How many significant figures does the number 1.006 x 10⁷ have?A) 3B) 4C) 5D) 6E) 8

Answer:

Step-by-step explanation:

-2(x-3)=-6(x+4)     [Original Equation]

-2x+6=-6x-24      [remove the parentheses]

?   -2x+6x+6 =-24   [add 6x to both sides]

   4x + 6 = -24      [combine like terms]

    -2x+6x+6=-6x-24+6x  [Add 6x to both sides]

    4x+6x+6=-6x-24+6x

    -2x+6x+6=-24    [Add 6x and subtract 6 from both sides]

    4x + 6 = -24     [This step is justified by the additive property of equality.]

Answer:

  28 +8√5 ≈ 45.89 cm

Step-by-step explanation:

You want the perimeter of an isosceles trapezoid with bases 10 and 18 cm and height 8 cm.

The length of each side of the trapezoid is the hypotenuse of a right triangle with legs 4 and 8:

  c² = a² +b²

  c² = 4² +8² = 16 +64 = 80

  c = √80 = 4√5 . . . . . . length of one side of the trapezoid

The perimeter is the sum of the lengths of the sides and the bases:

  10 + 18 + 2(4√5) = 28 +8√5 . . . . . cm

The perimeter is 28 +8√5 ≈ 45.89 cm.

In order to prove that ∠MPQ is congruent to ∠MLN, she requires that PQ and LN should be parallel.

What are parallel lines?

When two lines in a plane do not cross at any point, they are said to be parallel. Lines that never cross paths with one another and do not have a common junction point are said to be parallel. They are equally spaced apart and have the same incline.

We know that corresponding angles of parallel lines are equal.

As shown in the figure, ∠MPQ and ∠MLN are corresponding angles.

So, if she is provided that PQ and LN are parallel, then, she can prove that ∠MPQ is congruent to ∠MLN and thus, the triangles are similar.

Hence, she requires that PQ and LN should be parallel.

The distance between pylon B and pylon C is 1017.60 m, using the Pythagorean theorem.

The Pythagorean Theorem, also known as Pythagoras' Theorem, states that the area of the large square is equal to the sum of the areas of the two smaller squares.

In terms of algebra, the triangle's a and b are its legs, and its hypotenuse is equal to its product, a2 + b2 = c2.

Since it provides the foundation for the definition of distance between two points in Euclidean geometry, the theorem is crucial. Anyone who took geometry in high school, in my opinion, cannot possibly fail to remember it long after other math concepts have been completely forgotten because it is so fundamental and well-known.

Using Pythagorean theorem

The hypotenuse is the Distance from pylon B to pylon C

c = [tex]\sqrt{a^2 + b^2}[/tex]

Distance from pylon B to pylon C =  [tex]\sqrt{845^2 + 567^2}[/tex]

                                                        = 1017.60 m

The factors of 9x² – 3x – 20 is (3x+4)(3x−5).

A number or other mathematical object is factorized or factored when it is written as the product of numerous factors, usually smaller or simpler things of the same kind.

Factorization in mathematics is the method of dividing a large number into tiny ones that, when multiplied together, give you the original number. Factorization is the split of a number into its factors or divisors.

We can also format it as

9x²−3x−20=9x²−15x+12x−20

by avoiding the everyday language

9x²−3x−20=3x(3x−5)+4(3x−5)

hence, we do

9x²−3x−20=(3x+4)(3x−5)

Answer: (5y+6)/2

Step-by-step explanation:

The inverse of f(x) = log₁₀(x) is 10ˣ.

A logarithm is an exponent to which a base must be raised to generate a given number. Expressed mathematically, x is the logarithm of n to the base a if ax = n, in which case one writes x = logₐn.

A logarithm is defined using an exponent.

aˣ = b ⇔ logₐb = x

Here, "log" stands for logarithm. The arrow's right part is read as "Logarithm of b to the base a is equal to x".

We have the function,

f(x) = log₁₀(x)

Let y = f(x)

⇒y = log₁₀(x)

⇒[tex]10^{y}[/tex] = x

∴[tex]f^{-1}[/tex](x) = 10ˣ

Yes, the number, 4225, is a perfect square because it can be expressed as square of 65 which is a whole number, i.e., 4225 = 65².

In mathematics, a square number or perfect square is an integer that is the product of some integer with itself. For example, 25 is a square number, it is equals to 5² and can be written as 5×5. A perfect square always represented as second power of a number. Perfect Square Formula : Let us consider if N is a perfect square of a whole number x, then it can be written as N = product of x and x = x². So, the perfect square formula is, N = x². We have a number 4225. Now, we resolve 4225 into prime factors, we get, 4225 = 5×5×13×13 = 5×13×5×13

= 65×65 = (65)²

Hence, the square of 65 results 4225. Therefore, 4225 is a perfect square.

Answer: Area = 28.3cm²

               Circumference =  18.9cm

Step-by-step explanation:

Area = πr²

        = π × 3²

        = 28.27

        = 28.3cm² (estimate to 3s.f always)

Circumference = 2πr

                          = 2 x π x 3

                          = 18.85

                          = 18.9cm (estimate to 3s.f always)

The area and the circumferences of the circle are 28.27 square meters and 18.85 meters.

Given is a circle with radius 3m we need to determine the area and the circumferences of the circle,

To determine the area and circumference of a circle with a radius of 3m, we can use the following formulas:

Area of a circle: A = πr²

Circumference of a circle: C = 2πr

Here, "r" represents the radius of the circle, and "π" (pi) is a mathematical constant approximately equal to 3.14159.

Let's calculate the values:

Area:

A = πr²

A = 3.14159 x (3m)²

A = 3.14159 x 9m²

A ≈ 28.27 square meters

Therefore, the area of the circle is approximately 28.27 square meters.

Circumference:

C = 2πr

C = 2 x 3.14159 x 3m

C ≈ 18.85 meters

Therefore, the circumference of the circle is approximately 18.85 meters.

Hence the area and the circumferences of the circle are 28.27 square meters and 18.85 meters.

No, Since earthquake waves lose energy as they move through the earth, shaking is less powerful away from the fault. Compared to high-frequency waves, low-frequency waves lose strength across distance more slowly.

The magnitude scale, which measures an earthquake's size, is unaffected by distance from the event. The extent of damage depends on how violently the ground shakes when an earthquake occurs.

The depth of the earthquake, the distance from the fault, the underlying soil, and the characteristics of the buildings, particularly their height, intensity, are the subsequent primary elements impacting earthquake shaking strength. The brightness of a celestial object, like a star or galaxy, as judged by an observer at a particular distance from the object is known as its apparent magnitude.

The equation for g(x) would be g(x) = 9cos(x-1) ^3 + 4.

This is because the function M(x) = 9cos(x)^3 represents a cosine function cubed, which results in a three-dimensional graph that oscillates and has multiple local maxima and minima. By translating the function one unit left, represented by the subtraction of 1 from the x value inside the cosine function, the entire graph is shifted one unit to the left.

The translation of 4 units up is represented by the addition of 4 to the overall function. This means that the entire graph of g(x) is now 4 units higher than the original function M(x).
