Step-by-step explanation:

$\frac{ {x}^{2} + 1 }{1} \times \frac{1}{x} = \frac{ {x}^{2} + 1 }{x}$

X cannot equal zero so all real numbers expect zero.

Please help me. Noura is redecorating her house. She needs to work out the area of the wall around her triangular window in orde

Vinvika [58]

Answer:

a. 277.3 m²

b. $307.86

Step-by-step explanation:

a. Area of the wall to be painted = area of rectangle - area of triangle

= L × W + ½×a×b×sin θ

L = 17 m

W = 14 m

a = 8.7 m

b = 9.5 m

θ = 72°

Plug in the values into the equation

Area of the wall = (17×14) + (½*8.7×9.5×sin 72)

Area of the wall = 238 + 39.3024105

Area of the wall to paint ≈ 277.3 m²

b. 20 liters of paint of 1 container cost $21.99

If 1 liter of paint covers 1m², therefore,

277.3 m² will need = 277.3 × 1 = 277.3 liters of paint.

20 liters = 1 container of paint

277.3 liters = 277.3/20 = 13.865 ≈ 14 containers

1 container = $21.99

14 containers = 21.99 × 14 = $307.86

Polygons QRST and Q′R′S′T′ are shown on the following coordinate grid: A coordinate plane with two polygons is shown. Polygon QR

creativ13 [48]

As you can see from the picture you have:
to rotate point S about the origin by $90^0$ clockwise to form point S'';
to rotate point R about the origin by $90^0$ clockwise to form point R'';
to rotate point Q about the origin by $90^0$ clockwise to form point Q'';
to rotate point T about the origin by $90^0$ clockwise to form point T''.
Then you have to translate polygon Q''R''S''T'' 1 unit down.
Note that rotation $90^0$ clockwise is the same as rotation $270^0$ counterclockwise, so the correct answer is rotating $270^0$ counterclockwise about the origin and translating 1 unit down.
