Answer:

1. Reflection

2. rotation and reflection

3. b', b''

4. 26.3

Step-by-step explanation:

1. It is like looking in a mirror. Its is being reflected across the y axis

2. It is rotated 90 degrees to the right. Then reflected over the x axis.

3. they are the same

4. It is the same as A" B" C" D" so the lengths are the same and you just add them.

Responder:

$ 555,911.5

Explicación paso a paso:

Dado

Principal = $ 545,680

Interés = 2,25%

Tiempo = 10 meses = 10/12 años

Debemos buscar la cantidad después de 10 meses.

Monto = Principal + Intereses

Interés = PRT / 100

Interés = 545,680 * 2,25 * 10/1200

Intereses = 12,277,800 / 1200

Interés = 10.231,5

Cantidad = 545,680 + 10,231.5

Cantidad = 555,911.5

por lo tanto, la cantidad después de 10 meses es $ 555,911.5

Answer:

No it's not

Step-by-step explanation:

In a right triangle the longest side is always the Hypotnuse. With legs a and b and Hypotnuse c, all right triangle follow the Pythagoream Theorem (a^2+b^2=c^2)

If this is a right triangle then it should also follow this rule.

8^2=4^2+6^2

64=16+36

64≠52

So this isn't a right triangle

We can find the solution to the answer by using the Pythagorean Theorem.

a² + b² = c²

4² + 6² = 8²

16 + 36 = 52

8² = 64

52 ≠ 64.

Since 4² + 6² does not equal 8², a triangle with the sides 4, 6, and 8, are not a right triangle.

Answer:

The answer is "[tex]\bold{\frac{\pi}{6}}[/tex]"

Step-by-step explanation:

[tex]\to 3 \tan(x) = 2 \sin(2x) \\\\[/tex]

[tex]\to 3 \frac{\sin x}{\cos x} = 2 2\sin x \cos x \\\\\to 3 \frac{\sin x}{\cos x} = 4\sin x \cos x \\\\\to \frac{\sin x}{\cos x \sin x \cos x } = \frac{4}{3} \\\\\to \frac{1}{\cos^2 x } = \frac{4}{3} \\\\\to \sec^2 x = \frac{4}{3} \\\\\to \sec x = \frac{2}{\sqrt{3}} \\\\\to \sec x= \sec \frac{\pi}{6} \\\\ \to x= \frac{\pi}{6}[/tex]

2.5/5=5/Summer's shadow

Summer's shadow=25/2.5

Summer's shadow=10 feet

Answer:

C. 15

Step-by-step explanation:

[tex]a^2 + b^2 = c^2[/tex] a= 9 b = 12. which would = 225

[tex]\sqrt{225}[/tex] = 15

Answer:

c. 15

Step-by-step explanation:

A right triangle can use the pythagorean theorem. Using this theorem you should get

[tex]12^2 + 9^2 = c^2\\c=\sqrt{144+81} \\c=15[/tex]

Answer:

4x - 2 = 6

add 2 on both sides

4x = 8

divide by 4

x = 2

Answer:

x = 17.6

Step-by-step explanation:

use sine

⇒ sine = [tex]\frac{opposite}{hypotenuse}[/tex]

⇒ sine 62 = [tex]\frac{20}{x}[/tex]

sine of 62 is 0.88

⇒ 0.88 =  [tex]\frac{20}{x}[/tex]

multiply 20 on both sides

⇒ 0.88 x 20 =  [tex]\frac{20}{x}[/tex] x 20

⇒ 17.6 = x

Answer:

(x+36) (x-4)

Step-by-step explanation:

x²+32x-144=0

x²+36x-4x-144=0

x(x+36)-4(x+36)=0

(x+36) (x-4)

Answer:

82 is 42 degrees warmer than 40

Step-by-step explanation:

if you subtract 40 from 82, you get 42 meaning that the answer will be 42 degrees more than 40

Answer:

24,000 cm³

Step-by-step explanation:

Answer:

V = 48000 cm³

Step-by-step explanation:

The volume (V) of the prism is calculated as

V = area of end face × length

The end face is a trapezium with area (A) calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 20 , b₁ = 10 and b₂ = 30 , then

A = [tex]\frac{1}{2}[/tex] × 20 × (10 + 30) = 10 × 40 = 400 cm²

Thus

V = 400 × 120 = 48000 cm³
