Answers

Answer:

[tex]f(x)=-x[/tex]

Step-by-step explanation:

[tex]f(x-2)=2-x[/tex]

To change [tex]f(x - 2)[/tex] into [tex]f(x)[/tex], substitute [tex]x=x+2[/tex]:

[tex]\implies f((x+2)-2)=f(x+2-2)=f(x)[/tex]

Therefore, substitute [tex]x=x+2[/tex] into both sides of [tex]f(x-2)=2-x[/tex]:

[tex]\implies f((x+2)-2)=2-(x+2)[/tex]

[tex]\implies f(x)=-x[/tex]

Let's spot out.

f(x-2)=2-x

Put x+2 in place of x

f(x+2-2)=2-(x+2)f(x)=2-x-2f(x)=-x

Step-by-step explanation:

Δ MAL and Δ DLA are right triangles. If Δ MAL ≅ ΔDLA, then side DL is congruent to side MA, and ∠ MAL is congruent to ∠ DLA. Given ∠ M is 30 °, side DL is (2x + 10) cm, side MA is (3x – 2) cm, and side AL is (x + 5) cm, answer the following questions below:

What is the measurement of DL?

What is the measurement of AL?

What is the measurement of ∠ DLA?

What is the measurement of ∠ AEL?

Answers

Answer:

DL = 34 cm

AL = 17 cm

∠DLA = 60°

∠ADL = 30°

Step-by-step explanation:

Given:

DL = (2x + 10) cmMA = (3x - 2) cm

DL ≅ MA

⇒ 2x + 10 = 3x - 2

⇒ 2x + 12 = 3x

⇒ 12 = x

Substituting found value of x into expressions for DL and AL:

DL = 2x + 10

= 2(12) + 10

= 34 cm

AL = x + 5

= 12 + 5

= 17 cm

The only way for ΔMAL to be a right triangle, with MA = 34 cm, AL = 17 cm and ∠M = 30° is if

MA is the hypotenuseAL is the shortest side

Given:

∠M = ∠D = 30°∠MAL ≅ ∠DLA

Sum of interior angles of a triangle is 180°

⇒ ∠DLA + 30° + 90° = 180°

⇒ ∠DLA + 120° = 180°

⇒ ∠DLA = 60°

As ∠M = ∠D = 30°, then ∠ADL = 30°

Answer:

DL = 34 cmAL = 17 cm∠DLA = 60°∠ADL = 30°

Step-by-step explanation:

Given:

DL = (2x + 10) cmMA = (3x - 2) cmDL ≅ MA

Equating DL and MA :

⇒ 2x + 10 = 3x - 2

⇒ 2x + 12 = 3x

⇒ x = 12

Finding DL and AL :

DL = 2(12) + 10 = 24 + 10 = 34 cmAL = 12 + 5 = 17 cm

Finding ∠DLA :

∠M = ∠D = 30° (corresponding parts of congruent triangles)∠DLA + ∠D + 90° = 180°∠DLA + 30° = 90°∠DLA = 60°

Finding ∠ADL :

∠ADL = ∠D∠ADL = 30°

cscθ is the same as 1/sinθ

Explanation:

csc stands for cosec which is equivalent to 1/sinθ

The expression is thus equal to 1/[sin⁡(4π/3)]

Since we know by consulting the unit circle that sin⁡(4π/3) = - [(√3)/2]

we get the expression 1/[sin⁡(4π/3)] = 1/(-√3/2)

which can be simplified to 1/(-√3/2) = 2/(-√3) = (-2√3)/3

What is the general equation of a cosine function with an amplitude of 3, a period of 4 pi, and a horizontal shift of negative pi? y = 4 pi cosine (3 (x minus pi)) y = 3 cosine (4 pi (x pi)) y = 3 cosine (0.5 (x pi)) y = 4 pi cosine (0.2 (x pi))

Answers

The general equation of a cosine function with an amplitude of 3, a period of 4 π, and a horizontal shift of negative π is [tex]f(x) =3cos(0.5x+\pi )[/tex].

What is a function?

A function is a rule that relates two variables.

The parent function is:

[tex]f(x)=cosx[/tex]

We know the period of the parent function is 2π and the amplitude is 1.

For an amplitude of 3, we need to multiply the parent function by 3.

So, the function with amplitude 3 will be given by:

[tex]f(x) =3cosx[/tex]

For a period of 4π, we need to make the argument of the parent function half.

So, [tex]f(x) = 3cos(0.5x)[/tex]

A horizontal shift of negative π means, f(x) will become f(x+π)

So, [tex]f(x) =3cos(0.5x+\pi )[/tex].

Therefore, the general equation of a cosine function with an amplitude of 3, a period of 4 π, and a horizontal shift of negative π is [tex]f(x) =3cos(0.5x+\pi )[/tex].

Step-by-step explanation:

Formulae

Area of a triangle = 1/2 x base x heightArea of a rectangle = width x length

The shape is made up of 2 congruent triangles and 3 different rectangles.

Area of triangle = 1/2 x 3 x 4 = 6 ft²

Area of rectangle 1 = 2 x 4 = 8 ft²

Area of rectangle 2 = 2 x 3 = 6 ft²

To calculate the area of the 3rd triangle, we need to use Pythagoras' Theorem to determine the length of the hypotenuse of the right triangle.

a² + b² = c²

⇒ 3² + 4² = c²

⇒ 25 = c²

⇒ c = √(25)

⇒ c = 5 ft

Therefore, area of rectangle 3 = 2 x 5 = 10 ft²

Total Surface Area

Total SA = 2 triangles + rectangle 1 + rectangle 2 + rectangle 3

= (2 x 6) + 8 + 6 + 10

= 36 ft²

a radio mast is supported by 4 cables, each of which is attached to the top of the mast. The depression from the top of the mast to the base of one of the supporting cables is 55 degrees. the height of the mass is 213 metres. work out the length of the cable

Answers

The cable and the mass forms a right triangle

The length of the cable is 260 meters

How to determine the length of the cables?

The given parametes are:

Angle = 55 degrees

Height of the mass (h) = 213 meters

The length of the cable (l) is calculated using the following cosine ratio

cos(90 - θ) = h/l

Substitute known values

cos(90 - 55) = 213/l

cos(35) = 213/l

Make l the subject

l = 213/cos(35)

Evaluate the quotient

l = 260.024987406

Approximate

l = 260

Hence, the length of the cable is 260 meters
