cost £2.35.

krok68 [10]

Answer:

* Lucy spent £289.2 on tiles *

Step-by-step explanation:

We know that the tiles are present in a 13 to 2 ratio ( 13 : 2 ) so if there are 16 blue tiles that she buys, the number of red tiles bought should be represented the following -

$\frac{13}{2}$ = $\frac{x}{16}$ ... now this is only assuming that the 13 : 2 ratio is meant by white : blue tiles. Let's solve through cross - multiplication,

13 $*$ 16 = 2 $x$ ,

208 = 2 $x$ ,

$x$ = 104 white tiles

So if there are 104 white tiles, and 16 blue tiles, we can determine the total amount Lucy spent on tiles by associating the cost to the type of tile,

£2.80 $*$ 16 = £44.8,

£2.35 $*$ 104 = £244.4,

Total Amount Lucy Spent on Tiles = £44.8 + £244.4 = £289.2
