Drag statements into order to complete an explanation.

Answer:

2 19/30

Step-by-step explanation:

3 5/6 - 1 1/5

We need to get a common denominator for the fractions

The common denominator is 30

5/6 * 5/5 = 25/30

1/5 * 6/6 = 6/30

3 25/30 - 1 6/30 = 2 19/30

Answer:

\(2\frac{19}{30}\)

Step-by-step explanation:

since this is a mixed fraction we can turn it into 2 equations

3-1

And

5/6-1/5

We know 3-1 is equal to 2 so now for the fraction

To subtract them we have to find a common denominator or multiple for the denominator and one is 30

\(\frac{5x5}{6x5}-\frac{1x6}{5x6}\)

\(\frac{25}{30}-\frac{6}{30}\)

Now we just subtract the numators

25-6=19

We put 19 over 30 and then add the 2 next to it So the solutions is

\(2\frac{19}{30}\)

The equivalent value of the expression \(36^{-(\frac{1}{2})\) is, 1/6.

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

Given, An expression \(36^{-(\frac{1}{2})\).

We know, 6×6 = 36 = 6².

Therefore, \(36^{-(\frac{1}{2})} = (6^2)^{-(\frac{1}{2})\).

\((6^2)^{-(\frac{1}{2})} = (6)^{2\times{-(\frac{1}{2})\).

= 6⁻¹.

= 1/6.

Answer:

The relationship between the number of faces, vertices, and edges of a three-dimensional object is described by Euler's formula, which states that for any polyhedron (a solid object bounded by flat faces), the number of faces (F), vertices (V), and edges (E) satisfy the equation F + V - E = 2. This formula is true for any convex polyhedron, such as a cube or a regular tetrahedron.

The formula is based on the fact that every face of a polyhedron is bounded by a closed loop of edges, and each vertex is where three or more edges meet. The total number of edges is the sum of the number of edges around each face, which is equal to twice the number of faces since each edge is shared by two faces, and the number of edges meeting at each vertex, which is equal to the degree of the vertex (the number of edges meeting at the vertex).

Therefore, by knowing the number of faces, vertices, and edges of a three-dimensional object, we can determine if it is a convex polyhedron and use Euler's formula to check if the numbers are consistent with a solid shape.

Step-by-step explanation:

Any graph shows the set of all solutions to the equation being graphed.

The graph of a linear function is a straight line.

Answer:

\(\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0\)

Step-by-step explanation:

In any right triangle, the following is true:

The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)

The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Answer:

  x = 1

Step-by-step explanation:

You want to know the value of x in the trapezoid with adjacent angles (43x+2)° and 135°.

The two marked angles can be considered "consecutive interior angles" where a transversal crosses parallel lines. As such, they are supplementary.

  (43x +2)° +135° = 180°

  43x = 43 . . . . . . . . . . . . . . divide by °, subtract 137

  x = 1 . . . . . . . . . . . . . . . divide by 43

The value of x is 1.

Additional comment

Given that the figure is a trapezoid, we have to assume that the top and bottom horizontal lines are the parallel bases.

For the given function 'g':

domain = (-4, -2) ∪ (1, 3]

range = (-5, 4]

If the function is defined as f(x) = y, then the values of x for which the value of function exists, the set of that values is said to be the domain of the function f.

If the function is defined as f(x) = y, then the set of all possible values of the function that is the set of all possible values of y is said to be the range of the function f.

Here given the graph of 'g'.

From the graph we can see that for -4 < x < -2 and 1 < x \(\le\) 3 the function has graph.

So the domain = (-4, -2) ∪ (1, 3]

And it is clear that the value of y lies between -5 < y \(\le\) 4.

So the range = (-5, 4].

Answer:

Using DeMoivre’s theorem, the answer in regular form would be (5 + 5√3i)⁷ = -5000000 + 8660254.03i

The De Moivre's Theorem is used to simplify the computation of powers and roots of complex numbers and is used in together with polar form.

Convert the complex number to polar form. The polar form of a complex number is z = r(cos θ + isin θ),

r = |z|  magnitude of z

it becomes

r = √((5)² + (5√3)²) = 10

θ = arg(z) is the argument of z.

θ = atan2(b, a) = atan2(5√3, 5) = π/3

(5 + 5√3i) = 10 × (cos π/3 + i sin π/3)

De Moivre's theorem to raise the complex number to the 7th power

(5 + 5√3i)⁷

= 10⁷× (cos 7π/3 + i sin 7π/3)

= 10⁷ × (cos 2π/3 + i sin 2π/3)

Convert this back to rectangular form:

Real part = r cos θ = 10⁷× cos (2π/3) = -5000000

Imaginary part = r sin θ = 10⁷ × sin (2π/3) = 5000000√3 = 8660254.03i

∴  (5 + 5√3i)⁷ = -5000000 + 8660254.03i

Answer:10^7 (1/2 - √3/2 i)

Step-by-step explanation:

To use DeMoivre's theorem, we first need to write the number in polar form. Let's find the magnitude and argument of the number:

Magnitude:

|5 + 5√(3i)| = √(5^2 + (5√3)^2) = √(25 + 75) = √100 = 10

Argument:

arg(5 + 5√(3i)) = tan^(-1)(√3) = π/3

So the number can be written in polar form as:

5 + 5√(3i) = 10(cos(π/3) + i sin(π/3))

Now we can use DeMoivre's theorem:

(5 + 5√(3i))^7 = 10^7 (cos(7π/3) + i sin(7π/3))

To simplify, we need to find the cosine and sine of 7π/3:

cos(7π/3) = cos(π/3) = 1/2

sin(7π/3) = -sin(π/3) = -√3/2

Explanation:

So the final answer in rectangular form is:

10^7 (1/2 - √3/2 i)

The probability of the announcement being made is 20.5%. Between 11:30 a.m. and 11:40 a.m., the probability of the announcement being made is 12.8%.

Probability is the mathematical study of chance and uncertainty. It is used to quantify the likelihood of an event happening. Probability is based on mathematical calculations and models, so it is an objective measure of the likelihood of something occurring. Probability can be used to make predictions about future events, to measure risk, and to make decisions in uncertain situations. Probability can be used to better understand the world around us and to make better decisions in all aspects of life.

The time of the announcement is an example of a continuous random variable because it is impossible to pinpoint an exact moment when the announcement will be made. The sample space for this variable is the range of times between 11:30 a.m. and noon. The density graph for these data will be bell-shaped, with the highest probability of the announcement being made in the middle of the meeting, as this will be the most likely time for the announcement to take place.

Between 11:40 a.m. and 11:50 a.m., the probability of the announcement being made is 12.8%. In the first 5 minutes of the meeting, the probability of the announcement being made is 20.5%. Between 11:30 a.m. and 11:40 a.m., the probability of the announcement being made is 12.8%.

Number of months  = m

Unknown:

Total cost of gym membership after m months = ?

To solve this problem, we need to follow this world problem step by step;

           Charge for m-months  = $11 x m  = $11m

         Total charge = Sign up fee + charge for m-months
