Answers

Answer:

a. False : because 10^-5= 1/10^5 where as -10^5=-1 × 10^5

therefore 1/10^5 not equal to -1×10^5

b. False : because (10^2)^-3 = 100^-3=1/100^3 where as (10^2)^3 = 100^3=1000000 there fore 1/100^3 not equal to 1000000

c. True : because 10^3/10^14=10^(3-14)=10^-11 therefore both left side and right side of the equation are equal

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°

Miranda is calculating her expected expenses for her week long trip to turkey. her flight costs 928 tl (turkish lira), her lodging costs 755 tl, and she has allowed 814 tl for food and spending money. what is miranda’s total? a. 4,762 tl b. 2,497 tl c. 869 tl d. 641 tl

Answers

The addition is the process of adding two numbers and the result is the combined value of the two numbers. Miranda's total will be equal to 2497 Turkish lira.

What is Addition?

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

The total cost will involve the cost of Miranda's flight, her lodging costs, and the cost of food and other such spending. Therefore, her total is the sum of all of this expenses,

Miranda's Total

= cost of flight + lodging costs + cost of food and other spending

= 928 ti + 755 ti + 814 ti

= 2497 ti

Hence, Miranda's total will be equal to 2497 Turkish lira.

What is x?​

Answers

Answer: Between 1 and 3.

Step-by-step explanation:

You have to Think about y too, y can be anything, but let's say y is 1. Then x should be 3

x = 4, y = 6

In this case, you can solve the equation by substitution.

3x + 4y = 36

We are given that y = -1/2x + 8

Plug in that value assigned to y.

3x + 4(-1/2x + 8) = 36

3x -2x + 32 = 36

x + 32 = 36

x = 4

Now, we can return back to y

y = -1/2x + 8

y = -1/2(4) + 8

y = -2 + 8

y = 6

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 isand 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].

cscθ is the same as 1/sinθ

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

During which time period was the ANNUAL rate of increase of the speed the GREATEST

Answers

Answer:

1-2

Step-by-step explanation: because it went up in speed by 8 and the rest went up not even to 7

Based on the table, we can deduce that the annual rate of increase of the speed was the greatest: A. from year 1 to year 2.

What is speed?

Speed can be defined as the distance covered by an object per unit of time. Thus, speed can be measured as meter per seconds.

Mathematically, speed is given by this formula;

[tex]Speed = \frac{distance}{time}[/tex]

Based on the table, we can deduce that the annual rate of increase of the speed was the greatest from year 1 to year 2.

Rate = 46 - 38 = 8.
